SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
The 6A-IOM-29-4, 6A-IOM-29-4-IR, 6A-IOM-29-4-LR, 6A-IOM-39-1 and 6A-IOM-39-1-LR connectors use Class
1 Laser transceivers. Read the following safety information before installing or operating the 6A-IOM-29-4.
The Class 1 Laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop
eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user
adjustment. Class 1 Laser transceivers comply with the following safety standards:
•
•
•
21 CFR 1040.10 and 1040.11 U. S. Department of Health and Human Services (FDA)
IEC Publication 825 (International Electrotechnical Commission)
CENELEC EN 60825 (European Committee for Electrotechnical Standardization)
When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission
limit of all three standards. Class 1 levels of laser radiation are not considered hazardous.
LASER RADIATION AND CONNECTORS
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power
exiting the fiber (under normal conditions) is -12.6dBm or 55 x 10 -6 watts.
Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The
maximum radiance from the optical port (under worst case conditions) is 0.8 W cm-2 or 8 x 103 W m-2 sr-1.
Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases
eye hazard. When viewing the output optical port, you must remove power from the network adapter.

FIBER OPTIC PROTECTIVE CAPS
Caution READ BEFORE REMOVING FIBER OPTIC PROTECTIVE CAPS.
Cable assemblies and MMF/SMF ports are shipped with protective caps to prevent contamination. To avoid
contamination, replace port caps on all fiber optic devices when not in use.
Cable assemblies and MMF/SMF ports that become contaminated may experience signal loss or difficulty inserting
and removing cable assemblies from MMF/SMF ports.
Contamination can be removed from cable assemblies by
•
•
Blowing surfaces with canned duster (Chemtronics p/n ES1270 or equivalent).
Using a fiber port cleaning swab (Alcoa Fujikura LTS p/n ACT-01 or equivalent) saturated with
optical-grade isopropyl alcohol, gently wipe the end surface of ferrules first; then wipe down the
sides of both ferrules.
•
Blow ferrule surfaces dry with canned duster.
Contamination can be removed from MMF/SMF ports by
•
Using the extension tube supplied with canned duster, blow into the optical port, being careful not
to allow the extension tube to touch the bottom of the optical port.
•
Reconnect cable and check for proper mating. If problems remain, gently wipe out optical port with
a DRY fiber port cleaning swab and repeat step 1.
Caution To avoid contamination, replace port caps on all fiber optic devices when not in
use.

1 INTRODUCTION
Welcome to the SmartCell 6A000 User Guide. The SmartCell 6A000 ATM switch is a module that fits into the
SmartSwitch 6000 chassis. You can install as many as five SmartCell 6A000 switches into a SmartSwitch 6000 chassis
(using the 6C305-3 power supply). The module is hot swappable, meaning that you can install and remove it without
turning off or disconnecting the chassis. This manual will help you quickly and easily install and configure your
SmartCell 6A000 switch.
By performing the steps described in the first two chapters of this manual, your switch will be physically installed,
accessible on your Ethernet network, and running either an IP over ATM VLAN or an emulated Ethernet or Token
Ring LAN.
Subsequent chapters provide information about switch use, maintenance, and problem solving. These topics include
•
Managing the switch: backing up configurations, adding routes, creating PVC connections,
upgrading software, dealing with bandwidth, and controlling congestion
•
•
Working with the switch’s hardware components
Troubleshooting
Note
For detailed descriptions of SmartCell 6A000 console commands and their use,

2.3 INSTALLING THE SWITCH
The SmartCell 6A000 is hot swappable, meaning that you can install and remove it without turning off or unplugging
the SmartSwitch 6000 chassis. You can install as many as five switch modules in each chassis (using the 6C205-3
power supply). In this configuration, the SmartCell 6A000 modules provide up to 75 user ports. Modules should be
connected with inter-module trunks if traffic must cross between modules. Table 2-3 shows the maximum number of
LAN and ATM switch modules that can be installed in a SmartSwitch 6000 chassis.

2p›F A single 6C205-1 power supply (the older version of the 6C205-3) can support
only two SmartCell 6A000s within a SmartSwitch 6000 chassis. Three SmartCell
6A000s can reside within a SmartSwitch 6000 chassis that contains two 6C205-1
power supplies.
Follow the instructions below to install the switch module into the chassis. Refer to Figure 2-2.
s• Remove the metal blank that covers one of the empty slots in the chassis.
¢• Open the ejectors at the top and bottom of the switch module.
•• With the LEDs at the top, align the top and bottom of the SmartCell 6A000 with the tracks in the slot.
T• Slide the switch into the chassis. The switch module obscures the view of the tracks at the bottom of
the chassis, so be sure to look at that area as you begin to slide the switch into the chassis.
Q• Close the ejectors. The installation is complete.

3.1 CREATING AN IP OVER ATM VLAN
This section describes implementing IP over ATM on your SmartCell 6A000 switch. The following assumptions are
made:
•
•
•
The 6A000 switch will have a client on the IP over ATM VLAN
The ARP server will reside on the switch and correspond to the address of the switch client
All end nodes (computers, edge devices, and so on) support Switched Virtual Circuits (SVCs)
1. Log into the switch, either through the terminal port or through the Ethernet interface by telnet.
2. Create a client on the switch and assign it as the ARP server for the VLAN.
SmartCell ZX # add ipatmclient
ClientNumber(0) : 1
ServerType(NONE) : local < the ARP server is assigned to the switch client
ServerAddress() :
IPAddress() : 90.1.1.1
< IP address is for example only
NetMask(255.0.0.0) : 255.255.255.0
MTU(9180) :
< subnet mask is for example only
SmartCell ZX #
The example above creates a client on the switch, designates the client as the ARP server for the VLAN
(ServerType= local), and assigns the client an IP address and subnet mask.
Note
Note
The command add ipatmclientalways prompts you with a subnet mask that is
appropriate for the IP address. However, if necessary, you can change the subnet
mask to correspond to the strategy employed within your networks.
Never create an IP over ATM VLAN (or an IP over ATM client) with the same
subnet as the SmartCell 6A000 Ethernet port.

3. Enter the show clientcommand to make sure the client is operational and to obtain the 20-byte
ATM address of the ARP server. For instance, if you used the client number (client 1) from the
example in step 2, enter the following command.
SmartCell ZX # show client 1

4. Physically connect your end nodes and edge devices to the SmartCell 6A000 ports.
Note
Your end nodes do not need to be physically attached to the switch that contains
the ARP server. For example, an end station is connected to a 6A000 switch that
is connected through a route to the switch containing the ARP server . No special
configuration is needed for this end station to participate in the VLAN because the
end station automatically finds its path across the route to the ARP server and the
other VLAN members.
5. Configure the ATM interface or adapter for end nodes and edge devices. Typically, configuration
consists of designating IP over ATM as the protocol, assigning the device an IP address, and
specifying the 20-byte ATM address of the ARP server (the switch’s client address). For details on
6. As your end devices are configured and started, they register with the ARP server. You can test
whether your IP over ATM VLAN is functional by pinging from one end device to another.
To make certain that all end devices are registered with the ARP server, you can inspect the switch’s ARP table using
the show ipatmarpcommand. For example, if three end devices with IP addresses 90.1.1.2, 90.1.1.3, and 90.1.1.4 are
added to the VLAN, the following ARP table entries should exist:

You have completed the process for creating an IP over ATM VLAN. Continue to the next section for instructions on
creating an emulated LAN or go to Chapter 4, “Switch Administration,” for information about SmartCell 6A000
switch operations and maintenance.
3.1.1
ATM Addressing for IP over ATM
The SmartCell 6A000 provides a default format for ATM addresses used by IP over ATM. The default format is
constructed as follows:
netprefix + two zero bytes + IP address of the device (in hex) + a trailing zero byte

3.2 CREATING AN EMULATED LAN
This section describes the steps for implementing an Ethernet Emulated LAN (ELAN) on your SmartCell 6A000
switch. The following assumptions are made:
•
•
The SmartCell 6A000 switch will contain a client on the ELAN.
All end nodes (computers, edge devices, other switches, and so on) support the Well Known LECS
Address or can obtain the address of the LECS using ILMI.
•
All end nodes support Switched Virtual Circuits (SVCs).
Note
An ELAN comes pre-configured on SmartCell 6A000 switches. The ELAN name
is “ELAN000.” To use this ELAN, start the LECS, configure your end nodes and
edge devices to use this ELAN000, and then plug them into the SmartCell 6A000.

1. Enter the start LECScommand to activate LANE server services on this switch.
SmartCell ZX # start lecs
NOTICE - 'LECS' ***** LECS started *****
SmartCell ZX #
2. Create an ELAN on your SmartCell 6A000 switch by executing the add elancommand. The
following is an example.
SmartCell ZX # add elan
ELANNumber(0) : 1
<1 is used instead of the default, (0)
ELANName(ELAN001): Marketing <ELAN is named Marketing instead of the default, (ELAN000)
ConnectMethod(SVC):
ELANType(802.3)
Multipoint(YES) :
MTU(1516) :
<The default (Ethernet) is used
Distribute(PROXY) :
SmartCell ZX #
3. Create a client for the switch on the ELAN. For example, enter
SmartCell ZX # add laneclient
ClientNumber(0) :1
<One is used instead of the default, (0)
LanName(ELAN001) : Marketing < ELAN name is Marketing, not the default, (ELAN001)
ServerType(LECS) :
ServerAddress()
<No LANE server address is specified; see note below
IPAddress() : 90.1.1.1 < IP address and subnet mask are included only as examples
NetMask(255.0.0.0): 255.255.255.0
MTU(1516) :
SmartCell ZX #
Note
Note
The command add laneclientalways prompts you with a subnet mask that is
appropriate for the IP address. However, if necessary, you can change the subnet
mask to correspond to the strategy employed within your networks.
When you create a client, it automatically finds the LECS address using ILMI.
As the local client joins the ELAN, the following messages are sent to the Event log:
NOTICE - 'ZLESSRV' LES Join 39:00:00:00:00:00:00:00:00:00:14:41:80:00:20:D4:

Caution Never create an ELAN (or ELAN client) with the same subnet as the SmartCell
6A000 Ethernet port.

Note
While creating an ELAN client for the switch is not absolutely necessary, it does
provide management connectivity with the switch over its ATM ports (instead of
the Ethernet port). See Chapter 4, “Switch Administration” for information about
how to reach switches not directly connected to the Ethernet network.
5. Physically connect your end nodes and edge devices to the SmartCell 6A000 ports.
6. Configure the ATM interface or adapter for all end nodes and edge devices. Typically, configuration
consists of specifying LAN Emulation as the protocol, assigning the device an IP address that
corresponds to the subnet of the switch’s client, and indicating that you want the device to either
acquire the LECS address through ILMI or use the Well Known Address as the address for the
LECS. For details on the SmartCell 6A000 automatic addressing scheme for LANE, see
7. As each end device registers with the LES and BUS, messages are sent to the event log of the
SmartCell 6A000 containing the LECS. You can check connectivity by pinging between end nodes.
Note
Your ELAN is now operational. Additional ELANs can be created in the same way. See Chapter 4, “Switch
Administration,” for information about SmartCell 6A000 switch operations and maintenance.
Note
While it is possible for a single ELAN on the SmartCell 6A000 switch to support
multiple subnets, in general, switch performance is best (and management easiest)
when the “One-subnet-per-ELAN” rule is observed.

3.2.1
ATM Addressing for LAN Emulation
The SmartCell 6A000 provides a default format for ATM addresses used by LAN emulation. The default format is
constructed as follows:
netprefix + the MAC address of the device + a Selector Byte
Where the netprefix is constructed from
39 + nine zero bytes + the last three bytes of the switch’s MAC address
The Selector Byte specifies to whom the ATM address belongs.
00
01
02
= LEC
= LECS
= LES or BUS
00:20:D4:14:41:80
, then the 20-byte ATM address of the LECS is:
For instance, if the switch’s MAC address is
39:00:00:00:00:00:00:00:00:00:14:41:80:00:20:D4:14:41:80:01
Where
39:00:00:00:00:00:00:00:00:00:14:41:80
= netprefix
= the switch’s MAC address
= the Selector Byte indicating that this is the LECS
00:20:D4:14:41:80
01
Additionally, within both the LES and BUS addresses, the byte that corresponds to the last byte of the MAC address
is summed with the ELAN number. For example, the ATM address of the LESs on ELAN000, ELAN001, and
ELAN010 are
39:00:00:00:00:00:00:00:00:00:14:41:80:00:20:D4:14:41:80:02

LES for ELAN000 =
LES for ELAN001 =
LES for ELAN010 =
3.2.2
ELANs Across Multiple Switches
ELANs can exist within a single switch, or they can span multiple switches. When an ELAN spans multiple switches,
it’s important that all switches within the group use the same LECS. The general rule is: “Within an administrative
domain (a group of switches with related ELANs), there should be one and only one LECS.” For this reason, never
start the LECS on more than one switch within the administrative domain.
Note
If an uplink or end node does not support PNNI, or if its version of ILMI is
incompatible, it may be necessary to set up a static route between the device and
3.2.3
Switch Clients
It is important to understand the concept of SmartCell 6A000 switch client connections. A client connection is actually
a connection between the VLAN and the SmartCell 6A000 CPU; this CPU connection appears as if the switch is an
end station on the VLAN. The SmartCell 6A000 uses local clients to connect itself to the VLANs that it supports.

,6˜3¦F•˜":1˜"m=˜/"2'
%•F"›amV˜"m˜'h¤d"›F=˜/"2˜˜
This is analogous to a phone company that supports a communication system. Even though the phone company
maintains the circuits, a call to the phone company itself cannot be made unless the phone company has its own number
and connection on its own phone system. Similarly, VLAN membership (and the reachability) of a SmartCell 6A000
on any particular VLAN depends upon whether the SmartCell 6A000 has a local client connection for that VLAN.
Clients are created using the command add laneclientfor LAN emulation, and add ipatmclientfor IP over ATM.
For example, the following command adds a switch client to the ELAN elan1:
SmartCell ZX# add laneclient
ClientNumber(0)
LanName(ELAN001)
ServerType(LECS)
ServerAddress()
IPAddress()
: 1
: elan1
:
:
: 128.213.77.95
NetMask(255.255.0.0)
MTU(1516)
:
:
SmartCell ZX#
Prior to creating this local client connection, end devices could communicate with each other through elan1, but they
could not communicate with the SmartCell 6A000.

4 SWITCH ADMINISTRATION
This chapter contains software and hardware procedures that you might need to perform on your SmartCell 6A000
switch. These procedures include
•
•
•
•
•
•
•
•
Backing up switch configuration
Creating routes and connecting switches
Using switch events and alarms
Creating PVC connections
Managing switch traffic
Using low-level boot load switch commands
Upgrading switch software
Saving switch core dumps to a TFTP server
4.1 BACKING UP AND RESTORING SWITCH
CONFIGURATION
Once your SmartCell 6A000 ATM switch is up and running or you have made extensive changes to the configuration,
you should back up the switch configuration. If the flash RAM gets formatted or corrupted, you can restore the switch
configuration from the backup file.
Note
The backupcommand backs up only the configuration files. It does not back up
an image of the operating software.
To perform a back up or restore, you must have TFTP server software running on an end station that’s reachable by the
SmartCell 6A000. The backupcommand copies the configuration files on the switch to a directory specified by the
TFTP server software. Often, this directory is /tftpboot; however, it may be different with your TFTP server software.
Backup file names can be anything. Both the target backup directory and its file must exist and have appropriate read
and write permissions for the backup to complete successfully.
The backupcommand prompts you for the IP address of the TFTP server end station, the backup path, and the name
of the file within which you are saving the configuration. For example, if the IP address of the TFTP server end station
is 90.1.1.100, and you want to save the switch configuration in the file named config-1 under the directory /back_dir,
enter the following:
SmartCell ZX# backup switch
ServerIP() : 90.1.1.100
Path() : /back_dir/config-1
SmartCell ZX #

ATM Routing
Switch Administration
The switch stores the IP address of the TFTP server, the path, and the backup file name. The next time you enter the
backupor restorecommands, these values are presented as the default IP address and path. For example, when you
enter the restorecommand, the following display appears:
SmartCell ZX# restore switch
ServerIP(90.1.1.100) :
Path(/back_dir/config-1) :
SmartCell ZX #
Backup file is valid.
Restoring a backup file will completely replace any data stored in the flash.
Are you sure this is what you want to do?
Confirm(y/n)?: y
SmartCell ZX #
Note
You must reboot the switch for the restoreto take effect.
4.2 ATM ROUTING
The SmartCell 6A000 default routing protocol is PNNI version 1.0. PNNI provides automatic and dynamic
connectivity among all PNNI nodes within the same peer group. For purposes of interoperability, however, the
SmartCell 6A000 also supports these additional ATM routing protocols:
•
•
IISP — Use to connect with devices that do not support PNNI
UNI — Use to connect end stations (also to connect devices whose implementation of ILMI is
incompatible with the SmartCell 6A000)
Note
Both IISP and UNI routes are created and modified using the ATMRoutecommand.
The proper route type is determined by the SmartCell 6A000 through interface
signaling information.
4.2.1
Creating an IISP Route
Use the add ATMRoutecommand to create an IISP route that links the SmartCell 6A000 to a device that supports only
IISP routing. For example,
1. Physically connect port b2of the SmartCell 6A000 to the IISP device.
2. Enter show NetPrefixto determine the net prefix of port b2on the SmartCell 6A000:
SmartCell ZX # show netprefix b2
Port
==============================================================================
B2 39:00:00:00:00:00:00:00:00:00:14:41:80

3. Determine the address of the IISP device. (For this example, this could be a port address, we use
52:00:00:00:00:00:00:00:00:00:14:51:80)

The route to the IISP device appears on the last line (Route No. 7).
6. Create a route on the IISP device that refers to the net prefix
(39:00:00:00:00:00:00:00:00:00:14:41:80) of port b2on the SmartCell 6A000.
Note
For IISP routes to work with certain devices, ILMI may also need to be disabled
on the SmartCell 6A000. Use the set PortConfigcommand to disable ILMI on
the SmartCell 6A000 on a per-port basis.
IISP Routing Considerations
When creating routes between the SmartCell 6A000 (running PNNI) and IISP devices, the criteria that characterize
IISP connectivity still apply. To reach a SmartCell 6A000 within the PNNI domain, the IISP device must have a
configured route that points directly to a port on the target SmartCell 6A000. Conversely, there must be a SmartCell
6A000 that has a direct physical link (and a route over that link) to the IISP device. The following two examples
illustrate this point.
In Figure 4-1 Switch A is an IISP device connected to the PNNI domain through Switch B. Switch A contains an LEC,
which is a member of an ELAN whose LECS is on Switch C (within the PNNI domain). If the LEC on Switch A is to
make contact with the LECS on Switch C, Switch A must contain an IISP route (denoted by the dotted line) directly
to switch C. Furthermore, Switch B must contain a route to switch A over the physical link that connects the two
switches.

UNI Routes
Use the add ATMRoutecommand to create UNI routes. For example, connect an end station adapter (with MAC address
00:11:22:33:44:55) to port A2 of the SmartCell 6A000. If the adapter does not support ILMI or its ILMI is
incompatible with the SmartCell 6A000, you must create a static UNI route between the adapter and port A2 of the
SmartCell 6A000.
1. Enter the show netprefixcommand to obtain the netprefix of port A2
SmartCell ZX # show netprefix
PortNumber(ALL)

2. Reconfigure the adapter with an ATM address made from the netprefix of port A2 and the adapter’s
MAC address: 39:00:00:00:00:00:00:00:00:00:14:59:00:00:11:22:33:44:55:00.
3. Use the add ATMRoutecommand to create a static UNI route that specifies port A2 and the adapter’s

Route Metrics
Route metrics are assigned to routes using a metric tag (one of the input parameters for add ATMRoute). The metric tag
specifies a particular pair of incoming and outgoing metrics contained within a list of metrics. Metrics are created using
the add PNNIMetriccommand. Each metric pair specifies a set of values that describe a route’s Service Category, cell
rates, bandwidth, and administrative weight. Locally, metric values determine the behavior of the link, while
network-wide, PNNI’s Generic Call Admission Control (GCAC) assesses metrics when establishing calls.
In the following example, a metric pair is created (with metric tag of nine) that specifies CBR as the Service Category,
administrative weight of 200, Max Cell Rate of 1000 cells per second, and an Available Cell Rate of 750 cells per
second.
First, we create the outgoing member of the metric pair:

Administrative Weight and Parallel Routes
A route’s administrative weight defines its desirability to the PNNI routing service with regard to computing a path to
a particular location. The lower the administrative weight, the more desirable the route. For example, a route with
administrative weight 200 is considered a better route than one with the default weight of 5040. As a result, the
administrative weight provides a quantitative way to control which routes are favored for call set up.
The ability to control the PNNI routing service in this fashion allows for parallel routes into an IISP domain to be
weighted such that one route is designated as the default, while the other becomes the backup route. This
default/backup routing topology is typically used where a link to a particular domain requires a high degree of
reliability. If the default route becomes congested or reaches its bandwidth limit, the routing service can initiate load
sharing by routing additional calls through the backup route.
4.3 IP ROUTING
The SmartCell 6A000 switch provides limited IP routing. IP routing allows switches that are not connected directly to
Ethernet to communicate with an Ethernet-based network management system (NMS). The connection is made by
adding IP routes on the non-connected switches that specify a client on a connected switch as their gateway to the
Ethernet.

IP Routing
Switch Administration
Note
SmartCell 6A000 IP routing performance is inadequate for routing between
VLANs. If you need to create routes between VLANs on your SmartCell 6A000,
use a router equipped with an ATM interface. Consult Cabletron Customer
Support for recommended routers.
For example,
•
•
•
•
•
•
Switch SW1 and the NMS are on an Ethernet network with address 128.205.99.0.
The IP address of SW1's Ethernet port is 128.205.99.254.
The IP address of SW1's LANE client is 90.1.1.254.
The IP address of SW2's LANE client is 90.1.1.33.
SW2 is not physically connected to the Ethernet network.
SW2 is connected to SW1 through PNNI, and are both part of the same emulated LAN.
To reach SW2 with the Ethernet-based NMS, create an IP route that assigns SW1's switch client as SW2's default
gateway to the network 128.205.99.0. Enter the following on SW2 (see Figure 4-3):
SmartCell ZX # add route
DestNetIP() : 128.205.99.0 < address of the Ethernet network to reach

4.4 EVENTS AND ALARMS
The SmartCell 6A000 switch records and reports its operation in real-time through the use of events and alarms. An
event is an occurrence of a significant activity. For instance, a port going down or a client joining an ELAN are
examples of events. Alarms are a specific class of events defined as “events that the user needs to know about or attend
to immediately.” Alarms do not always indicate switch faults. Alarms may also be informational events. For instance,
“LECS Operational” is an example of an alarm that is not a switch fault, but is an activity that the user should know
about immediately.
4.4.1
Event Categories
Events are grouped into the following categories:
•
•
•
•
Critical — Impacts the entire switch, leaving the system unavailable or in a degraded state
Major — Impacts a feature of the switch, leaving the feature unavailable or in a degraded state
Minor — Impacts the system or feature, leaving it in a sub-optimal state
Informational — An occurrence of an activity that the user should know about
Both events and alarms are stored within circular memory buffers. When the buffers become full, older events and
alarms are overwritten by newer entries. Both events and alarms are stored in shared RAM. However, the 40 most
recent alarms are also stored in flash RAM. Storing these 40 alarms in flash RAM makes them persistent between
reboots of the SmartCell 6A000, and provides information about the state of the switch prior to reboot.

PVC CONNECTIONS
The SmartCell 6A000 supports Permanent Virtual Circuits (PVCs), both point-to-point and point-to-multipoint. Use
PVCs to connect devices (that do not support SVCs) to a switch’s local client. Also, use PVCs to make connections
through the SmartCell 6A000 between devices that support only PVCs.
Use point-to-point PVCs to connect one end node to another for two-way communication. Use point-to-multipoint
PVCs to connect a broadcast end node to a group of receiving end nodes; traffic is one way.
Note
PVCs use traffic descriptors to define their traffic characteristics. If you are

VCCMask combinations dictate what numerical values can be used for VPI/VCI pairs. Any VPI and VCI pairs that fit
the bit distribution of one of the indexed combinations can be used for defining a PVC. If the VPI and VCI values do
not fit one of the indexed combinations, the SmartCell 6A000 uses the closest matching indexed combination.
If you need to use values for VPI and VCI that do not fall within the range of one of the preconfigured indexed
combinations, use the set vccmaskcommand to replace one of the preconfigured combinations.
For example, change VCCMask indexed combination zero (0) from VPI = 0 bits and VCI = 12 bits to

4.6 TRAFFIC MANAGEMENT
This section describes how the SmartCell 6A000 manages bandwidth and congestion. It briefly describes console
commands that affect how the SmartCell 6A000 manages traffic. This section also provides guidelines for setting some
traffic control parameters.
Note
For information on troubleshooting traffic congestion problems, see Chapter 5,
“Troubleshooting.”
The SmartCell 6A000 has extensive abilities for managing the flow of traffic. Traffic management includes all
operations performed by the SmartCell 6A000 that ensure optimum switch throughput, where throughput is based on
rate of packet loss, available bandwidth, and traffic processing overhead. Under most conditions, the SmartCell 6A000
can efficiently and automatically manage switch traffic. However, if necessary, you can adjust the switch traffic
management parameters. For example, it might be necessary to adjust parameters for a port that carries a large amount
of CBR traffic or a very large number of simultaneous connections.
The SmartCell 6A000 provides console commands that affect traffic flow on a global, port, or category of service level.
These console commands affect switch traffic flow by controlling
•
•
•
•
•
Bandwidth allocation
Call Admission Control (CAC) policies
The service category for a connection
Buffer memory allocation
Threshold settings for anti-congestion routines
Caution Do not change traffic control settings unless you have expert-level experience
with ATM switching. Back up the switch configuration before making changes.
Also, make notes of the changes you make to the traffic control parameters.
4.6.1
Traffic Descriptors
Traffic characteristics of an ATM source are signaled through a set of traffic descriptors during connection
establishment. The SmartCell 6A000 uses traffic descriptors for resource allocation during call set up and guarantees
the Quality of Service (QoS) across the connection. The source traffic descriptor is a set of parameters that describes
the expected bandwidth utilization of a connection. You can set these parameters,
•
•
•
Peak Cell Rate (PCR)
Sustainable Cell Rate (SCR) and Maximum Burst Size (MBS)
Minimum Cell Rate (MCR) and Initial Cell Rate (ICR) — signaled through UNI4.0 signaling only
Traffic descriptors vary for each QoS. If a connection is bi-directional, a traffic descriptor has to be assigned to each
direction and need not be the same in both directions.
SmartCell 6A000 user data cells are classified according to the state of a cell loss priority (CLP) bit in the header of
each cell. A CLP 1 cell has a lower priority than a CLP 0 cell and is discarded first. Source traffic descriptors can
specify CLP 0 cell traffic, CLP 1 cell traffic, or the aggregate CLP 0+1 traffic.

A user-defined PVC must have user-defined traffic descriptors. For instance, if a video link over a PVC requires a
constant data flow of 5000 kb/s and a peak cell rate of 8000 kb/s, create a traffic descriptor for CBR traffic that specifies
5000 as the sustained cell rate and 8000 as the peak cell rate.

Call Admission Control Policy
Call Admission Control (CAC) policy defines the bandwidth allocation scheme used by the CAC when setting up
connections. The SmartCell 6A000 offers three schemes that can be set on a per-port, per-service class basis,
•
•
•
Conservative
Moderate
Liberal
Under conservative policy, the CAC allocates bandwidth closest to the requested bandwidth and QoS parameters.
Conversely, liberal policy causes the CAC to allocate the least amount of bandwidth. And the CAC under moderate
policy allocates intermediate amounts of bandwidth.
Depending on the type of traffic on your network, each of these CAC policies has its advantages. For instance, liberal
policy allows a larger number of connections over that of the conservative or moderate policy. Liberal policy assumes
that the traffic pattern of individual VCs does not overlap most of the time. For example, if VC1 and VC2 are created
under the liberal CAC policy, it’s assumed that the probability of both VCs sending large bursts of cells at the same
time is relatively low. On the other hand, conservative policy assumes that there might be a larger overlap of traffic
from different VCs, and provides each VC with bandwidth closer to the requested bandwidth. This higher bandwidth
provides a guarantee of quality for each VC.

The SmartCell 6A000 performs buffering using a shared-memory architecture. Buffer space is divided into queues for
each QoS. In turn, ports are allocated some portion of each of the QoS queues. This allocation is controlled on a
per-port basis by the porttrafficcongestioncommands.
Qos is defined on an end-to-end basis in terms of cell loss ratio, cell transfer delay, and cell delay variation.

Min and Max are thresholds set on a per-queue, per-port basis and are measured in cells (53 bytes). The Min threshold
is the amount of buffer space guaranteed to a call of a particular QoS on the corresponding port. The Max threshold is
the maximum amount of buffer space that a call of a particular QoS is allowed on the corresponding port.
QoS corresponds to the queues as follows:
•
•
•
•
Queue 1 — Constant Bit Rate (CBR)
Queue 2 — Real Time Variable Bit Rate (rt-VBR)
Queue 3 — Non-real time Variable Bit Rate (Nrt-VBR)
Queue 4 — Unspecified Bit Rate (UBR)
If calls of a particular QoS type are being dropped on a particular port, use the set porttrafficcongestioncommand
to raise the port’s queue Min threshold.
For example, to change both the Min and Max amounts of buffer space used for CBR calls on port a3, enter the
following:

EFCI, EPD, and RM Thresholds
To control switch congestion, the SmartCell 6A000 implements standard resource management cell (RM-cell)
marking, explicit forward congestion indicator cell marking (with backward RM cell marking), and early packet
discard (EPD). These congestion control schemes are triggered when the number of cells within shared memory
reaches user-definable thresholds. Use the switchtrafficcongestioncommands to view and set these thresholds.
For example, enter the show switchtrafficcongestioncommand.

EFCI thresholds are set on a per-QoS-queue basis, while EPD thresholds are set with respect to the total amount of
shared buffer used by all classes of service.
For most types of traffic, EPD triggering is tied to the low EPD threshold. Signaling traffic, however, is tied to the high
EPD threshold; this assures that signaling packets are discarded only when congestion is most severe.
Use the set switchtrafficcongestioncommand to change thresholds for EFCI and EPD and to enable or disable
RM and EFCI cell marking.

Along with EFCI and backward RM cell marking, the SmartCell 6A000 uses standard RM cell marking. The switch
discard threshold (show switchtrafficcongestion) corresponds to total shared buffer utilization and represents the
point at which the switch considers itself congested and starts marking RM cells.
Note
The switch discard threshold is not user configurable and is shown only for
information.
For information on troubleshooting congestion problems, see Chapter 5, “Troubleshooting.”

This section describes the low-level boot load commands. Boot load commands are used for setting switch start-up
behavior and for performing firmware downloads. Use the boot load commands to:
•
•
•
•
•
Set which copy of the boot load firmware is the default copy
Clear all configurations stored within the flash file system
Check boot load firmware version numbers

Accessing the Boot Load Prompt
Boot load commands are executed from the boot load prompt. The boot load prompt is not part of the switch console,
and is accessible only after a reboot and before the switch software is loaded. Consequently, the boot load commands
can be used only through a terminal connection.
Perform the following steps to gain access to the boot load prompt:
1. Connect a dumb terminal (or PC running terminal emulation software) to the RJ-45 terminal port on
the front of the SmartCell 6A000.
2. Enter the rebootcommand from the terminal.
3. Wait for the following message to appear:
“Press any key to exit to boot load prompt.”
4. Before the countdown reaches zero, press a key to access the boot load prompt. Notice that the boot
load prompt (=>) differs from the prompt used by the switch console.

Upgrading Boot Load Software
Two images of the boot load software reside in flash RAM. The two images are identified as boot load image 0 and
boot load image 1. Both boot load images can be upgraded by using a TFTP/Bootp server. However, an upgrade is
always written over the boot load image that is not currently running. This insures that if a boot load upgrade fails,
there is still one good boot load image to fall back on.
Follow the steps below to upgrade the switch boot load software.
1. Set up the TFTP/Bootp server software on a workstation.
2. Connect both the TFTP/Bootp server and the SmartCell 6A000 to your Ethernet network. Make sure
that the TFTP/Bootp server can be reached by the SmartCell 6A000 Ethernet interface.
3. Connect a dumb terminal (or PC running terminal emulation software) to the SmartCell 6A000
Terminal port.
4. Copy the SmartCell 6A000 boot load software image into the appropriate location on the
TFTP/Bootp server. (In this example, the software is copied to c:\tftpboot\images\boot.ima.)

Using the Update Firmware Command
You can upgrade the operating software of the SmartCell 6A000 while the switch is running its current software. This
procedure is known as a hot upgrade and is accomplished by the update firmwarecommand.
When the 6A000 switch is started (or rebooted), it copies its operating software from flash RAM to the CPU’s program
memory. When a hot upgrade is performed, the image in flash RAM is erased and replaced with the new software
image. While the upgrade is occurring, the switch continues to run its copy in program memory. When the switch is
rebooted, the new software image residing in flash RAM is copied into system memory and then run.
To use the hot upgrade feature, the SmartCell 6A000 must have network access to an end station running TFTP server
software. The SmartCell 6A000 operating software file must reside within the directory specified by the TFTP server
software. Often, this directory is /tftpboot. However, it may be different with your TFTP server software.
The following is an example of a hot upgrade:
SmartCell ZX # update firmware
ServerIP()
Path()
: 214.95.77.240
: luxor/server.ima
You are updating the code image in the flash.

2785K (2852012 bytes) received.
Flash update succeeded.
You will have to reboot for the new image to take effect.
SmartCell ZX #
Notice that the update firmwarecommand does not use Bootp to find the TFTP server. Instead, the update firmware
command requires that you specify the IP address of the TFTP server, the path to the image file, and the file name.
Unsuccessful Update
If the update firmwarecommand fails, DO NOT turn off or attempt to reboot your SmartCell 6A000 switch. In its
current state, the operating software normally stored in flash RAM is erased. The switch is functioning only because
it is running the image of the operating software that resides in volatile system memory.
If possible, determine why the update firmwarecommand failed. Common causes for failure are:
•
•
•
•
Incorrect path and file names
Improper permission settings on the directory containing the upgrade software

If the problem is corrected, enter the update firmwarecommand to continue with the upgrade process. However, if
you are unable to correct the problem, use the df(download flash) command and a TFTP/Bootp server to replace the
operating software on your SmartCell 6A000. Follow the procedure outlined below:
1. Set up TFTP/Bootp server software on a workstation.
2. Connect both the TFTP/Bootp server and the SmartCell 6A000 to your Ethernet network. Make sure
that the TFTP/Bootp server can be reached by the SmartCell 6A000 Ethernet interface.
3. Connect a dumb terminal (or PC running terminal emulation software) to the SmartCell 6A000
Terminal port.
4. Copy the SmartCell 6A000 operating software image into the appropriate location on the
TFTP/Bootp server.
5. Set up the TFTP/Bootp server tables (or equivalent file) with the SmartCell 6A000 MAC address
and IP address. You may also need to specify the path to the image file to be downloaded.
6. From the terminal connection, enter the rebootcommand.
7. When the following message appears,
“Press any key to exit to boot load prompt. “
stop the countdown by pressing any key. The boot load prompt (=>) appears on the terminal screen.
8. Enter the df scommand. The SmartCell 6A000 contacts the TFTP/Bootp server and downloads the
operating software into its flash RAM.

4.8 SAVING CORE DUMPS
The SmartCell 6A000 core dump feature allows you to specify a local Ethernet host where, in the event of a system
failure, the SmartCell 6A000 sends a copy of its memory. SmartCell 6A000 system memory is saved to two files, one
containing CPU memory (core_cpu), the other common memory (core_cmn). These files can then be sent to
Cabletron customer support for analysis.
Note
To use the core dump feature, the local Ethernet host must be running TFTP server
software, and you must have write access to the TFTP directory.

5 TROUBLESHOOTING
This chapter provides basic troubleshooting for diagnosing and fixing problems with VLAN, emulated LANs, and
ATM traffic congestion.
5.1 TROUBLESHOOTING IP OVER ATM
You have configured an IP over ATM VLAN, but your network applications are not working. Use these questions and
tests to help determine the cause of the problem.
1. Check for connectivity: Try pinging between end nodes and from the SmartCell 6A000 (using start
ping) to its end nodes. If you cannot ping, check physical connectivity (disconnected cable and so
on).
2. Check IP routes and addresses.
•
•
•
Use the show routecommand to check the SmartCell 6A000 route table.
-
-
-
Are the destination addresses correct for the specified gateways?
Are there any routing loops?
Are one or more of the destination addresses mapped to the wrong subnet?
Use show client(ARP server is on SmartCell 6A000) to check the local client.
-
-
-
Does the client have the correct IP address?
Is the subnet correct? Is the ATM address correct?
Is the server type correct?
Check end node configurations.
Are end nodes configured correctly?
3. Check ARP statistics.
-
•
Use show ipatmarp(if the ARP server is on the SmartCell 6A000).
-
-
Are there entries in the table?
Are the ATM addresses correct?
•
Use show clientarp(ARP server is not on SmartCell 6A000) to check local client’s ARP Table.
-
-
Are there entries in the table? If not, recheck client and end node configuration.
Are the ATM addresses correct?
4. Check ILMI, UNI routes, and PVCs (if applicable).
•
If using SVCs, use show ATMRouteto check whether static UNI routes are correct and whether
dynamic UNI routes are established and correct. If dynamic routes are incorrect or missing, try
creating static routes instead.
•
•
If using PVCs, use show pvcto check if PVCs connect the correct resources through the correct
ports.
If using PVCs, use show ipatmpvcto check if local switch clients are mapped to the correct end node
IP addresses.

5. If working through these questions does not solve the problem, contact Cabletron Systems Customer
Service. (See Appendix C, “Technical Support.”)
5.2 TROUBLESHOOTING LAN EMULATION
You have configured an Emulated LAN and your network applications are not working. Use these questions and tests
to help determine the cause of the problem.
1. Check for connectivity. Try pinging between end nodes. Ping from the SmartCell 6A000 (using
start ping) to its end nodes. If you cannot ping, check physical connectivity (disconnected cable
and so on).
2. Check IP routes and addresses.
•
Use show routecommand to check the SmartCell 6A000 route table.
-
-
-
Are the destination addresses correct for the specified gateways?
Are there any routing loops?
Are one or more of the destination addresses mapped to the wrong subnet?
•
Use show clientto check the SmartCell 6A000 local ELAN client.
-
-
-
-
Does the client have the correct IP address?
Is the subnet correct?
Is the ATM address correct?
Is the server type correct?
•
Check end nodes configurations.
Are end nodes configured correctly?
3. If the ELAN spans multiple switches, check the following:
-
-
-
Is the LECS address correct on all switches?
Can all switches reach the switch providing LECS support?
-
If using the Well Known LECS Address, are all switches correctly mapped?
4. Check the LECS database.
Use show lecselanto check the names and numbers of ELANs.
•
-
-
Are ELAN names correct?
Is the ATM address of the LES correct?
5. Check whether BUS is connected.
•
Use show busclientto check whether devices are registered with the BUS. If clients are registered,
check end node configuration. If not registered, check multi-point signaling.
•
Use set leselanto turn off multi-point signaling on a per-ELAN basis.
-
Do devices begin to register with the LES and BUS once multi-point signaling is turned off?
•
Check IISP routes to the switch containing the LES and BUS.
-
-
Are all IISP routes correct?
Does a new IISP route need to be added so devices can reach the LES and BUS?

Troubleshooting
TroubleshootingPNNILinks
6. If working through these questions does not solve the problem, contact Cabletron Systems Customer
Service. (See Appendix C, “Technical Support.”)
5.3 TROUBLESHOOTING PNNI LINKS
You have physically connected another company’s ATM switch with your SmartCell 6A000. Each switch supports
PNNI, but there is no connectivity between the two devices. Use the following procedure to diagnose and resolve the
problem.
Examine the link state on each switch (show PNNILinkon SmartCell 6A000).
•
If the link does not appear in the Link list, check the following:
-
Is the connecting port on each switch configured for PNNI? If no, configure both ports for
PNNI.
Note
On the SmartCell 6A000, use the show portconfigcommand to determine
whether the port is PNNI. If show portconfigdisplays autoConfigas the port
configuration, use the set portconfigcommand to disable ILMI and manually
set the port to PNNI.
-
Examine the VCC masks for each switch. Are the switches using compatible VPI/VCI pairs? If
not, adjust the VCC mask so that both switches use compatible VPI/VCI pairs.
•
•
If link state is “attempt,” check the following:
-
Is the PNNI peer group ID the same on both switches? If not, set both peer group IDs to the same
value.
-
Is the PNNI node ID the same for both switches? If not, set the PNNI node ID to the same value.
Especially check that the first two octets (peer-group level and lowest-level node) of the node
ID are the same for both switches.
If the link state is “2WayInside,” check the ATM route tables on each switch (show ATMRouteon
SmartCell 6A000).
-
If the switches are supporting end systems or have clients, does the net prefix of each switch
appear in the ATM route table of the other?
If no, check both switches for signaling and ILMI misconfiguration.
If yes, contact Cabletron Systems Customer Service.
5.4 TROUBLESHOOTING CONGESTION
If the bandwidth of your SmartCell 6A000 begins to decrease, and if connections are being lost or packets are being
dropped at a high rate, it’s possible that your switch is becoming congested. Congestion can occur on the port level,
the global switch level, or both levels.
If you suspect that your SmartCell 6A000 switch is experiencing congestion, follow the steps outlined below to
diagnose and resolve the cause of congestion.
SmartCell 6A000 User Guide 5-3

Troubleshooting Congestion
Troubleshooting
5.4.1
Diagnosing Congestion
1. Enter the show portstatscommand, and take the default of (all).
2. If cells are not being dropped on all ports, proceed to the “Port Congestion” section.
3. If cells are being dropped on all ports, the indication is global congestion. Proceed to the “Global
Congestion” section.
5.4.2
Global Congestion
1. Is the total cell drop rate equal to the Unknown VC cell drop rate?
•
•
If yes, the switch is improperly set up. Check the switch configuration.
If no, this indicates global congestion. Continue.
2. Set the porttrafficcongestionvalues to those recommended in the “QoS Queue Allocation
Guidelines” section. Has the congestion subsided?
•
•
If yes, you are done.
If no, continue.
3. Have you changed the EPD threshold?
•
•
If yes, replace it to the default setting. If congestion subsides, you are done.
If no, continue.
4. Enter the show cacinfocommand for each port. Is the allocated bandwidth small and is the traffic
mostly UBR?
•
•
If no, go back to step 4 and check next port.
If yes, continue.
5. Enter the show porttrafficcongestioncommand. Is the UBR queue Max threshold large?
•
•
If no, go back to 4.
If yes, continue.
6. Reduce the UBR queue Max threshold by a small amount, then wait a few minutes.
7. Enter the show portstatscommand, and take the default of all. Is the number of cells dropped
increasing for this port, and quickly decreasing for all other ports?
•
•
If yes, proceed to the “Port Congestion” section.
If no, continue.
8. Is the number of cells being dropped by all other ports decreasing somewhat?
•
•
If no, go back to step 6.
If yes, continue.
9. Enter the set caceqbwallocscheme command and set call admission control for this port to a more
conservative policy (moderateor conservative).
10. Go back to step 4 until all ports have been checked.

Troubleshooting
TroubleshootingCongestion
5.4.3
Port Congestion
1. Enter the show portstatscommand a few times, noting the value for cells dropped and unknown
VCs dropped. Is the difference for cells dropped equal to the difference for VCs dropped?
•
•
If yes, the switch is improperly set up. Check the switch configuration.
If no, this indicates port congestion. Continue.
2. Enter the show cacinfo command for this port. Note the bandwidth allocated for each Quality of
Service on this port.
3. For each class of service, enter the set porttrafficcongestioncommand. Set the Max threshold
to the value recommended in the “Quality of Service Queue Allocation Guidelines” section.
4. Have you performed step 3 for every class of service for this port?
•
•
If no, go to step 3.
If yes, continue.
5. Enter the set caceqbwallocscheme command for this port. Set call admission control for this port
to a more conservative policy (moderateor conservative).
6. Check VC statistics for this port using either the show pvc /dor show svc /dcommand, whichever
is appropriate.
7. If the port belongs to the high virtual channel link (VCL), read the forward stats. If the port belongs
to the low VCL, read the backward stats. If the port belongs to both high and low VCLs, read both
stats.
8. Is the number of cells received increasing?
•
•
If no, go step 6.
If yes, continue.
9. Convert allocated bandwidth (kb/s) to cells (48 bytes).
Bandwidth in cells = (1024 X Allocated Bandwidth) / 384
where 384 = 48 cells X 8
10. Is the Allocated Bandwidth less than the Cell Reception Rate?
•
•
If no, go to step 6.
If yes, this VC is misbehaving. Take appropriate action, for example, terminate the VC.

APPENDIX B AGENT SUPPORT
This appendix briefly describes the support provided for managing the SmartCell 6A000 using Simple Network
Management Protocol (SNMP).
B.1 MIB, SMI, MIB FILES AND INTERNET MIB
HIERARCHY
A MIB (Management Information Base) is the term used to represent a virtual store of management data on a device.
Given the structure of management data, it can be operated upon (retrieved, created or modified) using the SNMP
protocol. The structure of that data is defined using a subset of a notation called Abstract Syntax Notation (ASN.1).
This subset is called SMI (Structure of Management Information). A file containing the definition of that structure is
called a MIB file. To provide for a uniform naming convention for all MIBs, from all vendors, for all kinds of data, a
standard format is used. This format is a hierarchy and is termed the Internet MIB Hierarchy.
The MIB structure is logically represented by a tree hierarchy (see Figure B-1). The root of the tree is unnamed and
splits into three main branches: Consultative Committee for International Telegraph and Telephone (CCITT),
International Organization for Standardization (ISO), and joint ISO/CCITT.
These branches and those that fall below each category have short text strings and integers to identify them. Text
strings describe object names, while integers allow computer software to create compact, encoded representations of
the names. For example, the ZeitNet MIB variable znIpAtmClient is an object name and is also represented by the
number one.
An object identifier in the Internet MIB hierarchy is the sequence of numeric labels on the nodes along a path from the
root to the object. The object for the Internet Standard for MIB II is represented by the object identifier 1.3.6.1.2.1. It

In Figure B-2, the ZeitNet proprietary group is identified by 1.3.6.1.4.1.1295; its subgroup, called znProducts, is
identified by 1; and the first variable is znManagedObjects with a value of 2. Therefore, the object znManagedObjects
has an object identifier of 1.3.6.1.4.1.1295.2.
B.1.2
Relation Between Object Identifier and the Represented Value
In Figure B-3, the znLec object (representing Lan Emulation Client information) has an Object Identifier of
1.3.6.1.4.1.1295.2.3333.9.1.1. The znLecDDCount object representing the number of Data direct connections
maintained by one LEC (Lan Emulation Client) has a object identifier of 1.3.6.1.4.1.1295.2.3333.9.1.1.1.1. Querying

B.2 MANAGING THE SMARTCELL 6A000
Your SmartCell 6A000 must be IP reachable by the NMS before it can be managed. The default connection between
the SmartCell 6A000 and the NMS is the SmartCell 6A000 Ethernet interface. Use theshow SwitchConfigcommand
to find the IP address of the SmartCell 6A000. An NMS can use this IP address to reach the SmartCell 6A000 through
Ethernet. An NMS can also manage the SmartCell 6A000 through one of its ATM ports if the SmartCell 6A000 has a
client connection into a VLAN or emulated LAN.
Note that the SmartCell 6A000 itself, is not reachable through ATM until a client for the switch is created and
participates as a member of a VLAN or ELAN. Your NMS uses that switch client’s address to access and manage the
switch.
To create a client for the switch, use the add IPATMClientcommand for VLANs and add LANEClientfor emulated
LANs.
Use the set MyNmAddrcommand to tell the SmartCell 6A000 which interface to use when communicating with your
NMS. For detailed information about these commands, see the SmartCell 6A000/ZX-250 Reference Manual.
B.2.1
Console Commands that Affect the Agent
The following is a list of the console commands that affect the operation of the SmartCell 6A000 SNMP agent. For
detailed descriptions of these commands, see the SmartCell 6A000/ZX-250 Reference Manual.
•
•
•
•
Community: Sets the community strings for the SmartCell 6A000
TrapCommunity: Specifies the NMS to which traps are sent
MyNMAddr: Specifies the IP address through which the switch is managed
TrustedNMS:Specifies the IP address of the NMS allowed to perform the following commands:
- update firmware
- backup
- restore
- reboot
