Router Module Overview 1-3

The base router module consists of a CoreBuilder 5000 14-inch base board with an attached CPU board. Both the base board and the CPU board plug directly into the CoreBuilder 5000 backplane.

The base router module provides four Token Ring backplane connections (complex port connections), any one of which you can connect to any one of 10 CoreBuilder 5000 backplane networks. The Token Ring ports are equivalent to Cisco Systems IOS interface connections.

You can connect only one Token Ring backplane connection to any one CoreBuilder 5000 backplane network.

You can mount any one of multiple standard Cisco Systems Network Interface Module (NIM) types on the base board to provide additional routing connections (Cisco Systems NPM connections) for various protocol types (see Figure 1-1

). Each NIM type requires a unique 3Com

faceplate.

Router Module Features

FDDI Support The router module provides support for three FDDI configurations on

This section describes the following 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

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 managing 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 Protocol

Support

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 – The base feature set is used 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.

Feature

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, with one of two ATM NIM types:

Management

Support

■ 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.

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 CHAPTER 1: INTRODUCTION

Distributed, Scalable

Reliability

The router module operates in the CoreBuilder 5000 Integrated System 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 off 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.

2-6 CHAPTER 2: INSTALLING THE 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 module being installed in a CoreBuilder 5000 Integrated System Hub.

CONFIGURING THE MODULE

This chapter contains the following topics:

■ Configuration Overview

■ Attaching a Management Terminal

■ Configuring the Cisco NIM Connections

■ Configuring Cisco Parameters

■ Configuring 3Com Parameters

CAUTION: Throughout this chapter, Cisco nomenclature refers to the four Token Ring 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 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 the Cisco NIM Connections – From the management

terminal, use Cisco router configuration commands to configure the NIM (Network Interface Module) connections.

3-2 CHAPTER 3: CONFIGURING THE MODULE

3 Configure the Cisco Parameters – Use the management terminal to

configure the four Cisco router interfaces, including interface speed.

Attaching a Management Terminal

4 Configure the 3Com Parameters – Use the management terminal

that is connected to the 3Com

CoreBuilder 5000 Distributed Management Module (DMM) to configure the four 3Com router ports, including CoreBuilder

™

5000 backplane network speed.

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 disable NVRAM configuration, set DIP switch 5 to Off (see Figure 2-2

When you power on the router module with NVRAM configuration disabled, the four Token Ring ports are set to isolated mode.

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 the

Console 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 the Cisco NIM Connections 3-3

Connecting to the

Auxiliary Port

Configuring the Cisco NIM Connections

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/data service unit (CSU/DSU), a modem, or protocol analyzer for network access.

Console and auxiliary port cabling requirements are provided in Appendix B, Cabling Specifications

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 (Model Number 6701CS-NN), 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

■ Token Ring backplane interfaces 0 and 1 (3Com ports 1 and 2) as

NIM 2

Configuring Cisco Parameters

■ Token Ring 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).

This section outlines procedures for configuring Cisco parameters for the four Token Ring interface connections on the router module using Cisco IOS software management commands. The procedures include:

■ Setting General Interface Parameters

■ Setting Token Ring Speed

3-4 CHAPTER 3: CONFIGURING THE MODULE

Setting General

Interface Parameters

Setting Token Ring

Speed

Set any required general Cisco parameters for the four router interfaces. Cisco Systems IOS software provides management commands for configuring routing interface connections. 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).

Set the Token Ring speed of each router interface connection to match the speed of the CoreBuilder 5000 backplane network to which it will be connected.

To set the Token Ring speed of a router interface:

1 Use DMM at the CoreBuilder 5000 management station to ensure that

the router interface port is in isolated mode:

CB50 00> set po rt 7.1 network iso lated Port 07 .01 networ k id set to I SOLATED.

2 At the router management terminal, set the configuration mode to

enable:

Rout er> e nable

3 Enter the required password:

Passwo rd: ****

4 Set the router management terminal to configuration mode:

Rout er# con fig termin al Enter c onfigurat ion command s, one per line. End with CNTL/Z. Router (config)#

5 Specify the number of the Token Ring interface:

Router (co nfig )# in terface tokenrin g 0 Router (config-i f)#

6 Shut down the router interface:

Router (co nfig -i f)# shutdown Router (config -if)#

7 Specify the ring speed of the router interface (in this example, 4 MBPS):

Router (co nfig -i f) # ring-speed 4 Router (config -if)#

Configuring 3Com Parameters 3-5

8 Remove the router interface from shutdown state:

Router (conf ig-i f)# no shutdown Router (config -if)#

9 Exit from configuration mode:

Rout er(conf ig-i f)# ^Z Rout er#

10 Save the interface configuration changes:

Rout er# w rite mem Building configuration... [OK] Router#

At this point, the system may display a sequence of RESET messages on the router management terminal. This a normal, temporary condition that ends when the interface synchronizes to the new speed.

Configuring 3Com Parameters

This section outlines procedures for using DMM commands to configure basic parameters for the 3Com router module.

Refer to the 3Com CoreBuilder 5000 Integrated System Hub Installation and Operation Guide, Chapter 1, for a CoreBuilder 5000 backplane architecture description and to the 3Com DMM Commands Guide for detailed information on DMM configuration commands.

To configure the 3Com router module:

1 Set the Token Ring speed of the targeted four CoreBuilder 5000

backplane networks.

You must set the Token Ring speed of a backplane network to match the Token Ring speed of the Cisco interface you intend to connect to the backplane network.

In the following example, Token Ring backplane network 9 is set to 4 Mbps, the same speed at which the Cisco interface port was set.

CB50 00> s et network token_ring toke n_ring_9 r ing_speed 4mbps

Value set to 4 MBPS.

2 Connect each of the router ports to one of the 10 CoreBuilder 5000

backplane networks (or set the port to isolated mode).

3-6 CHAPTER 3: CONFIGURING THE MODULE

You cannot set more than one router port to any one backplane network.

In the following example, 3Com router port 1 (Cisco interface 0) is set to backplane network 9:

CB50 00> set port 7.1 network token_ring_9 Port 07 .01 networ k id set to T OKEN_RING _9.

At this point, the system may display a sequence of RESET messages at the Cisco router management terminal. This is a normal, temporary condition that ends when the interface successfully connects to the backplane network.

3 Save the configuration:

CB50 00> save all

Failure to save configuration settings may result in loss of configuration data.

Correcting Operating Malfunctions

Table 5-1 Troubleshooting Malfunctions

Table 5-1 lists the symptoms, possible causes and corrective actions of

operating malfunctions for the CoreBuilder 5000 Network Router Module.

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

Ensure that power mode is enabled for the slot.

enabled for 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 CHAPTER 5: TROUBLESHOOTING

Table 5-1 Troubleshooting Malfunctions (continued)

Symptom Possible Cause Corrective Action

The terminal fails to respond to commands entered at the keyboard

The terminal is not receiving commands.

The keyboard cable is attached incorrectly.

Cables are not the correct type.

The console port is malfunctioning.

Power off the terminal, wait 30 seconds, and then power on again.

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.

Make sure that the cable attached to the terminal conforms to the specification. Refer to

Appendix B

Check the state of the LEDs on the front of the module. If the LEDs indicate a problem, contact your supplier for assistance.

for cabling specifications.

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 Ta bl e 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 0x2 141

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.

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:

--- Sys tem Configuration Dia log ---

8 Enter No in response to the system configuration dialog prompts until

the following system message appears:

Press R ETURN 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 (bo ot)#

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:

rout er# configure terminal Enter s ystem configuration comma nds, one per line.

Edit with DE LETE, CTRL /W, and CT RL/U; end with CTRL/Z

config -reg 0xYYYY

where Y YYY is the value noted in step 3

14 Reboot the router and use the recovered password.

Refer to Appendix C

for more information about the virtual

configuration register.

VIRTUAL CONFIGURATION

The 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 APPENDIX C: 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 value of 0x2102 is a combination of settings.

Table C-1 Virtual Configuration Register Bit Values

Bit No.

00 to 03 0x0000 to

06 0x0040 Causes system software to ignore NVRAM

07 0x0080 OEM bit enabled 08 0x0100 Break function disabled 09 — Unused 10 0x0400 IP broadcast with all zeros 11 to 12 0x0800 to

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

*The factory-default value for the configuration register is 0x2102. This value is a

combination 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.

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 [tft p] flash I J09140Z

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:

rout er# configure terminal Enter confi guration c ommands, one per line . Edit with DE LETE, CTRL /W, and CT RL/U; end with CTRL/Z

config-regi ster 0x10 2 boot sy stem flash IJ09140Z ^Z

router#

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 APPENDIX C: VIRTUAL CONFIGURATION REGISTER

A boot system configuration command in the router module configuration in NVRAM overrides the default netboot filename.

Table C-3 Default Boot Filenames

Action/ Filename

bootstrap mode 0 0 0 0 ROM software 0 0 0 1 cisco2-4500 0 0 1 0 cisco3-4500 0 0 1 1 cisco4-4500 0 1 0 0 cisco5-4500 0 1 0 1 cisco6-4500 0 1 1 0 cisco7-4500 0 1 1 1 cisco10-4500 1 0 0 0 cisco11-4500 1 0 0 1 cisco12-4500 1 0 1 0 cisco13-4500 1 0 1 1 cisco14-4500 1 1 0 0 cisco15-4500 1 1 0 1 cisco16-4500 1 1 1 0 cisco17-4500 1 1 1 1

Bit 3 Bit 2 Bit 1 Bit 0

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 Protocol

Broadcast Address

Engine Management

Terminal Baud Rate

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. Ta b le C -4

lists the combined effect

of bits 10 and 14.

Table C-4 Broadcast Address Destination Settings

Bit 14 Bit 10 Address (<net> <host>)

Off Off <ones> <ones> Off On <zeros> <zeros> On On <net> <zeros> On Off <net> <ones>

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.

Baud Bit 12 Bit 11

9600 0 0 4800 0 1 1200 1 0 2400 1 1

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 APPENDIX C: 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.

rout er> enable Passwo rd: rout er#

2 At the privileged-level system prompt (router#), enter the CONFIGURE

TERMINAL command. The system displays information about the configuration commands.

rout er# configure terminal Enter confi guration c ommands, one per line . Edit with DE LETE, CTRL /W, and CT RL/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-regi ster 0xyy yy

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:

Configurati on regist er is 0x14 2 (will be 0x102 at nex t reload)

Enabling Booting From Flash Memory C-7

6 Reboot the router module engine. The new value takes effect.

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:

rout er# configure terminal Enter confi guration c ommands, one per line . Edit with DE LETE, CTRL /W, and CT RL/U; end with CTRL/Z

boot sy stem 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:

rout er# configure terminal Enter confi guration c ommands, one per line . Edit with DE LETE, CTRL /W, and CT RL/U; end with CTRL/Z

config-reg 0x2102 ^Z
