Router Module Features
This section describes the following major features of the router module:
■ FDDI Support
■ WAN Support
■ Protocol Translation
■ Scalable Protocol Support
■ WAN Optimization
■ ATM Migration
■ Management Support
■ Distributed, Scalable Reliability
■ Hot Swap Capability
FDDI Support The router module provides support for three FDDI configurations on the following two FDDI interfaces:
Multi-Mode Fiber – Can support distances of up to 2 km for both Class A Dual Attachment Stations (DAS) and Class B Single Attachment Stations (SAS).
Single Mode Fiber – Can support distances of up to 10 km for Class A Dual Attachment Stations (DAS).
The FDDI interfaces also include a connector for attachment to an external optical bypass unit. If the router module stops operating, the optical bypass unit ensures that the FDDI signal bypasses that router. The FDDI ring and other stations remain operational.
WAN Support The router module configured with a Quad Serial NIM provides four synchronous serial ports to support backbone or redundant network connections over the wide area network (WAN). The serial ports support the following connection protocols:
■ V.35
■ EIA-232
■ EIA-449
■ RS-422
■ X.21
Router Module Features 1-7
Each serial port is capable of providing T1/E1 rate connectivity. Each port operates in full duplex mode at speeds from 1,200 bits per second (bps) to 2,048 Megabits per second (Mbps).
You can configure the synchronous serial ports to support IBM® Synchronous Data Link Control (SDLC) traffic using synchronous pass through or Data Link Switching (DLSw).
Protocol Translation The router module protocol translation function allows you to extend the life of your existing network devices. The router module allows networks operating in dissimilar protocol environments to communicate while it manages up to 180 simultaneous sessions.
The router module supports the following bidirectional translations:
■ X.25 to TCP
■ X.25 to Local Area Transport (LAT)
■ X.25 to XRemote devices
■ LAT to TCP
■ LAT to TN3270 devices
Scalable ProtocolSupport
Each router module type allows you to select a specific level of protocol support to best match the needs of your application. Four Cisco IOS router software feature sets offer an increasing level of protocol support:
IP/IPX – Base feature set for use in applications requiring only IP/IPX protocols.
Desktop – Provides additional LAN support for use in applications with limited LAN protocol requirements.
Desktop plus IBM – Adds IBM support.
Enterprise – Adds top-level protocol support, including SNA (Synchronous Network Architecture) integration.

Router Module Features 1-9
WAN Optimization The router module provides the following features to help limit network operating costs by optimizing WAN network connections:
Dial-On-Demand Routing – A more economical alternative to a second leased line as backup, a dial-on-demand backup dials up a second line automatically if the primary WAN link fails.
Data Compression – The router module provides four types of data compression for different network environments:
■ Link compression
■ X.25 packet payload compression
■ TCP/IP header compression
■ DEC™ LAT compression
ATM Migration The router module can be upgraded to support your migration to an ATM backbone (see Figure 1-3).
Add an ATM network backbone by replacing your original router module NIM (network interface module) with one of two ATM NIM types:
■ OC-3, MM (Optical Carrier Type 3, Multi-Mode)
■ OC-3, SM (Optical Carrier Type 3, Single Mode)
Each ATM NIM type provides 155 Mbps backbone bandwidth.
ManagementSupport
The router module is shipped with a comprehensive Management Information Base (MIB) for using Simple Network Management Protocol (SNMP), the industry standard for network management.
You can monitor and control the router module from any SNMP-based management station, including the 3Com Transcend Enterprise Manager.
In addition, the router module is fully compatible with CiscoWorks® network management software from Cisco Systems.
TELNET capability provides for direct access in-band to the agent, and a console port on the module provides for out-of-band management capability.
1-10 INTRODUCTION
Distributed, ScalableReliability
The router module operates in the CoreBuilder 5000 Integrated System Hub which is structured to eliminate any single point of failure.
The CoreBuilder 5000 hub provides redundancy for power supplies, switched ports, controller modules, and the hub management module. Automatic switching to the redundant components ensures continuation of the specific function.
3Com fault-tolerant features are fully-scalable, allowing you to implement and alter the degree of fault-tolerance you need as your network grows.
Hot Swap Capability The router module features “hot swap” capability. You can swap the router module in or out of (install or remove from) a powered-on CoreBuilder 5000 hub.

Installing the Router Module
This section describes how to install the router module in the CoreBuilder 5000 Integrated System Hub.
You do not need to power down the hub to install or remove the router module. You can insert the module while the hub is operating (hot swap capability).
To install the router module:
1 Properly ground yourself prior to handling the module.
Put on a static wrist guard or touch a grounded static mat before you handle the module.
2 Locate 3 adjacent open slots in the hub, or remove panels on the hub to expose 3 slots for the router module.
3 Insert the router module into the board guides at the top and bottom of the slot and slide it into the hub by pressing firmly at the top and bottom of the faceplate. Make sure that the module ejectors are open fully when you insert the module and that the connectors are well-seated into the backplane of the hub. Figure 2-4 shows a router module being installed in a CoreBuilder 5000 Integrated System Hub.
2-8 INSTALLING THE MODULE
Figure 2-4 CoreBuilder 5000 Network Router Module in a CoreBuilder 5000 Integrated System Hub
To minimize electromagnetic interference, ensure that the slots adjacent to the router module are occupied or have blank panels installed.

■ Connecting the Single Mode, Dual Attachment Station NIM
Connecting the Multi-Mode, Dual Attachment Station NIM
The Multi-Mode, Dual Attachment Station NIM (MM, DAS) connectors are Fiber Distributed Data Interface (FDDI) standard physical sublayer (PHY) connectors. The media interface connector (MIC) connects to FDDI-standard 62.5/125 micron multi-mode fiber optic cable.
Figure 2-5 shows the MIC connector typically used for network and chassis connections in multi-mode FDDI applications.
Figure 2-5 Multi-Mode FDDI Network Interface Connector, MIC Type
A dual attachment station requires two connections, one to the primary ring and one to the secondary ring. On the FDDI MM, DAS NIM, the PHY-A port is the left port and PHY-B is the right port.

ATM Distance Limitations
The SONET (Synchronous Optical Network) specification for fiber-optic transmission defines two types of fiber:
■ single mode
■ multimode
Single-mode fiber is capable of higher bandwidth and greater cable run distances than multimode fiber.
The typical maximum distances for single-mode and multimode transmissions, as defined by the SONET, are provided in Table 2-4. If you connect two optical devices at a distance greater than those specified in Table 2-4, significant signal loss could occur, making transmission unreliable.

CONFIGURING THE MODULEThis chapter contains the following sections:
■ Configuration Overview
■ Attaching a Management Terminal
■ Configuring Cisco NIM Connections
■ Configuring Cisco Parameters
■ Configuring 3Com Parameters
CAUTION: Throughout this chapter, Cisco nomenclature refers to the four Ethernet backplane connections as interfaces 0, 1, 2, and 3. 3Com refers to the same four router connections as ports 1, 2, 3, and 4. For example, when configuring the router module, Cisco interface 0 is equivalent to 3Com port 1.
Configuration Overview
The following list is an overview of the procedures that are required to configure the router module. For more detail, refer to sections that follow.
CAUTION: Failure to follow the configuration sequence specified in this section could result in error messages at the router management terminal during the configuration procedure. For best results, use the procedure as outlined in the sections that follow.
To configure the router module:
1 Attach a Management Terminal – Attach a management terminal to the console port of the router module.
2 Configure Cisco NIM Connections – From the management terminal, use Cisco router configuration commands to configure the NIM (Network Interface Module) connections.
3-2 CONFIGURING THE MODULE
3 Configure Cisco Parameters – Use the management terminal to configure the four Cisco router interfaces.
4 Configure 3Com Parameters – Use the management terminal that is connected to the 3Com CoreBuilder™ 5000 Distributed (DMM) to configure the four 3Com router ports.
Each of these steps is detailed in the sections that follow.
If you are using the router module in an unmanaged hub (one in which a DMM module is not installed), upon power on, the router module uses the last module configuration saved in NVRAM. To enable NVRAM configuration, set DIP switch SW2-7 to On (see Figure 2-2).
When you power on the router module with NVRAM configuration disabled, the four Ethernet ports are set to isolated mode, or to what the DIP switch settings specify. Refer to Setting DIP Switches on page 2-4.
Attaching a Management Terminal
This section provides information on attaching a terminal to the console or auxiliary ports of the router module for use as a Cisco management terminal.
You must use the console port for initial router configuration. After you configure the router, you can use the auxiliary port for an asynchronous serial connection.
Connecting to theConsole Port
All router modules include an asynchronous router console port (female DB-25 connector) wired as a data communications equipment (DCE) device. The port requires a straight-through cable for connection to a local terminal. The port uses the following default parameters:
■ 9600 baud
■ 8 data bits
■ No parity generated or checked
■ 2 stop bits
Configuring Cisco NIM Connections 3-3
Connecting to theAuxiliary Port
All router modules include a male DB-25 connector auxiliary port (labeled AUX PORT DTE). The auxiliary port is a shared-memory data terminal equipment (DTE) port to which you can attach an EIA/TIA-232 connector from a channel service unit or data service unit (CSU or DSU), a modem, or protocol analyzer for network access.
Console and auxiliary port cabling requirements are provided in Appendix B, Cabling Specifications.
Configuring Cisco NIM Connections
From the Cisco management terminal, use Cisco IOS routing configuration commands to configure the FDDI or Quad Serial NIM connections.
If you are configuring a base router module without a NIM installed, proceed to the next section Configuring Cisco Parameters.
You may receive status messages referring to NIM 1, NIM 2, and NIM 3. Cisco IOS makes the following NIM designations:
■ Optional NIM as NIM 1
■ Ethernet backplane interfaces 0 and 1 (3Com ports 1 and 2) as NIM 2
■ Ethernet backplane interfaces 2 and 3 (3Com ports 3 and 4) as NIM 3
For detailed information on Cisco IOS routing configuration commands, refer to the Cisco hardcopy documentation set(Part Number 17-00138-MS) or to the Cisco documentation set on the Cisco UniverCD™ CD-ROM (Part Number 17-00138-CD).
Configuring Cisco Parameters
This section outlines procedures for configuring Cisco parameters for the four Ethernet interface connections on the router module using Cisco IOS software management commands. The procedures include:
■ Setting the Initial Router Module Configuration
■ Setting General Interface Parameters
■ Re-Starting the Interface Ports
3-4 CONFIGURING THE MODULE
Setting the InitialRouter Module
Configuration
When you first install the router module, you must define its basic configuration. Use the Cisco Setup utility to define the initial router module configuration.
To define the initial router module configuration:
1 Use DMM at the CoreBuilder 5000 management station to ensure that each router interface port is in Isolated mode. In the following example involving a module in slot 7, port 1 is set to Isolated mode:
CB5000> set port 7.1 network isolatedPort 07.01 network id set to ISOLATED.

Troubleshooting Startup Problems
This section describes how to troubleshoot startup problems on the CoreBuilder 5000 Network Router Module.
When you first install the router module in the hub, the Cisco Systems router software runs a set of hardware diagnostic tests. If the router module fails diagnostics, the MOD STATUS LED blinks and the SYS RUN LED does not light. This indicates a problem with the router module hardware or software. Refer to Table 4-1 on page 4-3 for more information on router module LED indications. Refer to the appropriate Cisco Systems troubleshooting documentation for corrective action.
5-2 TROUBLESHOOTING
Troubleshooting Network Connection Problems
If the CoreBuilder 5000 Network Router Module does not appear to be routing traffic properly on the network, it may indicate that there is no connection to the network. Perform the following troubleshooting actions:
■ From the 3Com management interface (for example, CoreBuilder 5000 Distributed Management Module), verify that the router module backplane port is set to the appropriate backplane network (channel).
■ Use the DMM SHOW PORT command and check the Status field for the port. Refer to Using the SHOW PORT VERBOSE Command on page 4-12.
■ Use the ping utility to confirm there is network connectivity.
■ Verify that your router configuration is valid. Refer to the Cisco Systems Troubleshooting Internetworking Systems guide for more information.
Troubleshooting WAN Connection Problems
If you suspect that the CoreBuilder 5000 Network Router Module has lost WAN connectivity, perform the following troubleshooting actions:
■ Verify that you have the correct cable for your configuration. Refer to Appendix B, Cabling Specifications, for lists 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 your router configuration is valid. Refer to the Cisco Systems Troubleshooting Internetworking Systems guide for more information.
Correcting Operating Malfunctions 5-3
Correcting Operating Malfunctions
Table 5-1 lists the symptoms, possible causes, and corrective actions of operating malfunctions for the CoreBuilder 5000 Network Router Module.
.
Table 5-1 Troubleshooting Malfunctions
Symptom Possible Cause Corrective Action
Module does not power up Module is not fitted correctly against backplane.
To ensure that the module is fitted correctly, remove the module from the slots and replace it in the slots.
Place the module in different slots in the hub.
Power mode is not enabled for slot.
Ensure that power mode is enabled for the slot.
The hub is not receiving electrical power.
Check that the hub is receiving power.
Test for power at the wall outlet by plugging in another device.
If the wall outlet is not receiving power, select another outlet on a different circuit.
Attached terminal does not operate
The terminal is malfunctioning.
Follow the troubleshooting procedures recommended by the terminal manufacturer.
Cables are unattached. Make sure that the cable connections at both ends are secure.
Cables are not the correct type.
Make sure that the cable attached to the terminal conforms to the specification. Refer to Appendix B for cabling specifications.
The console is configured incorrectly.
Check the console port configuration.Note: You can use TELNET to verify port configurations.
Refer to the Cisco Systems Router Products Configuration and Reference documents for more information. Verify that the port is configured as:
■ 8-bit data
■ No parity
■ 2 stop bits
■ 9600 baud rate
■ Flow control parameters set to Xon and Xoff
5-4 TROUBLESHOOTING
Recovering a Lost Password
To recover a lost password:
1 Attach an ASCII terminal to the router module console port.
2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 2 stop bits.
3 Enter the SHOW VERSION command to display the existing configuration register value. Note this value for later use in step 13.
4 If the Break function is disabled on the router (refer to Table C-1), power cycle the router (turn off the router, wait 5 seconds, and then turn it on again). If the Break function is enabled, go to step 5.
5 Within 60 seconds of turning on the router, press the Break key. Pressing this key causes the terminal to display the bootstrap program prompt (>).
6 To reset the virtual configuration register (VCR) to boot from the boot ROMs and ignore NVRAM, enter the O/R (Reset VCR Value) command at the bootstrap prompt:
> o/r 0x2141
To recover a lost password, you must be able to see it when you display configuration information. To see the password, be sure to set the configuration register so that the router module engine ignores the contents of the NVRAM.
The terminal fails to respond to commands entered at the keyboard
The terminal is not receiving commands.
Power off the terminal, wait 30 seconds, and then power on again.
The keyboard cable is attached incorrectly.
If the terminal still does not respond to commands, power off the terminal and disconnect the keyboard cable. Then re-attach the keyboard cable and power on the terminal.
Cables are not the correct type.
Make sure that the cable attached to the terminal conforms to the specification. Refer to Appendix B for cabling specifications.
The console port is malfunctioning.
Check the state of the LEDs on the front of the module. If the LEDs indicate a problem, contact your supplier for assistance.

Recovering a Lost Password 5-5
7 Initialize the router by entering the I (Initialize) command as follows:
> i
The router power cycles and the configuration register is set to 0x2141 (ignore Break key, ignore NVRAM, boot from ROM). The router boots the boot ROM system image and prompts you with the following system configuration dialog prompt:
--- System Configuration Dialog ---
8 Enter No in response to the system configuration dialog prompts until the following system message appears:
Press RETURN to get started!
9 Press Return. The boot ROM prompt appears as follows:
Router(boot)>
10 Enter the ENABLE command to enter the EXEC mode in the boot ROM image. The prompt changes to the following:
Router(boot)#
11 Enter the SHOW CONFIGURATION EXEC command to display the password in the configuration file and to display any boot system commands.
12 To exit configuration mode, press Ctrl-Z.
13 Restore the virtual configuration register to the value noted in step 3. Use the CONFIGURE TERMINAL command to restore the value:
router# configure terminalEnter system configuration commands, one per line.

VIRTUAL CONFIGURATION REGISTERThe CoreBuilder™ 5000 Network Router Module has a 16-bit virtual configuration register, which is written into the nonvolatile random-access memory (NVRAM).
This appendix describes the virtual configuration register (VCR), the factory-default settings for the register, and the procedures for changing those settings.
This appendix contains the following sections:
■ VCR Tasks
■ VCR Bit Definitions
■ Changing VCR Settings
■ Enabling Booting From Flash Memory
VCR Tasks Use the virtual configuration register to perform the following tasks:
■ Set and display the configuration register value
■ Force the system into bootstrap mode
■ Select a boot source and default boot filename
■ Enable or disable the Break function
■ Control broadcast addresses
■ Set the console terminal baud rate
■ Load operating software from ROM
■ Enable booting from a TFTP (Trivial File Server Protocol) server
C-2 VIRTUAL CONFIGURATION REGISTER
VCR Bit Definitions Table C-1 defines each of the virtual configuration register memory bits.
To avoid confusion and possibly disabling the router, remember that valid register settings may be combinations of settings and not just the individual settings listed in Table C-1. For example, the factory-default value of 0x2102 is a combination of settings.
* The factory-default value for the configuration register is 0x2102. This value is acombination of settings (bit 13 = 0x2000, bit 8 = 0x0100, and bits 00 through 03 =0x0002).
Boot Field The lowest four bits of the virtual configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field specifies a binary number. Table C-2 defines the boot field binary values.
Table C-1 Virtual Configuration Register Bit Values
Bit No.* Hex Value Meaning
00 to 03 0x0000 to 0x000F
Boot field
06 0x0040 Causes system software to ignore NVRAM contents
07 0x0080 OEM bit enabled
08 0x0100 Break function disabled
09 — Unused
10 0x0400 IP broadcast with all zeros
11 to 12 0x0800 to 0x1000
Engine management terminal baud rate
13 0x2000 Boot default ROM software if network boot fails
14 0x4000 IP broadcasts do not have net numbers
15 0x8000 Enable diagnostic messages and ignore NVRAM contents
Table C-2 Boot Field Values (Configuration Register Bits 00 to 03)
Bit Boot Field Meaning
0 0x1 Stays at the system bootstrap prompt.
1 0x2 Boots system image in system ROM.
2 to 3 0x4 to 0xF Specifies a default netboot filename and enables boot system commands that override the default netboot filename.
VCR Bit Definitions C-3
Setting Boot Field Values
To set the boot field values:
■ If you set a boot field value to 0, you must boot the operating system manually. To boot the operating system manually, enter the B command at the bootstrap prompt:
> b [tftp] flash IJ09140Z
For more information on the B command, refer to the Cisco Systems Router Products Configuration Guide.
■ If you set the boot field value to a value in the range of 0x2 through 0xF, and a valid system boot command is stored in the configuration file, then the router module boots the system software as directed by that value.
■ If you set the boot field to any other bit pattern, the router module uses the resulting number to form a default boot filename for netbooting (refer to Default Boot Filenames on page C-3).
In the following example, the virtual configuration register is set to boot the router module from Flash memory and to ignore the Break function at the next reboot of the router module:
router# configure terminalEnter configuration commands, one per line.Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Zconfig-register 0x102boot system flash IJ09140Z^Zrouter#
Default Boot Filenames
The network server creates a default boot filename as part of the automatic configuration process and stores the binary value in the virtual configuration register.
To form the boot filename, the server starts with cisco and links the octal equivalent of the boot field number, a hyphen, and the processor-type name. Table C-3 lists the default boot filenames or actions for the processor.
C-4 VIRTUAL CONFIGURATION REGISTER
A boot system configuration command in the router module configuration in NVRAM overrides the default netboot filename.
Break Function Bit 8 controls the way the server interprets the engine management terminal Break key. The server interprets the Break key in the following ways:
■ Setting bit 8 (the factory default) causes the processor to ignore the console Break key.
■ Clearing bit 8 causes the processor to interpret the Break key as a command to force the system into the bootstrap monitor, which halts normal operation. A Break command can be sent during the first 60 seconds of a system reboot, regardless of the configuration settings.

VCR Bit Definitions C-5
Internet ProtocolBroadcast Address
Bit 10 controls the host portion of the Internet Protocol (IP) broadcast address as follows:
■ Setting bit 10 causes the processor to use all zeros.
■ Clearing bit 10 (the factory default) causes the processor to use all ones.
Bit 10 interacts with bit 14, which controls the network and subnet portions of the broadcast address. Table C-4 lists the combined effect of bits 10 and 14.
Engine ManagementTerminal Baud Rate
Bits 11 and 12 determine the baud rate of the engine management terminal.
Table C-5 lists the bit settings for the four available baud rates. The factory-set default baud rate is 9600.
Bootload FailureResponse
Bit 13 determines the server response to a bootload failure as follows:
■ Setting bit 13 causes the server to load operating software from ROM after five unsuccessful attempts to load a boot file from the network.
■ Clearing bit 13 causes the server to continue attempting to load a boot file from the network indefinitely. The default setting for bit 13 is cleared.

C-6 VIRTUAL CONFIGURATION REGISTER
NVRAM Disable Bit 15 determines whether or not the server uses the contents of NVRAM as follows:
■ Setting bit 15 causes the server to ignore the configuration file in NVRAM and to enable diagnostic messages.
■ Clearing bit 15 causes the server to use the contents of NVRAM.
Changing VCR Settings
To change the values in the configuration register while running the system software:
1 Enter the ENABLE command and your password to enter the privileged level.
router> enablePassword:router#
2 At the privileged-level system prompt (router#), enter the CONFIGURE TERMINAL command. The system displays information about the configuration commands.
router# configure terminalEnter configuration commands, one per line.Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
3 To set the contents of the configuration register, enter the CONFIG-REGISTER command, where yyyy is a hexadecimal number preceded by 0x (refer to the Note on page C-2).
config-register 0xyyyy
4 Exit configuration mode by pressing Ctrl-Z. The new value settings are saved to memory. However, the new settings do not take effect until the system software reloads when the router module engine reboots.
5 To display the configuration register value currently in effect and the value that will be used at the next reload, enter the exec mode SHOW VERSION command. The value appears on the last line of the screen display as in the following example:
Configuration register is 0x142 (will be 0x102 at next reload)
6 Reboot the router module engine. The new value takes effect.
Enabling Booting From Flash Memory C-7
Configuration register changes take effect only when the server restarts. To restart the server, power off and then power on the router module or issue a reload command from the engine management terminal.
Enabling Booting From Flash Memory
To enable booting from Flash memory, set configuration register bits 3, 2, 1, and 0 to a value between 2 and 15.
To enter configuration mode, while in the system software image specify a Flash filename from which to boot. For example:
router# configure terminalEnter configuration commands, one per line.Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Zboot system flash IJ09140Z
To disable the Break key and enable the BOOT SYSTEM FLASH command, enter the CONFIG-REGISTER command with the value shown in the following example:
router# configure terminalEnter configuration commands, one per line.Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Zconfig-reg 0x2102^Zrouter#

Returning Products for Repair
Before you send a product directly to 3Com for repair, you must first obtain a Return Materials Authorization (RMA) number. Products sent to 3Com without RMA numbers are returned to the sender unopened, at the sender’s expense.
To obtain an RMA number, call or fax:
Accessing the 3Com MIB
The 3Com Management Information Base (MIB) 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.3com.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 /pub/mibs directory using the command cd/pub/mibs .
5 Read the readisd.txt file to determine the MIB or MIBs you need to manage your 3Com products.
6 To view the 3Com MIB, OID, or schema entries, enter the ls command.
■ To pause the display, press Ctrl+S.
■ To continue the display, press Ctrl+Q.
7 Copy the MIB, OID, or schema files to your current directory using the appropriate command (for example, get isd.mib ).
8 Exit the FTP session using the quit command.
