Introduction to Hotwire DSL
Routers

What is a Hotwire DSL Router?
The Hotwirer DSL (Digital Subscriber Line) Router operates as an IP router
connecting a DSL link to an Ethernet network. This system provides high-speed
access to the Internet or a corporate network over a traditional twisted-pair
copper telephone line to the end user.
DSL Technologies Supported
Paradyne’s Hotwire DSL network supports the following types of technologies:
H
Hotwire IDSL (ISDN DSL) products provide IDSL multirate symmetric packet
transport and can operate over a connection with an ISDN repeater or digital
facilities. Data rates of 64 kbps, 128 kbps, or 144 kbps can be configured.
H
Hotwire RADSL (Rate Adaptive DSL) products are applicable for both
asymmetric and symmetric applications. The 1 Mbps symmetric operation is
ideal for traditional business applications while the 7 Mbps downstream with
1.1 Mbps upstream asymmetric operation provides added bandwidth for
corporate Internet access. RADSL products can also save line costs by
optionally supporting simultaneous data and voice over the same line.
H
Hotwire SDSL (Symmetric DSL) packet-based products provide high-speed
symmetric DSL services with bandwidth for business applications. These
products are configurable from 144 kbps up to 2.3 Mbps. This gives service
providers the opportunity to sell multiple services with a single product.

Introduction to Hotwire DSL Routers
Typical DSL Router System
DSL is a local loop technology that uses standard twisted-pair copper wire to
support high-speed access over a single pair of twisted copper wires. DSL
applications are point-to-point, requiring DSL devices at the central site and at the
end-user site.
The Hotwire DSL routers interoperate with the following types of Hotwire IP DSL
cards (at the DSLAM/GranDSLAM chassis) to deliver applications at high speeds
in support of packet services over a DSL link:
H
H
H
The Hotwire 8303 or 8304 IP IDSL Cards interoperate with two Hotwire IDSL
Routers:
— Hotwire 6301 IDSL Router with one Ethernet port
— Hotwire 6302 IDSL Router with a 4-port Ethernet hub
The Hotwire 8343 or 8344 SDSL Cards interoperate with two Hotwire
Symmetric DSL Routers:
— Hotwire 6341 SDSL Router with one Ethernet port
— Hotwire 6342 SDSL Router with a 4-port Ethernet hub
The Hotwire 8510, 8373, and 8374 IP RADSL Cards interoperate with the
Hotwire 6371 RADSL Router with one Ethernet port
The following illustration shows a typical Hotwire system with a Hotwire DSL
Router. All Hotwire DSL routers transport data. The Hotwire 6371 RADSL Router
can transport data and POTS simultaneously.

Introduction to Hotwire DSL Routers
Service Subscriber
The Service Subscriber is the user (or set of users) that has contracted to receive
networking services (e.g., Internet access, remote LAN access) for the end-user
system from an NSP (Network Service Provider). Service subscribers may be:
H
H
H
Residential users connected to public network services (e.g., the Internet)
Work-at-home users connected to their corporate intranet LAN
Commercial users at corporate locations (e.g., branch offices) connected to
other corporate locations or connected to public network services
The Hotwire DSL Router must be installed at the customer premises to provide
the end user with access to any of the above services.
NOTE:
If you would like more information on DSL-based services, applications, and
network deployment, refer to Paradyne’s The DSL Sourcebook. The book
may be downloaded or ordered through Paradyne’s World Wide Web site at

Accessing the DSL Router

Access Control to the DSL Router
The Hotwire DSL Router can be managed from an NMS using SNMP or from the
command line interface. There are two methods to access the command line
interface:
H
H
Local access at the DSL router through the Console port, or
Access by a Telnet session (controlled through the management interface at
the Hotwire chassis).
When a local console connection is first established, a login prompt appears. The
Hotwire DSL Router accepts only one login session at a time. The DSL Router is
configured at the factory with a default login ID and password. However, to
provide login security to the DSL system, configure a new login ID and password.
Levels of Access
There is one login ID and two levels of privileges on the Hotwire DSL system.
Your user account can be configured with one user name and different
passwords for:
H
Administrator. The Administrator has two levels of access to the DSL router.
— Administrator, non-configuration mode: Provides read-only capabilities.
This is the same level of access as Operator.
— Administrator, configuration mode: Provides complete write access to the
DSL router. However, MIB sets are done from the NMS vs. the command
line.
H
Operator. The Operator has read-only access to display device information
with no modification permission and no access to management functions.

Accessing the DSL Router
Changing Access Session Levels
H
You can change the Administrator access level by entering:
admin enable
This command provides Administrator access level privileges. The DSL
router will respond with a prompt to enter the password for Administrator
access.
H
You can end the Administrator access level by entering:
admin disable
This command results in ending the Administrator access level session. No
password is needed.
page 2-5 for further details on ending a session.
The Operator and Administrator have the same Login ID with different passwords
for their access level. To determine the level of access for a session, refer to
Local Console Access
The DSL router ships with the local console enabled. After login, the local console
can be disabled with the command console disable. After saving this change
and ending the session, there is no local access through the console port. Any
access must be through a Telnet session or the NMS.
NOTE:
Entering console disableresults in NO local access to the DSL router.
If you attempt to log in, you will receive an error message.
To determine via a Telnet session if a console is enabled, enter:
show console
The display returned for the show console command will be:
H console enabled– Command line management at the console is
available, or
H console disabled– No command line management is available at the
console.

Overview of DSL Router Configuration
The Hotwire DSL Routers support various customer premises distribution
networks that contain IP forwarding devices or routers, in addition to locally
attached hosts or subnets. The Hotwire DSL Router has an IP Routing Table that
contains IP address and subnet mask information.
The DSL router supports Internet Protocol as specified in RFC 791 and Internet
Control Message Protocol (ICMP) as specified in RFCs 792 and 950. The DSL
router acts as a router (or gateway) as defined in RFC 791.
Interfaces for the DSL Router
The Hotwire DSL Router has two interfaces:
H
DSL Interface
The Hotwire DSL Router interface type is determined by the model number:
— 6301 and 6302 are Hotwire IDSL Routers
— 6341 and 6342 are Hotwire SDSL Routers
— 6371 is a Hotwire RADSL Router
The DSL interface has a unique MAC address assigned before shipping.

Configuring the DSL Router
H
Ethernet Interface
— All DSL routers have an Ethernet interface with a unique MAC address
assigned before shipping.
— The Ethernet interface is a 10/100BaseT interface that automatically
negotiates the rate. If all attached Ethernet devices support 100BaseT,
the DSL router will default to 100BaseT. Otherwise, the DSL router
operates at 10BaseT.
— The DSL router can be configured for either DIX format or IEEE 802.3
format. When the DSL router is configured to use IEEE 802.3 format, the
DSL router uses SNAP encapsulation as specified in RFC 1042.
— The Hotwire 6302 IDSL and the 6342 SDSL Routers each have a hub
configuration with four Ethernet connectors. The hub acts as a bit-level
repeater. There is logically one Ethernet communications interface and
one single collision domain.
— The DSL router only accepts frames on the Ethernet interface with its
own MAC address or a broadcast or multicast MAC address.
Ethernet and DSL Interface Identifiers
The following are the naming conventions used for the Hotwire DSL Router
interfaces:
H
H
eth1 (or e0) – Ethernet interface name.
dsl1 (or d0) – DSL interface name.
Service Domain IP Address Assignments
H
H
Multiple Service Domains can be defined using network addresses and
subnet masks.
For both the DSL interface and the Ethernet interface, four Service Domain
IP Addresses and subnet masks can be defined.

Numbered DSL Interface
In this scenario, the hosts attached to the DSL router’s Ethernet interface are on
a different logical network than the core router. The DSL router is the next hop
router for the hosts. The upstream next hop router for the DSL router is the core
router.

Configuring the DSL Router
IP Routing
The DSL router uses destination-based routing for downstream traffic. An IP
Routing Table is maintained to specify how to forward IP datagrams downstream.
The DSL router is capable of supporting 32 entries in the IP Routing Table. This
table can be viewed by both Operator and Administrator access levels.
The DSL router uses source-based forwarding for upstream traffic to ensure that
packets are forwarded to the upstream router specified for the configured Service
Domain.
Refer to Chapter 4, DSL Router Configuration Examples, for further details.
Network Considerations
The DSL routers can be configured to function in a variety of network
environments. The following sections provide descriptions of some of the DSL
router features:

Configuring the DSL Router
Address Resolution Protocol (ARP)
Address Resolution Protocol, as specified in RFC 826, is supported in the DSL
router. The DSL router provides for a total of 265 ARP table entries. The timeout
for completed and uncompleted ARP table entries is configurable.
NOTE:
The DSL router does not process ARP requests and ARP responses on its
(Standard mode). See Routed vs. Bridged PDUs on page 3-10 for more
information. The operating mode (Standard or VNET) can be changed from
the DSL card without requiring any reconfiguration of the DSL router. If any
static ARP entries have been configured, they will remain in the database
and can be displayed with the show arpcommand. You can create static
ARP entries regardless of the current operating mode.
The Command Line Interface provides the ability to:
H
H
H
H
Create up to 64 static ARP table entries to be retained across power cycles.
Display the ARP table.
Delete ARP table entries.
Display and delete automatically added static ARP table entries by the DHCP
(DHCP) Server on page 3-7.
Proxy ARP
The DSL router supports Proxy ARP. Proxy ARP responses are based on the IP
Routing table contents. The IP Routing table must have an entry for every host
that is reachable on the Ethernet interface, including hosts for which the DSL
router will not forward packets because of IP filters. If an ARP request is received
on one interface for an IP address that is reachable on the other interface, the
DSL router will respond with its own MAC address.
NOTE:
The Proxy ARP option is not available on the DSL interface when the DSL
Bridged PDUs on page 3-10 for more information.
The Command Line Interface provides the ability to enable and disable Proxy
ARP for each interface.
NOTES:
— When Basic NAT is enabled, the DSL interface (dsl1) must have Proxy
ARP enabled if the dsl1 interface address is part of the Basic NAT global
IP network address.
— Proxy ARP and NAPT cannot be enabled at the same time.

Configuring the DSL Router
Network Address Translation (NAT)
Network Address Translation is used when a private network’s internal IP
addresses cannot be used outside the private network. The IP addresses may be
restricted for privacy reasons or they may not be valid public IP addresses.
The DSL router provides NAT as described in RFC 1631 The IP Network Address
Translator (NAT). NAT allows the private (local) hosts to transparently access
public (global) external IP addresses.
Two variations of traditional NAT are supported:
H
H
Basic NAT
Network Address Port Translation (NAPT)
NOTE:
Basic NAT and NAPT cannot be enabled at the same time.
Basic NAT
Basic NAT allows hosts in a private network to transparently access the external
network by using a block of public addresses. Static mapping enables access to
selected local hosts from the outside. Basic NAT is often used in a large
organization with a large network setup for internal use and the need for
occasional external access.
Basic NAT provides a one-to-one mapping by translating a range of assigned
public IP addresses to a similar-sized pool of private addresses (typically from the
10.x.x.x address space). Each local host currently communicating with a external
host appears to have an unique IP address. Up to 256 IP addresses can be
allocated for use with Basic NAT.
Network Address Port Translation (NAPT)
NAPT allows multiple clients in a local network to simultaneously access remote
networks using a single IP address. This benefits telecommuters and SOHO
(Small Office/Home Office) users that have multiple clients in an office running
TCP/UDP applications. NAPT is sometimes referred to as PAT (Port Address
Translation).
NAPT provides a many-to-one mapping and uses one public address to interface
numerous private users to an external network. All hosts on the global side view
all hosts on the local side as one Internet host. The local hosts continue to use
their corporate or private addresses. When the hosts are communicating with
each other, the translation is based on the IP address and the IP port numbers
used by TCP/IP applications.

IP Options Processing
The NAT and NAPT functions handle and process the IP datagrams with options
set as described below. No command is available to set IP options.
The DSL Router does not process (and drops) any IP datagrams with the
following IP options:
H
Loose source and record route (type 131)
Strict source and record route (type 133)
Security (type 130)
H

Dynamic Host Configuration Protocol (DHCP) Server
The DSL router provides a DHCP Server feature as specified in RFC 2131,
Dynamic Host Configuration Protocol, and RFC 2132, DHCP Option and BOOTP
Vendor Extensions. DHCP is the protocol used for automatic IP address
assignment.
DHCP setup considerations:

DHCP Relay Agent
The DSL router provides the capability of serving as a DHCP Relay Agent, as
specified in RFC 2131, Dynamic Host Configuration Protocol. The DSL router
provides the capability to enable and disable the DHCP Relay Agent and to
configure the IP address of the DHCP server to which the DHCP requests are to
be forwarded.
The DHCP server assigns an IP address to the end-user system. When DHCP
Relay is enabled, it is possible to limit the number of DHCP clients. The DSL
router’s IP Routing table and ARP table are automatically updated. The DHCP
relay agent in the DSL router should be used when there is a DHCP server
upstream in the service domain. DHCP relay agent setup considerations:
H
H
H
H
H
DHCP server IP address must be configured.
DHCP relay must be enabled.
The number of DHCP clients can be limited to 1—256.

Security
The DSL router offers security via the following:
H
H
IP Filtering – Can be enabled or disabled.
Land Bug/Smurf Attack Prevention – Always present.
IP Filtering
NOTE:
All Hotwire DSL Router filters are configured on the Hotwire DSL card.
By default, filtering is disabled on the Hotwire DSL card for the DSL router.
If enabled, filtering provides security advantages on LANs by restricting traffic on
the network and hosts based on the IP source and/or destination addresses.
IP packets can be filtered based on:
H
H
H
H
H
Destination IP Address
IP Protocol Type
Source and Destination Port Number (if applicable)
Source IP Address
TCP Filter (prevents the receipt of downstream TCP connect requests)
NOTE:
If the Source IP Address filter is enabled on the Hotwire card and an
IP address is assigned to the DSL interface, there must also be an entry
configured in the Hotwire Client Table for the DSL interface’s IP address.
For more information about IP filtering, see the Hotwire MVL, RADSL, IDSL, and
SDSL Cards, Models 8310/8312, 8510/8373/8374, 8303/8304, and 8343/8344,
User’s Guide.
Land Bug/Smurf Attack Prevention
Land Bug and Smurf Attack prevention are enhanced firewall features provided
by the DSL Router:
H
Land Bug – The DSL router drops all packets received on its DSL interface
or Ethernet interface when the source IP address is the same as the
destination IP address. This prevents the device from being kept busy by
constantly responding to itself.
H
Smurf Attack – The DSL Router will not forward directed broadcasts on its
DSL and Ethernet interfaces, nor will it send an ICMP echo reply to the
broadcast address. This ensures that a legitimate user will be able to use the
network connection even if ICMP echo/reply (smurf) packets are sent to the
broadcast address.

Routed vs. Bridged PDUs
The DSL router supports both the VNET model and the 1483 Routed model
(derived from RFC 1483) for the transportation of PDUs (Protocol Data Units)
from the DSL router to the router in the core network. When operating in
Standard mode, the DSL router supports both routed and bridged PDUs. When
operating in VNET mode, the DSL router supports bridged PDUs only.
NOTE:
Standard mode vs. VNET mode is configured on the DSL card at the
DSLAM/GranDSLAM chassis.
Both ends of the network (e.g., the DSL router and the DSL line card or the core

Diagnostics and Troubleshooting Overview
There are several features available to assist in evaluating the Hotwire DSL
Router. The following sections are covered in this chapter:
Device Restart
Alarms Inquiry
The DSL router can be restarted locally or remotely. From the Command Line
Interface, type Restartand press Enter.
The DSL router reinitializes itself, performing a power-on self-test and resetting
the local System Log (SYSLOG).
show alarms
This command allows the operator to display the list of current alarm conditions, if any.
Minimum access level: Operator
The possible output lines are:
Alarm: Management Address Conflict
Alarm: Failed Selftest
Alarm: System Error
No alarm condition is set
Alarm condition reverts to Normal when the offending problem has been corrected.

Diagnostics and Troubleshooting
System Log
The Hotwire DSL Router can log significant system events (SYSLOG). The
SYSLOG can be maintained locally on the DSL router and can also be sent to a
remote SYSLOG server, preferably in the management domain. To activate:
H
The DSL router must be configured to enable the output of SYSLOG
messages via the syslog enablecommand. (The Management Controller
Card (MCC) has SYSLOG always enabled.)
H
H
An IP address (loopback or remote) must be supplied.
The SYSLOG can also be captured by a remote SYSLOG server running the
UNIX daemon syslogd or an equivalent program. It is necessary to know the
IP address where the syslogd resides and the UDP port number the syslogd
is using.
The advantage of using a remote SYSLOG server is that ALL events will be
maintained upon restart of the DSL router. The local SYSLOG is cleared
upon restart.
Events are classified by severity level and the system administrator can specify
the minimum severity to be logged.
show syslog
Displays the current status of system as enabled or disabled. If enabled, the severity
level, management IP address, and UDP port will be displayed.
syslog { enabled | disabled }
level { emer | err | norm | info }
management ip-addr x.x.x.x
port nnn
syslog {enable | disable}
Allows the user to enable or disable SYSLOG output. The SYSLOG IP address must be
entered (next command) and saved to complete enabling SYSLOG.
Minimum access level: Administrator/Config
enable – Enables SYSLOG output.
disable – Disables SYSLOG output.
syslog ip ip-addr
Specifies the IP address for the host to send system log entries to.
Minimum access level: Administrator/Config
ip-addr – The IP address for SYSLOG (typically loopback address of 127.0.0.1).
syslog port [port-number]
Specifies the UDP port number on the server to which the system events will be sent.
Minimum access level: Administrator/Config
port-number – The UDP port number. Default = 514.

Diagnostics and Troubleshooting
syslog level level
Specifies the minimum severity level to be logged. Refer to Table 6-1, SYSLOG
Messages, for a list of messages by severity level.
Minimum access level: Administrator/Config
level – The minimum level to be logged. The default is NORM.
The choices for severity level (displayed as high severity to low severity) are as follows:
EMER – emergency, the system is unusable
ERR – error conditions reported
NORM – normal or administrative reporting
INFO – informational reporting
Example: To log EMER and ERR severity levels, enter syslog level ERR
show log [number]
Displays the contents of the local system error log. (The 100 most recent SYSLOG
entries are kept locally.) The user specifies how many entries they wish to view. Entries
are displayed in reverse order from most recent to oldest.
number – The number of local entries to be seen. Default = 10. Range = 1–100.
NOTE: The SYSLOG retained locally will be reset at the DSL router if the restart
command is issued. External logs are retained after a DSL router restart.
SYSLOG Events
The following are some of the SYSLOG events that will be reported for defined
severity levels.

Diagnostics and Troubleshooting
Ping
The Ping program is an IP-based application used to test reachability to a specific
IP address by sending an ICMP echo request and waiting for a reply. From the
Command Line Interface, Ping can test connectivity upstream or downstream.
ping dest-ip [mgt | -x source-ip] [-l bytes] [-w time] [-i {eth1 | dsl1}]
Pings the specified destination IP address. Once Ping starts, the input prompt will not
redisplay until either the Ping finishes or the Ping command is aborted with Ctrl-c.
Minimum access level: Administrator
dest-ip – The destination IP address of the device to ping.
mgt – Specifies that the IP address is in the management domain (through the MCC).
Do not use with –x source-ip selection.
source-ip – The source IP address to be used. The default source address is from the
service domain in which the test is being done. The IP address is validated to verify that
it is an interface IP address.
bytes – Bytes of data (l = length). Default = 64 bytes. Range = 0–15,000.
time – Number of seconds to wait before ending ping attempt. Default = 10 seconds.
Range = 0–60.
interface – The target interface for the command (eth1|dsl1). Do not use with –x
source-ip selection.
Example: ping 135.300.41.8 –l 144 –w 30 -i eth1
Ping Test Results

Diagnostics and Troubleshooting
TraceRoute
The TraceRoute program is an IP diagnostic tool that allows you to learn the path
a packet takes from the service domain local host to its remote host.
If you are unable to ping a device in a Hotwire network configuration, you may
want to run TraceRoute to identify the link (destinations up to 64 hops) between
the DSL router and the device that is not forwarding the Ping message.
traceroute dest-ip [-x source-ip] [-l bytes] [-w time] [-h hops]
[-i {eth1 | dsl1}]
Performs TraceRoute to the specified destination IP address. Once TraceRoute starts,
the input prompt will not redisplay until either TraceRoute finishes or the TraceRoute
command is aborted with Ctrl-c.
Minimum access level: Administrator
dest-ip – The destination IP address for TraceRoute.
source-ip – The source IP address used. The default source address is from the
service domain in which the test is being done. The IP address is validated to verify that
it is an interface IP address.
bytes – Bytes of data (l = length). Default = 64 bytes. Range = 0–15,000.
time – Time (in seconds) before the TraceRoute is abandoned. Default = 10 seconds.
Range = 0–60.
hops – Decimal number that specifies the maximum number of hops to be tested.
Default = 8. Range = 0–128.
interface – The target interface for the command (eth1 | dsl1). Do not use with the
–x source-ip selection.
Example: traceroute 135.300.41.8 –w 80 -i eth1
TraceRoute Test Results
TraceRoute results display in the following format:
Tracing route to [x.x.x.x] over a max of nn hops with nnn

Command Line Interface
Navigation
The Hotwire DSL router uses the following keys (as do most terminal emulation
programs):
H
Enter or Return – Accepts the input.
H
H
H
H
H
Ctrl-c – Aborts the entry or clears the input line.
Down Arrow – Repeats an entry within the last five entered.
Up Arrow – Displays the last entry.
Left Arrow – Moves the insertion point one space to the left.
Right Arrow – Moves the insertion point one space to the right.
Command Recall
The Hotwire DSL router keeps a history of the last several commands entered on
the command line interface. For example, if you press the Up Arrow key, the most
recently entered command will appear on the command line, where it can be
edited and reentered by pressing Enter. If you press the Up Arrow key again, the
next most recent command will appear, etc.
After pressing the Up Arrow key one or more times, pressing the Down Arrow key
moves down the list of recent commands, wrapping past the end of the list in
either direction.
Commands appearing in the command line can be edited. Use the Left and Right
Arrow keys to move the insertion point, enter the new characters or use the
Delete key to delete the character just to the left of the insertion point.

Command Line Interface
Interface and Service Domain IP Address
ifn address {eth1[:ifn] | dsl1[:ifn] } ip-address mask [primary]
ifn {dsl1[:ifn] | eth1[:ifn] } primary
ifn address dsl1 unnumbered
Specifies the IP address associated with either the Ethernet interface or the DSL
interface. Up to four (4) IP addresses may be assigned on each interface. An interface
address and mask cannot be changed while there is a static route (upstream or
downstream) that uses it. Interface IP address ranges must not overlap.
Minimum access level: Administrator/Config
eth1, eth1:1, eth1:2, eth1:3, eth1:4 – Ethernet interface. eth1 is the same as eth1:1.
dsl1, dsl1:1, dsl1:2, dsl1:3, dsl1:4 – DSL interface. dsl1 is the same as dsl1:1.
ip-address – The IP address associated with the specified interface.
mask – Mask for the associated subnet.
primary – The Primary designation of a numbered interface marks that interface as the
one whose IP address will be used as the Router ID. (The Router ID is important when
the DSL interface is unnumbered.) If no interface is defined as Primary, the last
numbered interface created will become the Primary IP Address.
unnumbered – Specifies that the DSL interface is to be unnumbered.
NOTES: – For each defined Ethernet interface, a corresponding upstream next hop
router IP address must be configured for routing of packets received on
that interface. See ip route create upstreamcommand on page
A-6 for more details.
– When the eth1 is assigned an IP address, this section also defines the
logical network (subnet) containing the locally attached hosts. An IP
route table entry will automatically be created to correspond to the
subnet defined by the mask.
– When the DSL interface is numbered, multiple logical Ethernet interfaces
can be assigned to the same DSL logical interface by configuring the
same upstream next hop router.
– The configured DSL logical interfaces must be either all numbered or a
single unnumbered interface.
– When NAT is being used, the DSL interface must be numbered. Only
one logical interface must be defined for each physical interface, i.e.,
one IP address to each interface.
– When NAT, DHCP Server, or DHCP Relay is enabled, there can be only
one service domain configured.

Command Line Interface
delete {eth1[:ifn] | dsl1[:ifn] }
Deletes any of the assignments that are configured for the interface. Only the specific
Ethernet or DSL interface number needs to be specified.
An interface address and mask cannot be deleted while there is a static route (upstream
or downstream) that uses it. First, delete the IP route with the ip route delete
command (see IP Routing Table).
Minimum access level: Administrator/Config
eth1, eth1:1, eth1:2, eth1:3, eth1:4 – Ethernet interface. eth1 is the same as eth1:1.
dsl1, dsl1:1, dsl1:2, dsl1:3, dsl1:4 – DSL interface. dsl1 is the same as dsl1:1.
Only dsl1 or dsl1:1 are acceptable inputs for an unnumbered interface.
Example: delete eth1:4
IP Routing Table
ip route create dest-ip dest-mask {next-hop-ip | remote}
ip route delete dest-ip dest-mask
Configures the downstream static routes. Downstream routes cannot be created unless
at least one Ethernet interface has been configured. To configure upstream routers, refer
to the next set of entries.
create – Create a downstream IP route table entry. To configure a downstream default
gateway, enter a destination IP address and a subnet mask of 0.0.0.0.
delete – Delete a downstream IP route table entry. This will delete an IP route placed in
the table by the DHCP server, the DHCP relay, or manually entered static entries.
NOTE: An interface route is created automatically when an address and mask are
assigned to an Ethernet interface with the ifn address command. The
Ethernet interface route can be deleted with the ip route purgeor the
ip route deletecommand. Once deleted, the interface route can be
entered manually using ip route createor a new ifn address
command.
dest-ip – IP address of the destination. The destination IP address must be within the
address range of a configured Ethernet interface or the next-hop-ip address must be
provided.
dest-mask – IP mask for the destination IP address.
next-hop-ip – IP address of the next hop downstream router used to reach the
destination. A next hop with an IP address of 0.0.0.0 specifies a directly reachable client.
A nonzero next-hop-ip address must be within the address range of an Ethernet
interface.
remote – Indicates that the device specified by the destination IP and destination mask
is logically within a local subnet route but is not on the physical Ethernet and resides
upstream from the DSL router. A remote route cannot be created unless at least one
DSL interface has previously been configured.
Example: Refer to Chapter 4, DSL Router Configuration Examples.

SNMP Overview
The Simple Network Management Protocol (SNMP) is an application-level
protocol used in network management to gather information from network
devices. Each DSL router runs an SNMP agent that collects data. The network
management station in the NAP domain can exercise all the management
functions remotely from the Network Operations Center (NOC).
There is no discovery of the DSL router, and it does not appear on the
Management Domain map. SNMP security is configured on the MCC card and all
SNMP requests to the DSL router are authenticated at the MCC. The MCC is the
destination for all traps originated by the DSL router.
See the Hotwire Management Communications Controller (MCC) Card, IP
Conservative, User’s Guide for more information on SNMP.
NOTE:
There are several SNMP Sets that result in resetting the DSL router. When
this happens, the NMS that sent the Set command may not receive a
response from the DSL router and will time out. This is not an error.
Traps Overview
Traps inform the NMS of an alert occurring in the system (e.g. threshold
exceeded). Traps are sent at the start and completion of a test or alarm condition.
The MCC is the destination for all traps originated by the DSL router. These traps
are then rebuilt with the trap destination information stored on the MCC and
forwarded to the appropriate trap managers.
Traps are configured via a Telnet session, terminal session, or via SNMP, and are
based on community names. Traps are included in the MIB II, Entity and Hotwire
Enterprise MIB definitions. MIBs can be accessed through the Paradyne Web site
The DSL system can send traps to three IP addressable destinations per
community (for a total of 12 destinations).

Traps & MIBs
MIBs Overview
The Hotwire DSL system supports standard as well as Paradyne Enterprise
MIBs. Various configuration, status, and statistical data within the SNMP agent is
accessible from the NMS. The content of an SNMP agent’s MIBs is defined by
various Internet Request for Comments (RFC) documents.
The following sections provide brief descriptions about supported MIBs.
Complete, up-to-date details about the content of all DSL MIBs are available on
MIBs.
