Edge Router Module Features
Topology Switching
1-7
Using topology switching you can:
■
Switch the ONline Edge Router module among any of three Ethernet
networks (channels) on the hub backplane
■
Switch the ONcore Edge Router module among any of eight Ethernet
networks (channels) on the hub backplane
You perform topology switching using:
■
Network management module commands
■
Simple Network Management Protocol (SNMP)
You do not have to swap cables or move the Edge Router module to move
the routing or bridging functions to a different network within an ONline or
ONcore hub. You can enter a command through one of the 3Com
management modules and the network change is made automatically.
Network Reliability
The Edge Router module lets you implement several levels of reliability in
your network as follows:
■
By routing the Edge Router module’s serial and auxiliary ports in parallel,
you can create up to three redundant links.
■
If the primary link fails, you can have up to two backup links in place to
ensure application availability.
These links can also implement load-balancing to enhance network
performance. An example of a reliable network configuration is shown in
Figure 1-3.

C HAPTER 3: CONFIGURING THE EDGE ROUTER M ODULE
Configuring the
Carrier in a
Managed ONline
Hub
This section describes how to use network management commands to
configure ONline carriers installed in an ONline System Concentrator. This
section contains the following topics:
■
Selecting a Network
■
Saving the Configuration
When you install the carrier in a hub with a management module installed,
the network defaults to isolated mode (Isolate_1). You must assign a
network as described below.
Selecting a Network
The engine connects to the backplane through a carrier module port on the
ONline carrier. You can assign the carrier module port to:
■
One of three Ethernet backplane networks
■
Isolated mode
For details on backplane networks, refer to the ONline System Concentrator
Installation and Operation Guide (Document Number 17-00417).
To assign the carrier module ports to a network using the network
management software, use the following command:
ONline> set port slot.port network
{ethernet_1 ... _3}
{isolated_1}
For example, the following command sets port 1 in the ONline carrier
installed in slot 3 to the Ethernet 2 backplane network:
ONline> set port 3.1 network ethernet_2
Port 03.01 network id set to ETHERNET_2
Saving the
Configuration
To save configuration changes, use the SAVE command. For example, the
following command saves all configuration changes:
ONline> save all
If you do not save module settings, you may lose configuration data.

Saving the Configuration
When you install the carrier in a hub with a management module installed,
the network defaults to isolated mode (Isolate_1). You must assign a
network as described in the sections that follow.
ONcore Carrier
Configuration
Sources
In a managed hub (a hub with a DMM installed), the ONcore carrier obtains
its configuration settings from one of the following sources:
■
DMM settings
■
Carrier NVRAM settings
■
Carrier DIP switch settings
■
Carrier default settings
DMM Settings
The DMM can provide configuration settings to the ONcore carrier if you are
performing a hot swap. For more information on hot swapping, refer to Hot
Swapping an ONcore Module on page 3-7.
3-6
C HAPTER 3: CONFIGURING THE EDGE ROUTER M ODULE
Carrier NVRAM Settings
The ONcore carrier can store configuration settings in its NVRAM
(non-volatile random access memory), which it can use when powering on
in either a managed or unmanaged hub. Two NVRAM DIP switches control
whether or not the carrier uses NVRAM settings. For information on setting
the NVRAM DIP switches, refer to Enabling or Disabling NVRAM
Configuration on page 2-10.
When the ONcore carrier ships from the factory, the NVRAM does not
contain any configuration settings.
The carrier stores configuration settings in NVRAM when either of the
following occurs:
■
You use a DMM configuration command or an SNMP manager to change a
carrier configuration setting. For example, if you use the SET PORT
NETWORK command to change a carrier port network assignment, the
carrier stores the new network assignment in its NVRAM.
The carrier stores the new setting as soon as you issue the command. The
SAVE command does not affect the contents of NVRAM.
■
The DMM sends configuration settings to the carrier during a hot swap. For
a definition of hot swap, refer to Hot Swapping an ONcore Module on
page 3-7.
Carrier DIP Switch Settings
The carrier contains a DIP switch that you can use to configure network
assignments. For more information on DIP switch settings, refer to
Configuring the ONcore Carrier DIP Switches on page 2-9.
Carrier Default Settings
In some cases, the carrier uses default configuration settings contained in its
software. The default network assignment for the ONcore carrier is Isolate_1.
Configuring the Carrier in a Managed ONcore Hub
Hot Swapping an
ONcore Module
3-7
You can remove a module from the ONcore hub and install an identical
module in the same slot without powering off the hub. This is called a hot
swap. Whether or not you hot swap the Edge Router module affects which
configuration source the carrier uses.
When you perform a hot swap, the DMM transfers to the new carrier the
configuration used by the old carrier. The new carrier saves the settings in
its NVRAM.
The DMM transfers the configuration to the new carrier only if it has a saved
configuration for the old carrier installed in that slot. The DMM saves the
configuration when you perform one of the following:
■
Issue the SAVE command.
■
Use SNMP to make the configuration changes to the carrier. The DMM
automatically saves the changes.
■
Reset or power-cycle the DMM. The DMM automatically acquires and saves
the NVRAM configurations of all installed modules.
Swapping in a new carrier that contains a different engine from the old
carrier is still a hot swap. Only the carrier models must be the same.

† If the carrier does not have configuration settings stored in NVRAM, it uses default settings.
If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use
default settings. For example, if you install the carrier with ports assigned to Ethernet_8 into an
ONcore hub model that does not support Ethernet_8. If the configuration problem is port
level, the DMM forces only the affected ports to use default settings.
‡ The DMM must be fully initialized when you install the carrier module.
Selecting a Network
The Edge Router engine connects to an Ethernet network through a
backplane port on the ONcore carrier. A base engine installed in ONcore
carrier engine bay 1 uses carrier backplane port 1. A base engine installed in
ONcore carrier engine bay 2 uses carrier backplane port 5.
You can assign a carrier backplane port to:
■
One of eight Ethernet backplane networks
■
One of four Isolated backplane networks
For details on backplane networks, refer to the ONcore Switching Hub
Installation and Operation Guide (Document Number 17-00362-5).
Configuring the Edge Router Engine
3-9
To assign a carrier backplane port to a network using network management
software, use the following command:
set port
slot.port network {ethernet_1 ... ethernet_8}
{isolated_1 ... isolated_4}
For example, the following command sets backplane port 1 (engine 1) in
the carrier installed in slot 3 to Ethernet_2:
ONcore> set port 3.1 network ethernet_2
Port 03.01 network id set to ETHERNET_2
Saving the
Configuration
To save configuration changes, use the SAVE command. For example, the
following command saves all configuration changes:
ONcore> save all
If you do not save module settings, you may lose configuration data.

■
Troubleshooting 3Com Carrier Problems
Troubleshooting
Router-Specific
Problems
When you first install the Edge Router module in an ONline or ONcore hub
the Cisco engine runs a full set of hardware diagnostic tests. If the engine
fails diagnostics, the Router (RTR) LED does not illuminate or will flash. This
indicates a problem with the router hardware or software. Refer to the
appropriate Cisco Systems troubleshooting documentation for corrective
action.
Troubleshooting
Mailbox Interface
Problems
ONline and ONcore Edge Routers use a hardware mailbox interface that
allows the Cisco engine to communicate with the 3Com carrier board
during powerup. If the 3Com mailbox does not establish communication
with the engine, the following message is reported to the engine console
port:
%MAILBOX-3-INITFAIL:Mailbox initialization failure.
Not getting interrupts. Mailbox offline.
If you see this message, contact your 3Com representative for assistance.
Troubleshooting
3Com Carrier
Problems
Before mailbox communication is initialized and established between the
Cisco engine and the 3Com carrier, the Module Status (S) LED on the front
panel of the Edge Router module blinks slowly. If communication is
established successfully, the Status LED illuminates and stays on solid. If the
Status LED does not light, the 3Com carrier board has malfunctioned.
Contact your 3Com representative for assistance. Refer to Appendix B for
instructions on contacting Technical Support for you product.

If the Edge Router module does not appear to be routing traffic properly on
the network, it may indicate that there is no connection to the network.
Try performing one or more of the following troubleshooting actions:
■
For ONline and ONcore Edge Router modules only, use the 3Com
management interface (for example, ONline management module) to verify
that the Edge Router module backplane port is set to the appropriate
backplane network (channel).
■
Using the Cisco terminal interface, verify that the following parameters are
set correctly:
■
IP address
■
Subnet mask
■
Default gateway
■
Use the ping utility to confirm that there is network connectivity.
■
Use the cisco>show interfaces ethernet 0 command to verify that
the interface is up and running. This command reports Ethernet statistics
that aid you in troubleshooting the network.
If the interface is down, you may need to use the Cisco configuration editor
to issue the no shutdown command. The no shutdown command
restarts a disabled interface.
■
Verify that your router configuration is valid. Refer to the Cisco Systems
Troubleshooting Internetworking Systems guide for more information.
5-4
C HAPTER 5: TROUBLESHOOTING
Troubleshooting
WAN
Connectivity
Problems
If you suspect that the Edge Router module has lost WAN connectivity,
perform one or more of the following troubleshooting actions:
■
Verify that you have the correct cable for your configuration. Refer to
Appendix A, Specifications, for a list of approved cables, cable
specifications, and pinouts.
■
If you are using a:
■
■
DCE cable — Verify that a clock rate is defined in the router WAN
interface configuration.
DTE cable — Verify that no clock rate is defined in the router WAN
interface configuration.
■
Verify that the cable’s 60-pin WAN connector is not plugged in backwards.
■
Ensure that the router configuration does not have a SHUTDOWN command
associated with the interface.
■
Verify that your router configuration is valid. Refer to the Cisco Systems
Troubleshooting Internetworking Systems guide for more information.

Accessing the
3Com ISD MIB
The 3Com Management Information Base (MIB) for the Integrated Systems
Division (ISD) describes commands that enable you to manage 3Com
SNMP-based products. The MIB is available over the Internet on an
anonymous FTP server. Updates to these MIBs are released as new 3Com
products are introduced.
To access Internet versions:
1 FTP to ftp.chipcom.com (151.104.9.65).
2 Enter the login name anonymous.
3 Enter your full Internet e-mail address as the password
(for example, [email protected]).
4 Change to the mib or schema directory using the cd /pub/mibs or
cd /pub/mibs/schemas command.
5 To view the 3Com MIB, OID, or schema entries, enter the dir command.
■
To pause the display, press [Ctrl+S].
■
To continue the display, press [Ctrl+Q].
6 Copy the MIB, OID, or schema files to your current directory using the
appropriate command (for example, get chipcom.mib).
7 To exit the FTP session, invoke the quit command.
