P r efa ce
This manual documents functionality for the MPE/iX releases, for
HP e3000 systems. It describes the concepts and terminology needed to
design an NS 3000/iX network and to plan the configuration process for
that network. It also provides step-by-step instructions to assist you in
configuring the network links for HP e3000 systems.
Audience
This manual is intended for network managers and planners who are
responsible for setting up and configuring a communications network.
To make the best use of this guide, you should be familiar with basic
MPE commands as well as with the NS 3000/iX product.
You should also be familiar with NMMGR, the tool used to configure
network connections. If not, refer to Using the Node Management
Services (NMS) Utilities for information.
Special Note
MPE/iX, Multiprogramming Executive with Integrated POSIX, is the
latest in a series of forward-compatible operating systems for the
HP e3000 line of computers.
In HP documentation and in talking with HP e3000 users, you will
encounter references to MPE XL, the direct predecessor of MPE/iX.
MPE/iX is a superset of MPE XL. All programs written for MPE XL will
run without change under MPE/iX. You can continue to use MPE XL
system documentation, although it may not refer to features added to
the operating system to support POSIX (for example, hierarchical
directories).
Finally, you may encounter references to MPE V, which is the operating
system for HP e3000s, not based on the PA_RISC architecture. MPE V
software can be run on the PA_RISC HP e3000s in what is known as
compatibility mode.

This manual provides step-by-step instructions you can use to configure
an HP e3000 node for network communications. You can use the
information to configure an IEEE 802.3/Ethernet, Token Ring, FDDI,
100VG-AnyLAN, 100Base-T, Point-to-Point (router), or X.25 node.
Before you begin configuration, you must ensure your network is
physically set up and ready for network configuration.
This chapter provides information you should know before you begin
configuration. It tells you what preparations you must make and what

Once you have verified that your hardware has been correctly installed,
verify that the appropriate software is installed by performing the
following steps:
1. Ensure that the Datacommunications and Terminal Subsystem
(DTS) has been configured. If DTS has not been configured, refer to
Configuring Systems for Terminals, Printers, and Other Serial
Devices and configure the DTS before proceeding.
2. Check that the data communications software has been installed
properly by running the NMMAINT program (NMMAINT.PUB.SYS),
which is supplied as part of the node management services.
NMMAINT will tell you if any software modules are missing or
invalid. See the Using the Node Management Services (NMS)
Utilities manual for a discussion of the NMMAINT program.
3. Whenever you receive a new version of the node management
services (NMS) software (which includes NMMGR), and you have
earlier versions of NMS, you first have to run a conversion program.
The conversion program, called NMMGRVER (NMMGRVER.PUB.SYS),
ensures that configuration files created with an earlier version of
NMMGR are converted to the latest format.

The instructions in this guide explain how to configure each node on
your network by using a “guided” branch of Hewlett-Packard’s NMMGR
configuration program. The principal steps in this process are as
follows:
1. Plan your network before you begin NMMGR. Use the worksheets
2. Configure the transport and link by using NMMGR to modify the
NMCONFIG.PUB.SYSfile. The instructions for this step are contained
in this manual.
3. If the node being configured is part of an internet or is on a network
with non-HP nodes, add the path of the new node to its network
for information on configuring the network directory, or if using DNS
for nodename resolution.

Netw or k in g Con cep ts
Planning a network or internetwork (collection of networks) is an
important process that must be done with care to ensure that the
network meets the needs of your organization. Many factors must be
taken into consideration when planning the network or internetwork:
for example, volume of usage over particular links, volume of CPU
usage of each node, physical layout needs and limitations (such as
geographical distances), and desirability of connections to
non-NS 3000/iX nodes.
This chapter provides information to help you design your network and
plan for configuration using NMMGR. The following network design
elements are discussed:

Networking Concepts
Network Environment Design Considerations
Netw or k En vir on m en t Design Con sid er a tion s
Network and internetwork design must take many factors into
consideration: the desired physical location of the computers
comprising the network, the volume of projected communications traffic
between nodes, communications traffic patterns, and the possibility of
connections to other types of nodes (such as those in a public data
network) are just some of the criteria to consider.
These factors will affect your choice of NS network type (LAN, Token
Ring, FDDI, 100VG-AnyLAN, 100Base-T, Point-to-Point, X.25) as well
as choice of specific links. They will also affect how you design your
network layout. You may want to create subnetworks within your
network by configuring IP subnet addresses. You may, on the other
hand, need to join several networks together to form an in ter n etw or k
or in ter n et.
Lin e Sp eed
Line Speed is a measure of the rate at which data is transmitted by a
physical link (usually measured in kilobits or megabits per second). The
maximum line speed varies among different NS links. Line speed may
therefore influence your choice of link. Although line speed does not
indicate the exact throughput of a particular link, it can be used on a
comparative basis to indicate relative throughput.
In general, an IEEE 802.3/Ethernet LAN or Token Ring network will be
faster than a Point-to-Point or X.25 network because the bus or ring
topology provides a faster routing mechanism than a series of
Point-to-Point hops. FDDI, 100VG-AnyLAN, and 100Base-T links will
be an order of magnitude faster than LAN or Token Ring. Links using
leased lines will have a higher line speed than links using normal
telephone lines.
Consult your Hewlett-Packard representative for line speeds and the
most up-to-date performance data for various links.
Geogr a p h ica l Loca tion
The geographical location of the computers that will be part of your
network or internet will be an important factor in deciding both the
physical topology and the link types that you should use.
If all of the nodes you want to connect are located relatively close to
each other (in the same building, for example) you might choose to
connect them via a LAN, Token Ring link, 100VG-AnyLAN, or
100Base-T.
Another option for nodes located in the same geographic location is to
use hardwired (direct-connect) Point-to-Point links. You might wish to

Networking Concepts
Network Environment Design Considerations
use a Point-to-Point network if the distance between some nodes on the
network will be greater than the maximum distance allowed between
nodes on a LAN. Bridges, hubs and routers are commonly implemented
to extend LANs.
FDDI networks also offer greater distances than LAN, Token Ring,
100VG-AnyLAN, or 100Base-T networks. FDDI networks can be up to
200 kilometers in length, with nodes up to 2 kilometers apart.
If you need to connect nodes that are geographically distant (for
example, HP e3000s located in different cities) you might choose to
connect them via a dial link. For NS dial links, you can use the
Point-to-Point 3000/iX Network Link.
Finally, if you need to use satellite transmission because of the large
geographical distance between nodes, or if you need to have access to
other nodes on a public or private X.25 network, you might wish to use
the DTC/X.25 iX Network Link.
Sp ecia l Ca ses
The following sections describe certain design requirements for special
situations, such as shared dial links, personal computers, and using
non-HP e3000 minicomputers on an NS network.
Sh a r ed Dia l Lin k s
Shared dial links have two limitations that must be considered when
designing a network. First, a shared dial link cannot be used as an
intermediate link in a Point-to-Point network. Any other kind of dial
link can be used for intermediate links, but shared dial links can be
used only to connect leaf nodes (that is, nodes that receive messages
targeted only for themselves, also referred to as end nodes). Second,
cannot dial out on SMUX, shared dial links cannot be used as gateway
halves.
Non -HP e3000 Nod es (In clu d in g P Cs)
LAN, Token Ring, FDDI, 100VG-AnyLAN, 100Base-T, and X.25
networks can access non-HP e3000 nodes. Point-to-Point networks
must be composed of only HP e3000s.
Ap p lica ble SYSGEN Pa r a m eter s
VT terminals are not physical devices, instead they are virtual devices
created dynamically at remote logon, header entries are created for the
maximum number of VT terminals at system boot time. The exact
number of head entries created for VT terminals will depend on the
value of MAXDYNIO (which is configurable in SYSGEN).
The exact number of remote sessions which can be supported on a given
system will depend on the exact mix of jobs and sessions (remote and
local, active and inactive) on that system.

The maximum number of concurrent processes may limit the number of
remote logons before the maximum number of dynamic I/O devices
does.
Dyn a m ic Ld evs
This is actually a system parameter that can be configured to 999 in
SYSGEN. The default is 332, but the actual number that can be in use
may be limited by the IDD/ODD limits. VT and NS use one dynamic
ldev per remote session and one per LAN link and one per
Point-to-Point link.
NOTE
The result of having DYNAMIC IO DEVS configured too low for NS
VIRTUAL TERMINAL connections is VTERR 8 or VT INFORM 050.
Likewise the dynamic I/O device limit may be reached before the
concurrent process limit.

Network Interface and Link Types
Netw or k In ter fa ce a n d Lin k Typ es
The network interface (NI), the software that provides an interface
between a node and a network, specifies the type and maximum
number of links that can be configured for a node. Because a node’s
network interface determines what links can be configured for the node,
links are said to be configured underneath network interfaces.
There are nine types of network interfaces (in addition to loopback):
•
LAN for IEEE 802.3 and Ethernet networks, 100VG-AnyLAN
networks, and 100Base-T networks.
•
•
•
•
•
•
•
Tok en Rin g for IEEE 802.5 networks.
F DDI for fiber optic networks.
100VG-An yLAN for 100VG-AnyLAN networks.
100Ba se-T for 100Base-T networks.
Poin t-to-Poin t for networks that use Point-to-Point routing.
X.25 for X.25 networks.
NS over SNA is no longer offered as a product and has been
removed from the Corporate Price List. The product is obsolete with
no plans for support.
•
Ga tew a y h a lf for nodes that function as gateway halves.
Nu m ber of Netw or k In ter fa ces
A system can have up to 48 network interfaces (NI) configured. One of
these network interfaces must be loopback. For each network interface,
the maximum number of links you can configure and the kinds of links
possible are determined by the network interface type, as follows:
•
A LAN network interface can have only one link configured under it;
however, a single link can reach a large number of nodes. ThickLAN
cable supports up to 100 nodes per segment; ThinLAN cable can be
used for up to 30 nodes per segment; and each Ethertwist 3000/iX
can be used for up to 50 nodes. Up to tw o LAN NIs ca n be a ctive

•
A Token Ring interface can have only one link configured under it;
however, a single link can reach a large number of nodes. Token Ring
3000/iX Network Link can support up to 250 nodes per ring using
shielded twisted pair (STP) cabling at 4 or 16 Mbps and 50 nodes per
ring using unshielded twisted pair (UTP) cabling at 4 Mbps. On ly

An X.25 network interface can have from one to 11 links configured,
depending on the number of configured X.25 network interfaces on
the node. (A single node can have up to 11 NIs and up to 11 X.25
links.) Each link can be connected to as many as 1,024 remote nodes,
with communication allowed with as many as 256 nodes at the same
time. Up to 11 X.25 NI’s ca n be a ctive a t a tim e (on e NI m u st be

halves can be only NS Point-to-Point 3000/iX Network links. On ly

If more than one (non-loopback) network interface is configured on a
node, the network portions of the IP addresses configured for the
interfaces should differ to correspond to the multiple networks to which
the node belongs.
Refer to “Software Configuration Maximums” at the end of this chapter
for information on configuration path maximums.
P r ior ity of Netw or k In ter fa ces
If it is possible to reach a destination through more than one active NI,
the network determines which NI to select according to the following
priority:

If more than one NI of a given type is active, (for example, two X.25
NIs) the network will select the one that it finds first.

Networking Concepts
Subnetworks
Su bn etw or k s
IP Subnets are used to divide one network into two or more distinct
subnetworks. Subnet numbers identify subnetworks in the same way
that network addresses identify physically distinct networks.
Subnetting divides the node address portion of an IP address into two
portions—one for identifying a specific subnetwork and one for
identifying a node on that subnetwork.
Wh y Use Su bn ets?
The use of subnets is optional. Subnets are typically used in
organizations that have a large number of computers. You may want
two or more physically distinct networks to share the same network
address. This may occur, for example, if your organization has acquired
only one network number, but any of the following is true:
•
A few nodes on a single network create the bulk of the network
traffic and you want to isolate those nodes on a subnetwork to reduce
overall congestion.
•
•
You have a single LAN and have reached the limit of its technology
in terms of node numbers or cable length.
LANs are located too far apart to be joined with bridges.
How Su bn ettin g Wor k s
You may use subnets to divide your current network into subnetworks
without informing remote networks about an internal change in
connectivity. A packet will be routed to the proper subnet when it
arrives at the gateway node. However, if you want a remote node to
know about only some of the subnets on your network, this must be
configured.
The network portion of an IP address must be the same for each
subnetwork of the same network. The subnet portion of an IP address
must be the same for each node on the same subnetwork.
Assign in g Su bn et Ma sk s
Before you can determine subnet numbers, you first must determine
which bits of the node address will be used to contain your subnet
numbers.
The bits that you designate for subnet identifiers compose the subnet
mask. The subnet mask is configured with NMMGR. The remaining
part of the node address is used to identify the host portion of the IP
address.

Networking Concepts
Subnetworks
The following rules apply when choosing a subnet mask and an IP
address:
•
•
•
Although any bits in the node address can be used as the subnet
mask, Hewlett-Packard recommends aligning the subnet mask along
byte boundaries, adjacent to the network number.
Although standards allow subnets on the same network to have
different subnet masks, Hewlett-Packard recommends that you
assign the same subnet mask to all subnets on a network.
Do not assign an IP address where the network address and/or node
address bits are all off (all 0s) or all on (all 1s). Likewise, the subnet
address bits cannot be all 0s or all 1s.
To determine the subnet mask, you first need to estimate the number of
networks required and the number of nodes on each subnet. Allow
enough bits for both nodes and subnets, as described in example 1.
Example 1
Assume you are choosing a subnet mask for a class C network (three
bytes for network address, one byte for node address), and you need
four subnets with up to 30 nodes on each subnet. You will need to
reserve three bits for the subnet address (remember, all 0s and all 1s
cannot be used) and the remaining five bits for the node numbers as
Figu r e 2-1
Cla ss C Ad d r ess w ith Su bn et Nu m ber
The 30 nodes per subnet will require at least five bits of the node
5
portion of the IP address (30 <32, and 32=2 , therefore you need 5 bits).
This leaves three bits remaining in the node portion of the IP address
for use as the subnet identifier. Subnet parts of all 0’s or all 1’s are not
recommended because they can be confused with broadcast addresses.
3
Therefore, you can have up to six subnets (2 –2=6) when three bits are
used for the subnet identifier.
Example 2
An IP address on a class B network with an 8-bit subnet mask

Cla ss C Ad d r ess w ith Su bn et Nu m ber
Now, refer again to example 1. The subnet mask must indicate that
three bits of the node portion of the IP address will be used for the
subnet identifier. The subnet mask turns on (sets to 1) all the relevant
bits for its subnet scheme. The subnet mask for example 1 is shown
below. Note that the most significant three bits of the rightmost byte
are set.
Subnet Mask

Decimal
will need to know this information for NMMGR configuration. The
table shows the possible values of the rightmost byte of the IP address
for each of the subnets, given the criteria described in the example.
(Remember, an address of all 0s or all 1s is not valid).
Column 2 shows the values, in binary, of the six subnet addresses. Five
zeroes are shown in parentheses to indicate where the three
subnet-address bits are located in the byte. The equivalent decimal
value for each subnet address is shown in the third column. The fourth
column shows the range of possible values for the node address of each
subnet. The five rightmost bits make up the node portion, and the
range is the same for all subnets. By combining the subnet address with
the range of node addresses, the possible decimal values of the
rightmost byte are obtained and shown in the fifth column.
The table shows that subnets of 30 nodes each are possible given a
subnet mask of 255.255.255 224. This is derived from the column that
shows the range of possible values for the five bits that make up the
node portion of the IP address. The range for each of the six subnets
shows 30 possible values.

By looking at the binary values of two IP addresses, it is easy to tell if
nodes belong to the same subnet. If they do, all the bits that make up
the subnet mask will be the same between IP addresses in the subnet.
Take, for example, two IP addresses (in decimal and in binary) of
192.6.12.41 1100 0000 0000 0110 0000 1100 0010 1001
192.6.12.55 1100 0000 0000 0110 0000 1100 0011 0111
The subnet mask has already been defined as:

Because the mask has all bits except the five rightmost bits set to 1, all
bits except the five rightmost bits must match between nodes on the
same subnet. Because the two example IP addresses from subnet 1 do
match except for their five rightmost bits, they belong to the same
subnet.
NOTE
Subnet addressing can be used in internetworks (networks with
gateways).

Internetworks
In ter n etw or k s
Two or more networks of the same type or of different types can be
linked together to form an internetwork or internet. For example, if you
wanted to connect the nodes in a Point-to-Point network with the nodes
on a LAN, the combination of the two networks would be called an
internetwork. Creation of an internetwork allows any node on one
network to communicate with any node on another network that is part
of the same internetwork. Up to 256 individual networks can belong to
the same NS internetwork.
The divisions between the networks in an internetwork are called
network boundaries. Nodes in each network will have the same
network address (network portion of the IP address); however, each
network within the internetwork will have its own unique network
address.
The networks in an internetwork may be connected by a bridge or
router, or by HP e3000 systems configured as gateways.
Ga tew a ys
One method of joining networks in an internetwork is by using
gateways. An HP e3000 system can have up to 256 gateways (combined
number of full gateways and gateway halves).
F u ll Ga tew a ys ver su s Ga tew a y Ha lves
NS 3000/iX allows you to choose between connecting two networks with
a full gateway or connecting them with two gateway halves. A full
gateway is a node configured as a full member of two (or more)
networks for the purpose of passing information between the networks
to which it belongs. The node is considered a member of each of the
networks for which it is configured.
A node that is a gateway half is configured as a member of a network
and as a partner of another gateway half. A gateway half link that joins
two networks connects two nodes (a gateway half pair) by a
Point-to-Point link (NS Point-to-Point 3000/iX Network link). The
gateway half link and pair is not considered a network itself. Each of
the paired gateway halves is configured as a member of a different
network (the two networks to be connected) and as a gateway half on
the same gateway half link. Together, the two gateway halves function
as a full gateway.

Gateway configuration includes both identifying neighbor gateways in
each node’s configuration file and configuring gateway half NIs for
nodes that will serve as one half of a gateway half pair. These tasks are
described as follows.
Id en tifyin g Neigh bor Ga tew a ys
If you are including gateways in your internet configuration, you may
want to modify each node’s configuration file so that the node is aware
of all of its neighbor gateways (gateways on the same link). You
accomplish this during configuration of each network interface for
which you want to allow communications over the gateway. You will
find step-by-step instructions for identifying neighbor gateways in each
of the link configuration sections of this manual.
An alternative to identifying neighbor gateways in every node’s
configuration file is to configure a default gateway for the node.
Instructions for doing so are included in this manual.
The next pages show several examples of gateway configuration.

When using NMMGR to configure any node, you will be entering the
identities of all the neighbor gateways into the configuration of the
node. The following examples illustrate several gateway configuration

Address Resolution
Ad d r ess Resolu tion
Address resolution in NS networks refers to the mapping of node names
to IP addresses and the mapping of IP addresses to lower level
addresses (such as an X.25 address or a station address). Several
address resolution methods are available for you to use individually or
in combination with each other. You can configure these methods
according to the needs of your network.
The available address resolution methods are:
•
•
•
Domain name services.
Network directory.
Probe (and probe proxy) (LAN, 100VG-AnyLAN, and 100Base-T
only).
•
Address resolution protocol (ARP) (LAN, Token Ring, FDDI,
100VG-AnyLAN, and 100Base-T only).
Dom a in Na m e Ser vices
The domain name services are a mechanism for resolving node names
to IP addresses. They conform to an open networking standard and will
facilitate communications between HP e3000 systems as well as with
non-HP e3000 nodes.
To use the domain name services, you must assign a name, in
ARPANET standard format, to each system on the network or
internetwork. You configure this name on the NS Configuration screen
(see configuration chapters for details).
You will also need to create a set of ASCII files on each system which
contain the addressing information the system will need. Instructions
Once you have configured the domain name services, the network will
be able to access the node using its domain name and the domain name
service routines will resolve the domain name to the node’s IP address.
NOTE
Domain name services provide name to IP address resolution only. If a
lower level address is required for network communication (for
example, an X.25 address) you will need to configure the network
directory as well.

Netw or k Dir ector y
The network directory is a set of files that contain information used by
the node to communicate with other nodes in the internetwork.
You use NMMGR to perform the following network directory functions:
•
•
•
•
Add, modify, and delete entries in the directory.
Review and inspect directory information.
Merge a remote directory with a directory on the local node.
Automatically update directories on a group of remote nodes by
using a background stream job controlled from a central
administrative node.
information on configuring the network directory through NMMGR.
More information on merging directories and on central administrative
nodes is included in this chapter.
Wh en a Netw or k Dir ector y is Requ ir ed
A network directory must be configured in the following circumstances:
•
•
•
nodes running on X.25
nodes not using domain name services
nodes on a LAN network that do not support the HP-PROBE
protocol
The network directory of a node in a Point-to-Point network must
contain the IP addresses of all other nodes that you want the node to be
able to reach.
When configuring the network directory for a Point-to-Point network,
make sure that the IP address you enter in the network directory
matches the data in the mapping screens (path name
NETXPORT.NI.NIname.MAPPING.mapentry).
For nodes on an X.25 network, the network directory maps the X.25
address key to an IP address to allow a node to communicate within the
X.25 network. You must configure a network directory for nodes using
X.25.
P la n n in g th e Netw or k Dir ector y
There are two theories about how network directories should be
planned and configured on a network, as follows:
•
•
Centralized network directories.
Decentralized network directories.
36
Chapter2
Download from Www.Somanuals.com. All Manuals Search And Download.
Networking Concepts
Address Resolution
The centralized theory requires each node on the internet to have the
same network directory. This means that every node in the network
must have an entry in the network directory. The advantage to this is
that you update the network directory in one place, then copy it to the
rest of the world. The disadvantage is that network directories for large
internets are going to be large.
The recommended way to create and maintain your network directory
using the centralized method is to assign a single node as the central
administrative node. You configure the network directory on this node
and then copy it to all other nodes on the network. When the network
directory is updated, it is updated on the central administrative node,
then copied to the other nodes. This procedure decreases the possibility
of incompatible directories. You may want to assign a central
administrative node for each network or for the entire internet.
The decentralized theory suggests that each network directory be
configured individually on each node. The advantage to this is that you
can customize the network directory on each node for security purposes
using local and global entries. The network directory will also be
smaller because it will only contain entries for that particular node.
However, updates must be done manually on each node.
Cop yin g a n d Mer gin g Netw or k Dir ector y Files
The first time you configure the network directory, an entry for all
remote IP addresses must be added manually using the NMMGR
screens. After the first network directory is configured, you can use the
MPE STOREand RESTOREcommands to copy the network directory to
other nodes. (This is assuming you have adopted the centralized
method of network directory maintenance. If you use the decentralized
method, you must always use NMMGR to create and maintain the
network directory.)
NOTE
The network directory uses a KSAM file pair. Therefore, when copying a
directory, be sure to copy both the data file and the key file. The system
names the key file automatically using the first six letters of the
network directory file name appended with a K. For example,
NSDIRK.NET.SYSis the name of the key file associated with the data file
NSDIR.NET.SYS.
Once a network directory has been established on each node in the
internet, you can set up a job stream to automate network directory
updates. The MERGEDIRcommand is part of a maintenance interface
provided primarily to support the updating of directories using a batch
job. Using this method, a job or series of jobs can be scheduled at
regular intervals to copy and then merge remote directories into the
local-system directory. See the MERGEDIRand the MAKESTREAM
commands in Using the Node Management Services (NMS) Utilities.

P r obe a n d P r obe P r oxy
NS 3000 LAN, 100VG-AnyLAN, and 100Base-T NIs with the
IEEE 802.3 protocol enabled are able to make use of a proprietary HP
protocol called p r obe. Probe makes it possible for nodes on an NS
IEEE 802.3 LAN, 100VG-AnyLAN, and 100Base-T to communicate
without a network directory or domain names. A node can determine
connection information about a node on the same LAN by sending a
multicast probe request out on the network. The target node recognizes
its address in the probe request and sends an individually addressed
probe reply with the necessary connection information to the
requesting node. The probe request/reply mechanism is sufficient to
obtain connection requirements within a network.
If the nodes on that LAN are to communicate with other networks, at
least one node on the network must have a network directory. The node
with the network directory is called a p r oxy ser ver . By using the
probe protocol, a node without a network directory can multicast a
request for an internet address from the proxy server. For backup
purposes, you should designate at least two nodes to be proxy servers.
Ad d r ess Resolu tion P r otocol (ARP )
HP e3000 LAN, Token Ring, FDDI, 100VG-AnyLAN, AND 100Base-T
NIs are able to make use of a standard protocol called Address
Resolution Protocol (ARP). ARP provides IP address to station address
resolution. ARP is enabled when the Ethernet protocol or Token Ring is
enabled.
En a blin g P r obe a n d ARP
With the concurrent configuration of IEEE 802.3 and Ethernet on a
network, both the probe and ARP protocols are also enabled. Both
protocols broadcast requests to all nodes on the network to resolve the
address of a given remote node.
If you disable IEEE 802.3 on a LAN NI, you also disable the probe
protocol. Likewise, by disabling Ethernet, you disable the ARP protocol
associated with it. You cannot disable both of these protocols
simultaneously; at least one must be active to facilitate network
communications.

Network Design Questions
Netw or k Design Qu estion s
Ask yourself the following questions to make sure your design adheres
to the considerations mentioned above:
1. Are all of the nodes in the network within roughly 200 meters of
each other?
If so, consider connecting them with 100Base-T links, or ThinLAN
links with Ethertwist. For entry-level servers, choose ThinLAN since
that adapter will offload part of the CPU load.
2. Are all of the nodes in the network within roughly 550 meters of
each other?
If so, consider connecting them with ThinLAN 3000/iX links. The
maximum cable length for segments of ThinLAN 3000/iX cable is
185 meters, with a maximum of three segments connected by
repeaters.
3. Are all of the nodes in the network within roughly 1,500 meters of
each other?
If so, consider connecting them with ThickLAN (thick coaxial cable).
The maximum cable length for each segment of ThickLAN coaxial
cable is 500 meters, with a maximum of three segments connected
by repeaters.
4. Are all of the nodes in the network located within 2 kilometers of
each other?
If so, consider using FDDI/iX links. The maximum cable length for
each segment is 2 kilometers with a maximum network length of up
to 200 kilometers.
5. Are nodes located at remote sites? (For example, in different
buildings in the same city, or in different cities?)
If so, consider installing an X.25 network or a Point-to-Point network
using dial links or leased lines. Choose leased lines if you have a
critical need for clear transmission or if the volume of data to be
transmitted is relatively large.
Routers, switches, bridges and hubs are used to set up networks.
•
Routers are used to route packets between networks and subnets
based on the packets destination address.
•
•
Bridges are used to connect two LAN networks that are far apart.
Hubs are multiport repeaters, used to build or extend a LAN
network. New nodes can be added to the LAN without disrupting
the existing network.

Networking Concepts
Network Design Questions
•
To connect two networks that run on different protocol stacks, a
gateway is needed. A gateway does conversion between the two
protocols at every layer until the application layer.
6. Is the set of nodes you wish to connect composed of some nodes that
are in close proximity to one another (for example, in the same
building) and other nodes that are geographically distanced (for
example, in different buildings or different cities)?
If so, you may wish to use ThinLAN 3000/iX, Token Ring 3000/iX,
FDDI, 100VG-AnyLAN, or 100Base-T networks for nodes that are
located near one another and Point-to-Point or X.25 links for nodes
in different buildings or cities.
7. Will HP 9000s or other minicomputers need to be part of the
network?
If so, consider ThinLAN 3000/iX (or its ThickLAN option),
Token Ring 3000/iX, FDDI/iX, 100VG-AnyLAN, 100Base-T, or
X.25/iX System Access.
8. Do you need access to nodes on public or private X.25 networks?
If so, consider using DTC/X.25 iX Network Links.
9. Is a subset of nodes either geographically or organizationally
distanced from another subset of nodes?
If so, you may wish to establish a network boundary between them
in order to make them two separate networks joined by a full
gateway or router. Alternatively, you may want to use subnets to
divide one network into two or more physically distinct subnetworks.
10.If you must use a gateway half, is the partner-gateway half in the
same building or further away?
If the two gateway halves are in the same building, you can use a
direct connect link between them. If the two gateway halves are
further away, you will need to use a dial link.

P la n n in g for Nod e Con figu r a tion
This chapter describes how to complete node worksheets before you
start configuration. You will need to collect some information ahead of
time to complete these tasks.
The main purpose of the node worksheets is to determine the
information you will need to configure for each node during NMMGR’s
guided configuration. This information depends on the type of network
you have. For a description of the fields in these worksheets, see
It is recommended that you make copies of these worksheets and fill in
the parameter information, then use these worksheets to guide you
through configuration in NMMGR.
Node worksheets list only the fields you can configure during guided
configuration, which allows you to configure your nodes as quickly as
possible. For information on configuration parameters that are
available through non-guided configuration, see the NS 3000/ iX
NMMGR Screens Reference Manual.

Follow the steps listed here to enter data for this screen. Refer to
“Fields” subsection for detailed information about each field on the
screen.
Step 1. Verify that the correct configuration file name, backup configuration file
name, and network directory file name are in the appropriate fields.
Step 2. If you have assigned a write access password, enter it in this field. If
you are not using the password feature, leave this field blank.
Step 3. Press the [Open Config] key. If you are creating the configuration file for
the first time, NMMGR will ask you to verify creation. Press the
[Open Config] key again to continue.
Fields
configuration file name
The only configuration file name the system recognizes
for use by the network subsystem is
NMCONFIG.PUB.SYS. You can, however, create or modify
a configuration file using a different name and save it
as an offline configuration file. You can use offline
configuration files as a means of creating and storing
configurations that you want to use in the future or
that you are preparing for use on a different system.

Introductory Screens
Begin Configuration Process
When you are ready to use an offlin e con figu r a tion
file, rename it as NMCONFIG.PUB.SYSand reboot the
system. (Keep in mind that any file you use as a
configuration file must be successfully validated before
you try to use it.)
Backup configurationfile name
A backup file name must be specified whenever a
configuration file is opened or created. The default
backup configuration file name is
NMCBACK.group.account. The backup file will be
automatically updated with the contents of the
configuration file each time the configuration file is
successfully validated.
Network directory file name
A network directory must be configured in the following
circumstances:
•
•
•
nodes running X.25
nodes not using domain name services
nodes on a LAN network that do not support the
HP-PROBE protocol
The only network directory file name supported by HP
is NSDIR.NET.SYS. This file is part of a KSAM pair. A
key file is created at the same time as this data file. The
key file will automatically be named using the first six
letters of the network directory file name, appended
with the character K. For example, NSDIRK.NET.SYSis
the name of the key file associated with the data file
NSDIR.NET.SYS. If the name of the data file is less than
six letters long, then the entire file name would be
appended with a K.
Write access password
The password is an optional feature. If a password has
been assigned, you must enter it in the password field
to update the configuration file or the directory file. It is
still possible to open an existing file without using an
assigned password, but the file will be in read only
mode and NMMGR will not accept changes.
If a password has not been assigned, you should ignore
the password field.
If you want to assign a password for the system you are
configuring, see Using the Node Management Services
(NMS) Utilities.

Fields
Local node name
The local node name is the name by which the
HP e3000 computer is known in the network. The
format of a node name is
nodename.domain.organizationwhere the total
number of characters is 50 or fewer, and each field
contains 16 or fewer characters (alphanumeric,
underscore, or hyphens). The first character of each
field must be alphabetic.
The nodenameportion of each node name must be
unique within the node’s network. The
nodename.domainportion of each node name must be
unique within the internetwork. HP recommends that
all nodes on the network be assigned the same domain
and organization.
Assign meaningful node names. For example,
MKTG.BND.HPand LAB.BND.HPare meaningful names
for two nodes on the same network within
Hewlett-Packard. One node (MKTG.BND.HP) is used by
the marketing department. The other node
(LAB.BND.HP) is used by the lab. The domainfield is the
same because the nodes belong to the same network.
The organization field is the same because the nodes
belong to the same internetwork.
Are you using OpenView DTC Manager?
If you answer yes to this question, NMMGR assumes
you are using a PC to manage your system and takes
you to the corresponding set of screens when you
configure DTS. If you answer no, NMMGR assumes you
are using host-based network management and takes
you to a different set of DTS screens. You should
already have answered this question when you
configured DTS.
Do you have X.25 system- to-system or PAD connections?
If you answer yes to this question, NMMGR assumes
you are configuring X.25 connections and takes you to
the set of screens required to configure DTC X.25
Network Access Cards when you configure DTS. If you
answer no, NMMGR assumes you have no need to
configure X.25 connections and takes you to a different
set of DTS screens. You should already have answered
this question when you configured DTS.

You need not enter the following items as NMMGR will fill these in:
•
•
Class A, B, C
Leading zeros for the network and node portion of the IP address.
HP assigns the network portion (initial nine digits) of IP addresses
from ARPA Class C, though your addresses may also be of Classes A
or B. The complete formats are:
Class
A nnn xxx.xxx.xxx
B nnn.nnn xxx.xxx
C nnn.nnn.nnn xxx
Where: nnn= the network portion of the IP address and
xxx= the node portion of the IP address.
For Class C, the nodeportion of the IP address must be between 001
and 254.
If you are adding your NS 3000/iX node to an existing network, the
network portion of each node’s IP address should be the same. You will
have to find out what this is, and use it in the network portion of the IP
address of your NS 3000/iX node. Also, you will need to know the node
portions of the IP addresses of each of the nodes (usually they will be
numbered sequentially, such as 001, 002, and so on), so that you can
specify a unique node portion for the IP address of your node. If you
have a network map, it should provide a record of such items as the
node name and IP address of each node. If there is no record, and if you
want to find out each node’s IP address, you will have to issue the
following command (NM capability required) on each of the nodes:
NETCONTROL NET=NIname;STATUS
One of the lines of output from this command tells you what the
complete IP address is for that node; the last three digits are the unique
node portion of the class C address.
IP subnet mask
An IP subnet mask is specified in the
same format as an IP address. The
32-bit mask is grouped in octets
expressed as decimal integers and
delimited by either a period (.) or a
space. An IP mask is used when
configuring subnetworks. The mask
identifies which bits of an IP address
will be used to define a subnetwork. To
determine these bits, you first need to
estimate how many subnetworks and
nodes per subnetwork you need. See
details on deriving an IP subnet mask.

Proxy node
Establishing a proxy node is a way of
placing node name and address
mapping information in a single
location. If you are configuring an
internetwork or a network with
non-HP nodes, it may be easier to
update your configurations if you have
them located in a central place, that is,
the proxy node. On an internetwork,
the proxy node is usually a gateway. (It
is not necessary to configure a proxy
node if you have configured domain
on domain names.)
Link name
The link name can have up to eight
alphanumeric characters and the first
character must be alphabetic.
Physical Path of LANIC
The physical path number corresponds
to the slot location of a node’s local area
network interface controller (LANIC)
card. Recommended slot locations and
physical path calculations vary
according to the type of HP e3000
system you are running.
For the various platforms, physical
path syntax (examples only) look like:

IP address
The IP address is an address of a node on a network. An
IP address has two parts: a network portion and a node
portion. The n etw or k portion must be the same for all
nodes on a FDDI network; the n od e portion must be
unique for all nodes on a FDDI network.
There are two methods of entering an internet protocol (IP) address
within NMMGR:
1. Enter the fully qualified IP address (for example, Class C,
C 192.191.191 009).
OR
2. Enter only the network (nnn) and node (xxx) portions of the IP
address as four positive integers between 0 and 255 separated by
periods or blanks (for example, 15.123.44.98).
You need not enter the following items as NMMGR will fill these in:
•
•
Class A, B, C
Leading zeros for the network and node portion of the IP address.

HP assigns the network portion (initial nine digits) of IP addresses
from ARPA Class C, though your addresses may also be of Classes A or
B. The complete formats are:
Class A nnn xxx.xxx.xxx
B nnn.nnn xxx.xxx
C nnn.nnn.nnn xxx
Where: nnn= the network portion of the IP address and
xxx= the node portion of the IP address.
For Class C, the nodeportion of the IP address must be between 001
and 254.
If you are adding your NS 3000/iX node to an existing network, the
network portion of each node’s IP address should be the same. You will
have to find out what this is, and use it in the network portion of the IP
address of your NS 3000/iX node. Also, you will need to know the node
portions of the IP addresses of each of the nodes (usually they will be
numbered sequentially, such as 001, 002, and so on), so that you can
specify a unique node portion for the IP address of your node. If you
have a network map, it should provide a record of such items as the
node name and IP address of each node. If there is no record, and if you
want to find out each node’s IP address, you will have to issue the
following command (NM capability required) on each of the nodes:
NETCONTROL NET=NIname;STATUS
One of the lines of output from this command tells you what the
complete IP address is for that node; the last three digits are the unique
node portion of the class C address.
IP subnet mask
An IP subnet mask is specified in the same format as
an IP address. The 32-bit mask is grouped in octets
expressed as decimal integers and delimited by either a
period (.) or a space. An IP mask is used when
configuring subnetworks. The mask identifies which
bits of the IP address comprise the network and
subnetwork portion.
Link name
The link name can have up to eight alphanumeric
characters and the first character must be alphabetic.
Physical path of device adapter
The physical path number corresponds to the slot
location of a node’s FDDI device adapter. Recommended
slot locations and physical path calculations vary

Configure Neighbor Gateways
Con figu r e Neigh bor Ga tew a ys
You need to visit the next two screens only if you are configuring a
non-gateway node that is on the same network as a gateway. In this
case, the non-gateway node needs to know the identity of any n eigh bor
ga tew a y. Neighbor gateways can be either full or half gateways.
Gateways that are on the same network are called n eigh bor
ga tew a ys. A non-gateway node on a LAN, Token Ring, or FDDI
network may need to go through a neighbor gateway in order to send
messages to an entirely different network. (Two nodes are on the same
network if the n etw or k portion of their IP addresses are the same.) All
LAN, Token Ring, FDDI, 100VG-AnyLAN or 100Base-T nodes that are
on the same network as a neighbor gateway need to know the identity
of any neighbor gateways. When you configure a LAN, Token Ring,
FDDI, 100VG-AnyLAN, or 100Base-T node, you enter into its
configuration the identity of any accessible neighbor gateways that
share the same network. The identified gateways may be either full or
half gateways.
You may designate gateways as d efa u lt ga tew a ys. Messages for a
network will be routed to a default gateway if there is no gateway
configured for the destination network. The default gateway will then
attempt to locate the destination of the message.

to go through a neighbor gateway in order to send messages to an
entirely different network. (Two nodes are on the same network if the
n etw or k portion of their IP addresses are the same.) All Point-to-Point
nodes that are on the same network as a neighbor gateway need to
know the identity of any neighbor gateways. When you configure a
Point-to-Point node, you enter into its configuration the identity of any
accessible neighbor gateways that share the same network. The
identified gateways may be either full or half gateways.
You may designate one gateway as a d efa u lt ga tew a y. Messages for a

Configure Node Mapping
Con figu r e Nod e Ma p p in g
The screens discussed in the following pages allow you to configure
shared dial or direct connect and dial node mapping. These screens
allow you to specify routes to target (destination) nodes and to indicate
the priority of each route.
The number of mappings you enter depends on how many links are on
the node you are configuring.
Nod es Ha vin g Sin gle Lin k s
If you are configuring a node (call it Node A) that has only one
Point-to-Point link to a second node (call it Node B), you enter one route
name as the mapping to the adjacent node (Node B).
If there are additional nodes attainable beyond Node B, you would only
have to enter one more mapping: make up a route name, and then you
can indicate the additional (non-adjacent) nodes by specifying a

If you are configuring a node that has more than one Point-to-Point
link, you could ultimately have several paths to a non-adjacent
destination node. Hence, if this node has more than one Point-to-Point
link, enter a symbolic route name for every other destination node on
the network.
The route name is only used during configuration of this node, and you
do not have to repeat it when you configure other nodes.

Fields
Route Name
A symbolic name, up to eight alphanumeric characters,
that represents a route between the node you are
configuring and a destination node. The route name is
only used within the NMMGR program. It is most
useful when the node you are configuring has more
than one possible way of accessing a target
(destination) node. It identifies different routes to
target nodes and is not the actual target node name. It
is used because you may need a way to identify more
than one route to a target node. There should be at
lease one symbolic route name for routes to every other
destination node on the network unless you use the “@”
wildcard destination IP address.
To help keep track of routes, you can use the
destination node name as the route name. If you have
more than one route to a given node, you can name the
routes nodename1, nodename2, and so forth.
Destination IP Address
IP address of the target (destination) node for which a
route is being defined.
Priority
Number from 1 to 99 that indicates which route has
precedence (priority) over another when there are
multiple routes to a destination. A route to a
destination that has a higher priority will take
precedence over a route with a lower priority. This field
is the primary means of influencing the choice of route.

Fields
Node Name
Display only.
Network Interface (NI) name
Display only.
IP address
IP address is an address of a node on a network. An IP
address has two parts: a network portion and a node
portion. The n etw or k portion must be the same for all
nodes on an X.25 network; the n od e portion must be
unique for all nodes on an X.25 network.
There are two methods of entering an internet protocol
(IP) address within NMMGR:
1. Enter the fully qualified IP address (for example,
Class C, C 192.191.191 009).
OR
2. Enter only the network (nnn) and node (xxx)
portions of the IP address as four positive integers
between 0and 255separated by periods or blanks
(for example, 15.123.44.98).
You need not enter the following items as NMMGR
will fill these in:
•
•
Class A, B, C
Leading zeros for the network and node portion of
the IP address.

Configuring a X.25 Node
Configure an X.25 Network Interface
HP assigns the network portion (initial nine digits) of
IP addresses from ARPA Class C, though your
addresses may also be of Classes A or B. The complete
formats are:
Class A nnn xxx.xxx.xxx
B nnn.nnn xxx.xxx
C nnn.nnn.nnn xxx
Where: nnn= the network portion of the IP address and
xxx= the node portion of the IP address.
For Class C, the nodeportion of the IP address must be
between 001and 254.
If you are adding your NS 3000/iX node to an existing
network, the network portion of each node’s IP address
should be the same. You will have to find out what this
is, and use it in the network portion of the IP address of
your NS 3000/iX node. Also, you will need to know the
node portions of the IP addresses of each of the nodes
(usually they will be numbered sequentially, such as
001, 002, and so on), so that you can specify a unique
node portion for the IP address of your node. If you
have a network map, it should provide a record of such
items as the node name and IP address of each node. If
there is no record, and if you want to find out each
node’s IP address, you will have to issue the following
command (NM capability required) on each of the
nodes:
NETCONTROL NET=NIname;STATUS
One of the lines of output from this command tells you
what the complete IP address is for that node; the last
three digits are the unique node portion of the class C
address.
IP subnet mask
An IP subnet mask is specified in the
same format as an IP address. The
32-bit mask is grouped in octets
expressed as decimal integers and
delimited by either a period (.) or a
space. An IP mask is used when
configuring subnetworks. The mask
identifies which bits of an IP address
will be used to define a subnetwork. To
determine these bits, you first need to
estimate how many subnetworks and

nodes per subnetwork you need. See
details on deriving an IP subnet mask.
Link Name
The link name identifies a specific
DTC/X.25 Network Access card to be
used for X.25 system-to-system
connections. This link name must be
the same as the link name you entered
for this card when you configured your
DTCs. You may configure up to 11
links. (One link must be used for
loopback. Loopback will be
automatically configured during the
guided screen configuration.)
DTC Node Name
Card Number
The DTC node name is the fully
qualified nodename
(name.domain.organization) of the
DTC that contains the DTC/X.25
Network Access card with the
configured link name.
The DTC card number is the number of
the DTC/X.25 Network Access card in
the associated DTC. If the card is
contained in a DTC 48, the DTC card
number can be any number from 1 to 5.
If the card is contained in a DTC 16,
the card number must be 2.

Remote node name
You must enter the remote node name of each X.25
node into the network directory. Include entries for all
remote nodes and, if you want to be able to perform
loopback, the local node as well.
Remote IP address
Also in the network directory, you must enter the IP
Address of each node whose identity you have entered

Address key
The X.25 address key is the name of a remote node with
which your local node will be communicating.
Hewlett-Packard recommends that you make the name
be the node portion of the remote node’s name (where
its full name is node.domain.organization). You
must configure an X.25 address key for each remote
node with which your node will be communicating. You
have a combined maximum of 1024 X.25 address keys
in the SVC and PVC path tables. The X.25 address key
name must be eight characters or less and the first
character must be alphabetic. A default address key
called POOLallows any system to access the local
system even if the remote system’s address is not
configured. POOLcan also be used when level 3
programmatic access (NetIPC) provides an X.25
address.
Network Interface (NI) name

SVC or PVC Parameters
The parameters for assigning either SVCs or PVCs are
described in the following paragraphs.
For SVCs
Remote X.25 address
The remote X.25 address is the remote node’s X.25
address. This address is required for SVCs if you have
specified an X.25 address key. This address must be
15 digits or less.
Chapter 8

Configuring a X.25 Node
Configure an X.25 Network Interface
Facility set
The facility set name is a name for a set of X.25
connection parameters. The parameters are determined
by the type of X.25 network that you are subscribed to.
You can configure options in a facility set so that
specified options are available for every virtual circuit
or negotiated for each virtual circuit on a per-call basis.
This facility set will be used when a connection is made
from your node to the specified remote node or from the
specified remote node to your node. A Facility Set is
required for SVCs if you have specified an X.25 Address
Key. The facility set name must be eight characters or
less, and the first character must be alphabetic. You can
configure up to 128 facility sets.
To modify facility set parameters, enter a 5in the field
at the bottom of the screen and press the [Go To] key.
This will take you to the X.25 User Facility Sets screen.
From this screen you can create new or modify existing
user facility sets. See the NS 3000/ iX Screens
Reference Manual for more information.
Security class
The security class is the level of logical security you
want to have when a connection is made to or from the
specified remote node. A Security level is required for
SVCs if you have specified an X.25 Address Key. The
possible values are as follows:
• IO— Both incoming and outgoing calls are accepted.
This is the default value.
• IN— Only incoming calls are accepted from this
particular remote address. Outgoing calls will be
rejected.
• OU— Only outgoing calls are accepted to this
particular remote address. Incoming calls will be
rejected.
• LK— Entry is locked. No call is accepted, either
inbound or outbound.
For P VCs
Permanent VC number
The PVC Number identifies a permanent virtual circuit
(PVC) on the remote node. If you have entered a name
in the X.25 Address Key field and are configuring PVCs,
then you also have to enter a value for the PVC
Number.

Configuring a X.25 Node
Configure Neighbor Gateways
Con figu r e Neigh bor Ga tew a ys
Use the next two screens only if you are configuring a node that is on an
an X.25 network as a gateway. In this case, the local node needs to know
the identity of any n eigh bor ga tew a ys.
Gateways that are on the same network are called n eigh bor
ga tew a ys. A non-gateway node on an X.25 network may need to go
through a neighbor gateway in order to send messages to an entirely
different network. (Two nodes are on the same network if the n etw or k
portion of their IP addresses are the same.) If a node on the X.25
network is trying to access a node on a remote network, it needs to
know the identity of its neighbor gateways. When you configure an X.25
node, you enter into its configuration the identity of any accessible
neighbor gateways that share the same network. The identified
gateways may be either full or half gateways.
You may designate gateways as d efa u lt ga tew a ys. Messages for a
network will be routed to a default gateway if there is no specific
gateway configured for the destination network. The default gateway
will then attempt to locate the destination of the message.

This chapter describes how to plan and configure the interface between
one gateway half and another gateway half. Gateway halves is one of
the early technologies used to connect two separate networks. For
information on configuring a node as a gateway half, use this manual.
Gateways are rarely used since the introduction of routers and the
internet.
Configuring a node as a gateway half requires configuring two separate
network interfaces: one for the serial interface to the remote side of the
gateway half, and a second for the gateway half’s interface to its home
network (for example, a LAN or point-to-point network).
Before configuring a gatehalf, you should have already configured its
home network interface, according to instructions in other chapters of
this manual.
Screens unique to gateway half configuration are indicated by bold
boxed screens. [FUNCTION] denotes the function key used at a screen to
invoke the next screen on the screen flow.

A network directory is used by the node for internetwork routing. It is
one of several ways of specifying fixed/hardcoded addresses for specific
node names, in cases where dynamic name resolution cannot be used. It
is also used for specifying unique node names for a system which has
multiple interfaces. Each entry in a network directory consists of a node
name associated with an IP address, the network type, and an
additional address, if necessary. The network directory uses the
internet protocol (IP) address to transfer data between networks. See
directory concepts and for guidelines as to when you need to configure a
network directory.

Fields
Configuration file name
The only configuration file name the system recognizes
for use by the network subsystem is
NMCONFIG.PUB.SYS. You can, however, create or modify
a configuration file using a different name and save it
as an offlin e con figu r a tion file. You can use offline
configuration files as a means of creating and storing

(Keep in mind that any file you use as a configuration
file must be successfully validated before you try to use
it.)
Backup configurationfile name
A backup file name must be specified whenever a
configuration file is opened or created. The default
backup configuration file name is
NMCBACK.group.account. The backup file will be
automatically updated with the contents of the
configuration file each time the configuration file is
successfully validated.
Network directory file name
The only network directory file name supported by HP
is NSDIR.NET.SYS. This file is part of a KSAM pair. A
key file is created at the same time as this data file. The
key file will automatically be named using the first six
letters of the network directory file name, appended
with the character K. For example, NSDIRK.NET.SYSis
the name of the key file associated with the data file
NSDIR.NET.SYS. If the name of the data file is less than
six letters long, then the entire file name would be
appended with a K.
Write access password
The password is an optional feature. If a password has
been assigned, you must enter it in the password field
to update the configuration file or the directory file. It is
still possible to open an existing file without using an
assigned password, but the file will be in read only
mode and no changes will be accepted.
If a password has not been assigned, you should ignore
the password field.

Fields
Node name
The name of the node for which you want network
directory information. The node name field must
contain a fully qualified node name, in the form
nodename.domain.organization, when used to add,
modify, delete, or rename a node.
The node name field when used with the Prev Page
and Next Pagefunction keys allows you to browse
through a specified part of the network directory. You
can enter part of a node name in this field to designate
which node names you want displayed. For example, if
you enter the value NIK, and press the [Next Page]
function key, the list of nodes will begin with the first
matching node name, for example
NIKOLAI.FINANCE.IND, and continue through the rest
of the alphabet until all node names between the letters
NIKand Zare listed.
Global?
The global/local setting for node name. The acceptable
values are Yor N. When the Prev Pageand Next Page
function keys are used, only node names whose
global/local setting matches the value in this field are
displayed.
Entries can be configured as either global or local in the
network directory. Globa l entries (the default) can be
merged into other directories using the MERGEDIR
command. Local entries are not merged into other
network directories. The local entries are used for
configuring localized network directory entries, thus
providing a mechanism to restrict directory data from
being propagated throughout the network.
A situation where this type of restriction could be
useful is when you want to change the configuration for
users on a single host, but not for everyone else. You
can configure two network directory entries: one local,
used by host users, and one global, used by everyone
else when establishing connections to the host. For
example, suppose Node A sets up a new link to Node C,
but Node A does not want other nodes (already
connected to A) to know about Node C until the new
link is tested. Users on Node A can configure a local
entry, which contains information about the new link
not included in the global entry configured for users on
other nodes.
Other uses of local entries include restricting certain
nodes from communicating with the internet, or being
able to direct which way to access remote nodes
depending on your configuration of local entries. When

Fields
Transport services
These three fields describe the transport services that
should be configured in each path.
TCP
TCP must be Y(yes) for all nodes. The
default is Y.
Checksum
for TCP
The checksum setting indicates
whether checksumming is optional (N)
or required (Y) for TCP. If this field is
set to N, then the use of checksums is
not requested when communicating
with this node. If this field is set to Y
then checksums are used when
communicating with this node.
Checksumming is required for
communication to non-HP systems. The
default is N.
PXP
PXP must be Y(yes) for all nodes. The
default is Y.
Note that the selection of transport services here must match the
settings in the remote node’s configuration file. If the checksum enabled
field in the path NETXPORT.GPROT.TCPof this node is set to Y, then TCP
checksum field in the network directory should also be set to Y.
IP address One IP address should be entered for each network
interface configured on the remote node that is directly
reachable from this node. Each address must match an
IP address configured in the remote node’s
configuration file. The path of the screen in the
configuration file that contains IP addresses is
NETXPORT.NI.NIname.PROTOCOL.IP.

If you are planning to use the domain name resolver for name to IP
address resolution, you will need to configure a set of ASCII files on
each node that contain needed information. To configure these files, you
use any standard editor to modify existing sample files according to the
more information on domain names.
This chapter details:
•

•
How to modify the RSLVSAMP.NET.SYSfile and save it as
RESLVCNF.NET.SYSfor use as the domain name resolver.
How to modify the HOSTSAMP.NET.SYSfile and save it as
HOSTS.NET.SYSfor use as the domain name host file.
Other files you can configure to make additional information
available to the network.

Configuring Domain Name Files
Create or Modify the Resolver File
Cr ea te or Mod ify th e Resolver File
The resolver file (RESLVCNF.NET.SYS) is an initialization file for the
domain name resolver. It contains information needed by the network
to determine how to resolve a domain name to an IP address. This file is
read by the resolver routines the first time they are invoked by a
process.
To create the resolver file, perform the following steps:
Step 1. Copy the sample file, RSLVSAMP.NET.SYS, to RESLVCNF.NET.SYS.
Step 2. Modify RESLVCNF.NET.SYSusing any ASCII editor so that it contains
information about the name servers, domain, and search order for your
network. The keywords included in the file are described under “Fields.”
To modify an already existing RESLVCNF.NET.SYSfile, simply use your
editor to update and save the existing file.
Fields
Each entry in the resolver file consists of a keyword followed by a value
separated by white space. The keyword and its associated value must
shows an example of a resolver file. Comment lines start with a pound
sign (#).
domain
Enter the local domain name. Most queries for names
within this domain can use short names relative to the
local domain name. If the host name does not contain a
domain part, the root domain is assumed. If more than
one instance of the domainkeyword is present, the last
instance will override.
The domain name is composed of labels, with each label
separated by a period. Each label must start with a
letter or digit, and have as interior characters only
letters, digits, hyphens (-), or underbars (_). A domain
name may have any number of labels, but its total
length, including periods, is limited to 255 characters.
label[.label][...]
Domain names are not case sensitive.
search
The searchentry is optional and indicates the order in
which domains should be searched for host name
lookup. You should add a searchentry if users on this
system commonly try to connect to nodes in other
domains. The search list is limited to six domains with
a total of 256 characters. If more than one instance of
the searchkeyword is present, the last instance will
override.

Configuring Domain Name Files
Create or Modify the Resolver File
Resolver queries will be attempted using each
component of the search path in turn until a match is
found. Note that this process may be slow and will
generate a lot of network traffic if the servers for the
listed domains are not local. Note also that queries will
time out if no server is available for one of the domains.
nameserver Enter the IP address of a name server the resolver
should query. The address must be in dot format, with
leading zeros omitted and a period between each
NOTE
It is very important that you omit the leading zeros in the network
addresses that you enter in the domain name resolver files. If you enter
leading zeros here, the domain name resolver will interpret the
numbers as octal numbers.
You can list up to three name servers, but you must use a separate
keyword entry for each. If there are multiple servers, the resolver will
query them in the order listed. If no nameserverentries are present,
the default is to use the HOSTS.NET.SYSfile.
If you have no server, do not add any nameserverentries; the resolver
will immediately revert to the HOSTS.NET.SYSfile.
Errors in the resolver file will be silently ignored by the resolver
routines.

Configuring Domain Name Files
Create or Modify the Hosts File
Cr ea te or Mod ify th e Hosts File
The host name data base file, (HOSTS.NET.SYS), associates internet
addresses with official host names and aliases. This allows a user to
refer to a host by a symbolic name instead of an internet address.
When you have configured the name server, this file serves only as a
backup when the server is not running. In this circumstance, it is a
common practice that HOSTS.NET.SYScontains a few addresses of
machines on the local network.
To create the hosts file, perform the following steps:
Step 1. Copy the sample file, HOSTSAMP.NET.SYS, to HOSTS.NET.SYS.
Step 2. Modify HOSTS.NET.SYSusing any ASCII editor so that it contains
information about the nodes on your network.
To modify an already existing HOSTS.NET.SYSfile, simply use your
editor to update and save the existing file.
Enter a single line for each host, including the following information:
[internet address] [local host name] [aliases]
A line cannot start with a space. Items are separated by any number of
blanks and/or tab characters. A pound sign (#) indicates the beginning
of a comment.
Network addresses are specified in dot format, with leading zeros
omitted and a period between each grouping. (See example addresses in
Host names can contain any printable character other than a white
space, newline, or comment character.
NOTE
It is very important that you omit the leading zeros in the network
addresses. If you enter the leading zeros here, the domain name
resolver will interpret the numbers as octal numbers.

Ad d ition a l Dom a in Na m e Con figu r a tion Files
In addition to the resolver file and the host name data base, three other
files are available to allow you to configure additional information
about your network. Each of these files is provided in sample format in
the NET.SYSaccount. Each sample file contains an explanation of the
format for the data and a sample entry. The available files and their
functions are described as follows.
Netw or k Na m e Da ta ba se
The network name database, NETWORKS.NET.SYS, associates IP
addresses with official network names and aliases. This allows the user
to refer to a network by a symbolic name instead of an internet address.
To configure the network name database, modify the sample file
NETSAMP.NET.SYS.
P r otocol Na m e Da ta ba se
The protocol name database PROTOCOL.NET.SYS, associates protocol
numbers with official protocol names and aliases. This allows the user
to refer to a protocol by a symbolic name instead of a number. The
protocol number mappings are defined in RFC 1010 Assigned Numbers.
To configure the protocol name database, modify the sample file
PROTSAMP.NET.SYS(this is required for FTP use, starting in release 6.0).
Ser vice Na m e Da ta ba se
The service name database, SERVICES.NET.SYS, associates official
service names and aliases with the port number and protocol the
services use. Reserved port numbers 0 through 255 are assigned by
RFC 1010. To configure the service name database, modify the sample
file SERVSAMP.NET.SYS.

Configuring Logging
This chapter includes step-by-step instructions to help you perform the
following tasks:
•
•
•
•
Access the logging configuration screens.
Modify the logging configuration.
Enable users for individual logging classes.
Activate logging.
Logging is configured for the purpose of recording events such as errors
and console commands. You configure logging for each of the
subsystems of NS 3000/iX and for NS 3000/iX links. Each subsystem
includes different classes of events (such as internal errors). You can
record logging to a disk file for later analysis, to the system console so
that the system operator receives the messages, or both.
You can also display logging events at individual users’ list devices.
This may be valuable to allow the network manager to monitor NS
console activity from an alternate terminal. If you configure a logging
class so that logging is recorded to a user.account, the user will receive
logged messages any time there is an active session for that
user.account. (Take care if you enable users for logging; doing so can
place a strain on system resources.)
The guided configuration process configures logging for you using
defaults. You can also configure or modify the logging subsystem using
either guided or unguided configuration.

En a ble User s for In d ivid u a l Loggin g Cla sses
The logging screens described previously in this chapter make it
possible to completely configure logging for all subsystems by
traversing only seven screens. However, using these screens, it is not
possible to configure logging so that messages generated by specific
logging classes are sent to an individual user’s list device.
The following steps describe the method used to configure users to
receive logging messages. Using this method, you can create a
configuration that allows messages from a single logging class, or a set
of classes, to be sent to a user’s list device.
To do so, you access and update the Logging Configuration Class Data

Configuring Logging
Activate Logging
Activa te Loggin g
NetIPC logging is automatically activated at system start up. Link
manager logging and network transport logging are activated when you
initiate the network transport (NETCONTROL START). Network Services
logging is activated when the Network Services are initiated (that is,
when the NSCONTROL STARTcommand is issued).
Network Link logging is activated when the specific link is first started.
When you are changing a logging configuration for a specific subsystem,
the changes will normally take effect when you perform a SWITCHNMLOG
UPDATEcommand. In some cases, however, such as when no logging is
currently active, the subsystem may need to be deactivated and
restarted. The steps that must be taken for each subsystem are shown

Sta r t Lin k s a n d Ser vices
Sta r t Softw a r e Loop ba ck
Issue the following command (NM capability required) to start software
loopback:
NETCONTROL START;NET=loopbackNIname
This starts up the control process, the transport, and software loopback.
Note: when you use guided NMMGR to create any NI, a loopback
network interface (whose loopbackNInameis LOOP) is automatically
generated. The loopback NI must be started if you wish to perform local
loopbacks or to DSLINEto the local node, also some ARPA services need
loopback to be started.
Sta r t a Lin k
Issue the following command (NM capability required) to start a link:
NETCONTROL START;NET=NIname
This starts the link identified by the NI name. (If no previous
NETCONTROL STARTcommand was issued, then the control process and
transport are also started.) The NInameis the network interface (NI)
name that you supplied during NS configuration. You can start the link
before loopback if you want. Start other links as needed.
Sta r t a Host-Ba sed X.25 Lin k
If your network includes X.25 links and you are using host-based

Operating the Network
Test Network Services
Test Netw or k Ser vices
In order to test that you have successfully configured and brought up
your NS node, HP provides an NS validation test called
QVALNS.NET.SYS. QVALNSis a program which modifies a file called
TQVALNSand streams it as a temporary job (JQVALNS). The job purges
and creates various files, and then runs a program called NSTEST.
NSTESTtests the network services (VT, RFA, RDBA, and NFT).
To run the NS validation test, follow the step below:
Step 1. Run the NS validation test on your own node. This tests the software
loopback capability. Issue the following command, where nodeis the
node portion of your own node name:
RUN QVALNS.NET.SYS;INFO=node
Step 2. Run the NS validation test on another system on the same network.
Select a remote node on the network and make sure that the link and
the network services are up on the remote system by issuing the
following commands on that node (NM capability required):
NETCONTROL STATUS
NSCONTROL STATUS
If the link or network services have not been started, either pick
another node or start them.
Note the node name of the remote node (given in the last line of output
from the NETCONTROL STATUScommand). If you followed the
configuration steps in this manual, the second and third portions of the
node name (the domain and organization) should be the same as the
second and third portions of the local node.
Step 3. Run the NS validation test across the link by issuing the following
command at the local node, where nodeis the node portion of the
remote node name:
RUN QVALNS.NET.SYS;INFO=node

To shut down NS, issue the following commands (NM capability
required):
DSLINE @;CLOSE
NSCONTROL STOP
NETCONTROL STOP
The DSLINEcommand shown above closes connections for your session
only.
NSCONTROL STOPallows existing users to continue using the services
until they finish their current task but prevents new uses of the
services by these users or by new users. Therefore, the services are not
actually stopped until all existing users finish using them. You can use
NSCONTROL ABORTinstead if you wish to immediately terminate all use
of the services.
NETCONTROL STOPcloses all open connections. To determine if there are
any sessions still active, enter: NSCONTROL STATUS. If you do not want
to wait until existing users are finished with their current tasks before
you bring down the system, issue NSCONTROL ABORTand then
NETCONTROL STOP.
If a host-based X.25 link is started, you will also need to issue a
DTCCNTRLcommand to stop X.25 and PAD support for the DTC/X.25
Network Access card. Enter the DTCCNTRLcommand after the
NSCONTROL STOPand NETCONTROL STOPcommands. Enter the
command as:
DTCCNTRL DTC=dtcname;CARD=cardnumber;FUNC=function

MP E/V to MP E/iX Migr a tion
This appendix provides a quick overview of the planning and tasks you
will need to do to migrate an NS 3000 network from an MPE/V system
to an MPE/iX system. This appendix assumes that you are migrating
your network as a whole; that is, replacing all MPE V systems with
MPE/iX systems and maintaining the same basic network function.
The following topics are covered by this appendix:
•
•
•
•
Differences between NS 3000/V and NS 3000/iX networks.
An overview of migration tasks.
Guidelines for converting files.
Guidelines for reconfiguring a network.

MPE/V to MPE/iX Migration
Differences Between NS 3000/V and NS 3000/iX
Differ en ces Betw een NS 3000/V a n d NS 3000/iX
There are a number of differences between the way NS is implemented
on MPE V systems and the way it is implemented on MPE/iX systems.
These differences affect the network itself, some of the applications that
users may run over the network, and the command used to obtain
status information about the network. Since it is helpful to understand
these differences as you prepare to move an existing MPE V network to
MPE/iX, they are summarized below.
Netw or k
A number of the methods available for making connections to an
MPE V network are not available with NS 3000/iX. If your MPE V
network includes one of these you will need to modify your network
configuration before attempting to use the network on MPE/iX systems.
More information on the specific steps required to modify or remove
unsupported links or connections can be found later in this appendix.
The connection methods that are not supported on NS 3000/iX are:
•
•
•
Manual dial modems.
Asynchronous Network Link.
Bisynchronous link-level protocol.
In addition, while it is possible to access a DS/3000 node directly from
an NS 3000/V node, this capability is not supported on NS 3000/iX. A
user of an NS 3000/iX network who wants to access a DS/3000 node
must first access an MPE V NS node. This is because the DS/3000 code
that was included as a subset of the NS 3000/V code is not provided
with NS 3000/iX.
Con figu r a tion Files
NS 3000/V network configuration files are separated into two files, the
NMCONFIGfile, which contains link information, and the NSCONFfile,
which contains the transport configuration and other subsystems you
have purchased such as SNA.
NS 3000/iX systems have a single NMCONFIG.PUB.SYSfile that contains
information for the network transport, for NetIPC and link-level
logging, and also for the Datacommunications and Terminal Subsystem
(DTS). NMCONFIG.PUB.SYSalso contains information for any other
subsystems you have purchased such as SNA.

MPE/V to MPE/iX Migration
Differences Between NS 3000/V and NS 3000/iX
Ap p lica tion s Su p p or t
There are also differences in the implementations of NS 3000/V and
NS 3000/iX that will affect certain applications that users may
currently be running on your MPE V network. These differences are as
follows:
•
NS 3000/iX supports PTOP for HPDESK only.
On NS 3000/iX PTOP is not supported for applications other than
HPDESK. Network users who are running PTOP programs will
need to convert them to NetIPC/RPM or BSD programs before
running them on an NS 3000/iX network. Refer to the NetIPC
3000/ XL Programmer’s Reference Manual and the Using
NS 3000/ iX Network Services for more information.
•
Nowait I/O RFA is not available with NS 3000/iX.
Privileged mode programs that use nowait I/O Remote File Access
over an MPE V network will need to be modified before they can be
run on an NS 3000/iX network. Refer to the Using NS 3000/ iX
Network Services for more information.
Obta in in g Sta tu s In for m a tion
On MPE V systems the SHOWCOMcommand returns status information
about a communication device, and is used to determine line activity
and quality. This information is still available on NS 3000/iX, but is
accessed through a different command. Use the LINKCONTROL STATUS
command to access status information on NS 3000/iX.

MPE/V to MPE/iX Migration
Migration Overview
Migr a tion Over view
There are a number of steps that you must take to successfully convert
an MPE V network for use as an MPE/iX network. These tasks are
summarized below, and described in more detail in the remainder of
this appendix. Keep in mind that, depending on the needs of your
installation, you may need to perform additional tasks to complete your
migration. For example, if you are adding communication links that did
not exist on your MPE V network you will also need to configure those
new links.
Befor e You Sta r t
This guide provides an extensive overview of NS architecture and
networking concepts. It also furnishes configuration design checks,
planning worksheets and examples to aid you in organizing new
network configurations. You should be thoroughly familiar with this
material before you begin your migration.
File Migr a tion Ta sk s
There are two primary tasks you will need to perform to migrate your
network configuration files. These are:
1. Run the NMMGRVER utility on the old configuration files to convert
them to the current software version. (You will first need to install a
copy of all configuration files used for your NS 3000/V network to the
MPE/iX network). Refer to “File Conversion Guidelines” later in this
Appendix.
2. Run the NMMGR utility on the new configuration file(s) to make any
changes required due to the differences between NS 3000/V and
NS 3000/iX. Refer to “Reconfiguration Guidelines” later in this
Appendix.
Ad d ition a l Migr a tion Con sid er a tion s
This appendix does not discuss hardware migration considerations;
however, you will find a description of hardware components in this
manual. Additionally, details of hardware installation and
configuration can be found in the following manuals:

MPE/V to MPE/iX Migration
File Conversion Guidelines
File Con ver sion Gu id elin es
A file conversion utility called NMMGRVER.PUB.SYSallows you to convert
earlier versions of subsystems for use with the current version of Node
Management Services (NMS) by converting the files to an acceptable
format.
Wh en to Con ver t Files
If you have not successfully converted your files you will be notified that
conversion is necessary when you try either to run NMMGR or to
perform a NETCONTROLcommand. If you attempt to run NMMGR
against an unconverted configuration file you will receive the message:
Version mismatch found on specified subsystem. Please run
NMMGRVER. (NMGRERR 53)
If you attempt to perform NETCONTROLwhile using unconverted files
you will receive the following message at the console:
Bad CONFIG File Version
In either case you should stop your current activity and run the
NMMGRVER.PUB.SYSfile conversion utility on your configuration files.

Follow these steps to convert configuration files using NMMGRVER:
Step 1. Make a backup copy of the existing configuration files.
Step 2. Install a copy of the MPE/V NMCONFIGfile to NMCONFIG.PUB.SYSon the
MPE/iX system, and then install copies of any NSCONFfiles.
Step 3. Execute NMMGRVER.PUB.SYSby entering:
RUN NMMGRVER.PUB.SYS

MPE/V to MPE/iX Migration
File Conversion Guidelines
Step 4. The system will then prompt for the name of the configuration file to be
converted by displaying the message:
Fileset to be scanned?
You can then choose to end the conversion program by pressing the
[RETURN] key, or you can enter one of the following filesets:
filename [.groupname [.acctname]]
@ [.groupname [.acctname]]
@.@ [.acctname]
@.@.@
NMMGRVER searches for files of type nconfin the specified fileset. For
each file found, it asks:
OK to convert filename.groupname.acctname?
where filename.groupname.acctnameis the name of a configuration
file. Enter Yfor yes, or enter either Nor [RETURN] for no.
Step 5. NMMGRVER checks the configuration file to determine whether it is
an MPE/V or an MPE/iX configuration file. If it is an MPE/iX file the
conversion proceeds without further user input. If the file is an MPE/V
file, however, NMMGRVER prompts you for the type of MPE/V file you
are converting, as follows:
What is the type of this file?
1) MPE V NSCONF
2) MPE V NMCONFIG
3) skip this file
Enter a value between 1 and 3.
Enter the appropriate value.
Step 6. After each file is converted NMMGRVER will display the following
message:
FILE CONVERTED
Continue to enter either Y, N, or [RETURN] until you have converted all
files.
In the conversion process, NMMGRVER will merge the information
from each NSCONFfile accepted for conversion with NMCONFIG.PUB.SYS,
and create new (converted) NSCONFfiles. If you have converted more
than one NSCONFfile, you will need to choose the file that corresponds to
the network configuration you want, and rename it as the new
NMCONFIG.PUB.SYS. Choose the NSCONFfile that corresponds to the
network configuration you want to use as your NS 3000/iX
configuration.

MPE/V to MPE/iX Migration
File Conversion Guidelines
This new NMCONFIG.PUB.SYSfile contains your NS configuration in a
format acceptable to MPE/iX. You can now run NMMGR to configure
the DTS subsystem, and to perform any needed modifications to the NS
configuration. See “Reconfiguration Guidelines” later in this appendix.
Up d a tin g Fr om a P r eviou s MP E/iX Ver sion
Updating from an earlier version of MPE/iX at the same time migrating
from NS 3000/V to NS 3000/iX, you will need to make a choice between
reconfiguring Distributed Terminal Subsystem (DTS) and reconfiguring
the NS network. The choice is necessary because MPE/V versions of
NMCONFIG.PUB.SYSfiles do not include DTS configuration values.
The circumstances of the installation determine which configuration
values to preserve. If the NS network is complex, you may decide to
convert the existing MPE/V configuration files, and reconfigure DTS. In
this case you should follow the steps under “File Conversion
Guidelines” earlier in this appendix.
If, on the other hand, your DTS configuration is extensive, you may
decide to migrate your existing MPE/iX configuration files to the new
version of MPE/iX. You will then need to redo your NS network
configuration so that both the NS and DTS configurations are contained
in a single, valid, MPE/iX NMCONFIG.PUB.SYSfile. In any case, you will
need to reconfigure either NS or DTS if you are both updating MPE/iX
and converting from an NS 3000/V network to an NS 3000/iX network.

MPE/V to MPE/iX Migration
Reconfiguration Guidelines
Recon figu r a tion Gu id elin es
Once the MPE/V NS configuration files have been converted for use
with the MPE/iX version of NS, reconfigure your network to account for
the implementation differences between NS 3000/V and NS 3000/iX.
Run the NMMGR utility against the configuration file generated by the
file conversion process and perform the following reconfiguration tasks:
•
•
•
Configure the physical path of all links for your network. This
configuration consists of a channel number (ccc) and subchannel
number (sss) in the form ccc.sss. There is no channel or
subchannel associated with NS on MPE V.
Since the LAP-B protocol is the only point-to-point link-level protocol
supported on the MPE/iX computer, you must reconfigure links that
were configured as bisynchronous links on NS 3000/V as LAP-B
links, or remove them from the network configuration.
Configure the Distributed Terminal Subsystem (DTS) according to
the needs of your installation. Refer to Configuring Systems for
Terminals, Printers, and Other Serial Devices for instructions on how
to configure the DTS.
The above configuration tasks are a general summary of what you will
need to do to reconfigure your network to run on MPE/iX. You should be
aware that there are many changes to individual screens and screen
fields. Refer to this guide for information on individual screens and
screen fields.

NS X.25 Migration: NS 3000/V to NS 3000/iX
Differences Between NS 3000/V and NS 3000/iX
Differ en ces Betw een NS 3000/V a n d NS 3000/iX
The following paragraphs summarize differences between NS 3000/V
and NS 3000/iX. Make sure that you account for these differences that
could affect your network when migrating to NS 3000/iX. For
information on operating system migration, refer to the MPE/iX
Migration series.
Ha r d w a r e
Some NS 3000/V hardware components are not part of an NS 3000/iX
network, such as the ATP for terminal connections, and the INP for
network links.
On an NS 3000/iX network, the DTC provides connections for local or
remote terminals and serial printers. The DTC also provides MPE/iX
access to X.25 through a DTC/X.25 Network Access card. The
Datacommunications and Terminal Subsystem (DTS) LANIC on the
MPE/iX host is used for system-to-system X.25 connectivity.
Un su p p or ted Netw or k Con n ection s
Before migrating your network, identify any unsupported network
connections. The network connections that are not supported on
NS 3000/iX networks are as follows:
•
•
Manual-dial modems.
Asynchronous SERIAL Network Link and bisynchronous link-level
protocol. To ease migration, you can convert Asynchronous SERIAL
network links to the NS 3000/V Point-to-Point links which can be
converted to NS 3000/iX. Point-to-Point links use the LAP-B
protocol.
•
Connections to DS/3000 nodes. DS network services are not
supported on NS 3000/iX. If DS/3000 nodes are part of an existing
network, either migrate them to NS 3000/V or maintain NS 3000/V
connections to the DS/3000 nodes.
Con figu r a tion of Ter m in a ls a n d P r in ter s
On NS 3000/V networks, the SYSDUMPprogram is used to perform I/O
configuration which includes configuring terminals, printers, and other
I/O devices and drivers. On NS 3000/iX, terminals and serial printers
are configured on the host (using NMMGR) and on the OpenView
Windows Workstation (using the OpenView DTC Manager software).
For more information on configuration using your OpenView Windows
Workstation, read Using the OpenView DTC Manager.

NS 3000/iX can affect applications that users may currently be running
on the NS 3000/V network. These differences are:
•
NS 3000/iX supports PTOP for HPDESK only. Network users who
are running PTOP programs will need to convert them to
NetIPC/RPM programs before running them on an NS 3000/iX
network. Refer to the NetIPC 3000/ XL Programmer’s Reference
Manual and the Using NS 3000/ iX Network Services for more
information.
•
Nowait I/O RFA is not available with NS 3000/iX. Privileged mode
programs that use nowait I/O Remote File Access over an NS 3000/V
network will need to be modified before they can be run on an
NS 3000/iX network. Refer to Using NS 3000/ iX Network Services
for more information.
Obta in in g Device Sta tu s In for m a tion
On MPE V systems, the SHOWCOMcommand returns status information
about communication devices such as Local Area Network Interface
Controllers (LANICs). On NS 3000/iX systems, this information is
available with the LINKCONTROL...;STATUScommand.

NS X.25 Migration: NS 3000/V to NS 3000/iX
Differences in X.25 Support
Differ en ces in X.25 Su p p or t
There are differences in X.25 support between NS 3000/V and
NS 3000/iX which need to be considered when you migrate as described
in the following paragraphs.
1980 Ver su s 1984 CCITT
NS 3000/V supports CCITT 1980 and NS 3000/iX supports both 1980
and 1984.
Gen er a l Level 3 Differ en ces
In MPE V X.25, a Reset is sent to initialize or clear a Permanent
Virtual Circuit. In MPE/iX X.25, a Reset is not sent to initialize or clear
a Permanent Virtual Circuit.
MPE V X.25 has a timeout on an interrupt collision. MPE/iX X.25 does
not.
Level 3 Access w ith NetIP C
In addition to the X.25 features supported on NS 3000/V,
NetIPC 3000/XL provides the following CCITT 1984 features:
•
•
Fast select facility.
The capability of modifying and reading the facility field in call
packets.
•
A new option in IPCDEST(called the destination network address
option) allows you to directly specify an X.25 address or PVC number
instead of a remote node name. See the NetIPC 3000/ XL
Programmers Reference Manual for more information. If using this
feature, you can configure POOLas an X.25 Address Key with its
security option set to “O” (outbound) in the X.25 SVC Address Key
Paths screen to allow outbound calls to any destination address.
• IPCCONTROL request12, reason for error or event, on NS 3000/V
can return 14 (network shutdown), 15 (restart sent by local
network), 16 (level 2 failure), 17 (restart sent by local protocol
module), and 18 (restart packet received). IPCCONTROLon
NS 3000/XL only returns 10 (Clear), 11 (Reset), or 12 (Interrupt).
•
In NS 3000/V, IPCSHUTDOWNdoes not complete until a clear
confirmation arrives. In NS 3000/XL, IPCSHUTDOWNcompletes
immediately.
•
In NS 3000/V, IPCCREATErequires that the network name be padded
with nulls. In NS 3000/XL, IPCCREATErequires the network name be

NS 3000/iX
The procedures that follow are for updating (migrating) configuration
files from a node running NS X.25 3000/V Link to a node that will be
running NS 3000/iX release 2.0 or later. This conversion procedure can
be used with NS 3000/V NMCONFIGand NSCONFfiles for version V-delta 3
or later. When updating a node running NS X.25 3000/V Link, all
NS 3000/V LAN, Point-to-Point, or NRJ E as well as X.25 information
will be updated to work with MPE/iX.
NOTE
The procedures that follow assume that there is no existing
NS 3000/XL NMCONFIGfile.
Deletin g Secon d a r y NIs
If you are migrating from NS X.25 3000/V (release V delta 7 or later) to
NS 3000/iX release 2.2 or later, make a backup copy of your NS 3000/V
NSCONFfile. To migrate to NS 3000/iX release 2.2 or later, you must
delete the secondary NIs in the NS 3000/V NSCONFfile before you use
NMMGRVER to convert it.

Using NMMGRVER
Usin g NMMGRVER
To use the NMMGRVER utility to convert your NS 3000/V
configuration file to NS 3000/iX release 2.0 or later, proceed as follows:
Step 1. At the MPE/iX prompt, type: NMMGRVER.PUB.SYSand answer the
questions.
Step 2. Do either steps a through c or steps d through g.
If your NS 3000/V node had only an NMCONFIGfile (but no NSCONFfiles),
follow the instructions in steps a through c.
a . To convert the NMCONFIGfile enter the file name:
NMCONFIG.PUB.SYS.
b. Enter Yto proceed when prompted.
c. Select type 2for NMCONFIGtype file. The converted file will be saved
with the file name you entered. In this case it is NMCONFIG.PUB.SYS.
This is the only filename that the node will recognize as its
configuration file.
If your NS 3000/V node had one or more NSCONFfiles, follow the
instructions in steps d through g.
d . Merge your NS 3000/V NSCONFfile with the NS 3000/V NMCONFIG
file, and convert it for use with NS 3000/iX release 2.0 or later by
entering a file name, for example: NSCONF1.PUB.SYS.
e. Enter Y to proceed when prompted.
f. Select type 1for NSCONFtype file. NMMGRVER will merge the
contents of the existing NMCONFIGfile with the NSCONFfile you
specified. It will be saved in the NSCONFfile you specified. In this
example, NSCONF1.
g. If you converted more than one NSCONFfile, decide which one will be
the network configuration you want on the NS 3000/iX system.
Rename the file to NMCONFIG.PUB.SYS.
Up d a tin g X.25 XL System Access Pa r a m eter s
On the NS 3000/iX host, use NMMGR to change the following

PAD Access Migr a tion Ca tegor ies
The way you assign a PAD device depends on what the device is and
how it will be used. Asynchronous devices attached to DTCs can either
be configured with nailed or non-nailed logical device numbers on each
of the MPE/iX host systems to which they have access. The following
subsections describe the characteristics of nailed and non-nailed
devices.
Non -Na iled Devices
A non-nailed device is a session-accepting device that is not
permanently associated with an ldev number at configuration time.
When the user at such a device logs on to an MPE/iX system, an ldev is
assigned from a pool of ldevs set aside for this purpose at configuration
time. The device characteristics of the PAD devices must match the
non-nailed PAD terminal profile.
The association between a non-nailed device and the assigned ldev
exists only for the duration of the session. One advantage of the use of
non-nailed device connections is that configuration is simplified, since it
is not required that each non-nailed device be individually configured.
The host cannot make an outbound call to a non-nailed device.
Na iled Devices
A nailed device is one with a permanently assigned ldev. The
assignment is configured on the MPE/iX host system. Nailed devices
can be accessed programmatically through their ldev number. There is
an ldev-to-25-address mapping. The host can support both inbound and
outbound calls.
Con figu r a tion of Na iled Ver su s Non -Na iled Devices
Following are some points to remember when configuring nailed and
non-nailed PAD devices:
•
•
•
•
Printer must be nailed.
Terminals may be nailed or non-nailed.
Programmatic access requires a nailed device.
Logon access may be either nailed or non-nailed.

bay:
•
Login with appropriate system management capabilities and
prepare system for shutdown (e.g., terminate any active jobs or
sessions, etc.)
•
•
•
•
Issue a <ctrl-a> shutdown. Make sure the system is halted before
continuing.
When the system has shutdown completely, power off the system
by pressing the system off button. Unplug the system.
Open the system to gain access to the PCI backplane, if
applicable.
Select an empty PCI slot and remove the slot cover (if present).
3. Install the PCI 10/100Base-TX card:

•
Observe the antistatic precautions.
Record the serial number from the card, if present.
Grasp the card by its edges or faceplate with both hands, insert
the card into the slot, and press the card firmly into place.
•
Secure the card and retaining screws (if present). Reassemble the
system.
4. Attach the system to the network:
•
Attach the 8-pin (RJ -45) plug on your twisted-pair LAN cable into
the RJ -45 connector on the card. The same RJ -45 connector is
used for either 10 or 100Mbit/s operation.
•
Attach the free end of the cable to any unused port on the
appropriate hub or switch (or into a wall jack that is connected to
a hub or switch). Connect power to system. Set the hub or switch
speed and duplex mode. The PCI 10/100Base-TX card operates in
either full-duplex or half-duplex mode.

•
•
On the 100Base-T “link configuration” screen, fill in the
appropriate autonegotiation, speed, and duplex settings. (For
more detailed information on the various screens, see the
NS 3000/ iX NMMGR Screens Reference Manual.
Perform configuration verification and exit NMMGR.
6. Verify the installation:
•
•
Verify that the link starts successfully by starting a network
subsystem (e.g., NETCONTROL START; NET=LAN1) that uses the
newly configured link.
Check console messages to verify that the link connected
successfully. The link status can also be checked via the
LINKCONTROLcommand. The following is a sample output for a
successfully connected link:
:linkcontrol tslink;status=L
Linkname: LANLINK Linktype: PCI 100BT
Linkstate: CONNECTED
where “LANLINK” is the link name as configured in NMCONFIG
on the “link configuration” data screen.
•
•
Verify that the card’s Link LED is on. Note that the LED cannot
light unless the link software is also started.
Verify connectivity with a remote system, e.g., by issuing a “ping”
command via the NETTOOL or PING utilities, or by establishing
a remote VT session (after issuing an NSCONTROL START).
If the link could not be brought up and the remote connection
successfully verified, refer to the section on “Quick Troubleshooting
Tips”.

Notes on Manual Speed and Duplex Mode Configuration
Notes on Ma n u a l Sp eed a n d Du p lex Mod e
Con figu r a tion
Because this PCI 10/100Base-TX LAN card supports autonegotiation,
you should not normally need to manually set the duplex mode.
Sometimes you may need to manually set the duplex mode of the card
— for example, if the switch is operating at full duplex but does not
autonegotiate.
Full-duplex mode is most commonly found in switches rather than
hubs. It may be found in either 10 Mbit/s or 100Mbit/s switch devices.
Full-duplex mode may provide a throughput advantage under some
circumstances, but the degree of the advantage is
application-dependent.
The PCI 10/100Base-TX card support both half- and full-duplex
operation.
Ensure that the speed, duplex mode, and autonegotiation of the
associated switch are configured the same as in the NMMGR
configuration for the PCI 10/100Base-TX card. If the switch supports
autonegotiation on the ports connected to the cards, this should be
enabled as explained in “Notes on Autonegotiation and Autosensing.”
To manually set the duplex mode of the PCI card, refer to the link
configuration screen in the active NMCONFIG network configuration
file, using NMMGR to access the configuration data and make changes.

The PCI 10/100Base-TX/3000 product provides the means for
interfacing various types of HP e3000 systems to either a 10Base-T or
100Base-TX network. 100Base-TX is a subset of 100Base-T networking
defined by the IEEE 802.3u-1995 standard. 100Base-TX provides 100
Mbits/s data transmission over category 5 unshielded twisted-pair
(UTP) cable for which two pairs of wires in the cable are used — one
wire pair for receiving data, and one wire pair for transmitting data.
The same card port that supports 100Base-TX operation can also
support 10Base-T operation.
Autonegotiation is a mechanism defined in the IEEE 802.3u
specification whereby devices sharing a link segment can exchange
information while the link is being established and automatically
configure themselves to operate at the most efficient mode shared
between them.
Autonegotiation is like a rotary switch that automatically switches to
the correct technology such as 10Base-T or 100Base-TX or between
half- and full-duplex modes. Once the most efficient common mode is
determined, autonegotiation passes control of the link to the
appropriate technology, sets the appropriate duplex mode, and then
becomes transparent until the link is broken.
The following is the IEEE 802.3u-defined autonegotiation hierarchy for
resolving multiple common abilities for a 10/100Base-TX card:
•
•
•
•
100Base-TX full-duplex (most efficient)
100Base-TX half-duplex
10Base-T full-duplex
10Base-T half-duplex (least efficient)
For example, if both devices on the link support 10Base-T (half-duplex)
and 100Base-TX (half-duplex), autonegotiation at both ends will select
100Base-TX (half-duplex) instead of 10Base-T (half-duplex).
Many 100Base-TX devices on the market today such as hubs and
switches do not support autonegotiation. Either the speed and duplex
mode of the device are fixed (as is usually the case with hubs), or they
are often manually configured at the desired speed and duplex (as is
often the case for switches). However, switches that support
autonegotiation are becoming more commonplace
If the PCI 10/100Base-TX/3000 card is connected to a device, such as a
switch, that is autonegotiating, the PCI card will autonegotiate with
the device to mutually determine the highest possible speed and duplex
settings between them.

Notes on Autonegotiation and Autosensing
If the PCI 10/100Base-TX/3000 card is connected to a device that does
not support autonegotiation or a device that has autonegotiation
disabled, the PCI card will autosense the speed of the link and set itself
accordingly. The duplex mode of the card will be set to half-duplex in
this case. If you want the card to operate in full-duplex mode, you must
set it using the method described in “Notes on Manual Speed and
Duplex Mode Configuration” in this document.
The PCI 10/100Base-TX card will sense when the connection between
itself and a hub or switch on the other end of a link has been broken. If
a connection is made to another (or the same) device and
autonegotiation is enabled, the autonegotiation and autosensing
process will be done again automatically. Autonegotiation and
autosensing are also done whenever the interface is reset.

Quick Troubleshooting Tips
Qu ick Tr ou blesh ootin g Tip s
P r oblem :
Incomplete version information displayed when
:NMMAINT,78command is issued.
This indicates that the MPE/iX 7.0 software installation or update has
not completed successfully. Consult your HP software support
representative.
P r oblem :
When an attempt is made to bring up the link (e.g., via
a :NETCONTROL STARTcommand for a LAN using that
link), it does not connect successfully. Connection
failure messages are logged to the console or a
:LINKCONTROL linkname;STATUS=Lcommand
shows the link as “DISCONNECTED”.
This often suggests an incompatibility between the card’s speed and
duplex settings and the switch or hub settings. Make sure to review the
settings for autonegotiation, speed and duplex in the link configuration
data and make sure they are consistent with what the hub or switch
expects and supports. Bring the LAN down (:NETCONTROL STOPor
DTCCNTRL option 4) and back up again, to cause software to read the
new configuration. If you still cannot connect successfully, make sure all
the cables are securely connected between the card and the hub/switch
and that the card is properly seated. If that fails, consult your HP
support representative.
