Installation Prerequisites Installation Prerequisites Before beginning the installation procedures, review the following sections to ensure awareness of the appropriate regulatory and safety requirements, and to ensure that your RSP8 hardware functions properly with compatible components: Note • Safety Guidelines, page 10 • Compatibility Requirements, page 13 • List of Parts and Tools, page 15 If you are replacing an existing RSP8, back up your current configuration file to a remote server before y
Installation Prerequisites Attention Ce symbole d'avertissement indique un danger. Vous vous trouvez dans une situation pouvant causer des blessures ou des dommages corporels. Avant de travailler sur un équipement, soyez conscient des dangers posés par les circuits électriques et familiarisez-vous avec les procédures couramment utilisées pour éviter les accidents.
Installation Prerequisites Electrical Equipment Guidelines Follow these basic guidelines when working with any electrical equipment: • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. • Disconnect all power and external cables before moving a chassis. • Do not work alone when potentially hazardous conditions exist. • Never assume that power has been disconnected from a circuit; always check.
Installation Prerequisites Caution • When you remove a processor module, place it component-side-up on an antistatic surface or in a static shielding bag. Immediately place the module in a static shielding bag if you need to return it to the factory. • Avoid contact between electronic equipment and clothing. Antistatic straps only protect the equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Installation Prerequisites – 12.1(0) or a later release of Cisco IOS Release 12.1 – 12.1(2)E or a later release of Cisco IOS Release 12.1 E Note You can reboot from a Flash memory card or Flash Disk in the RSP8 that was previously formatted on an RSP4+. • You must first reformat the Flash memory card or Flash Disk on an RSP8, that was previously formatted on one of these other RSP-based systems, before you can use it as a boot or storage source with the RSP8.
Installation Prerequisites Caution Before using a Flash memory card previously formatted and used in an RSP, RSP7000, RSP1, RSP2, or RSP4, you must reformat the Flash memory card. Flash memory cards formatted on any of these processors do not work properly in an RSP8. You must first reformat it on your RSP8 system. Refer to Flash Memory Card Installation Instructions for instructions on reformatting Flash memory. You must also format any flash disk for the RSP8 on an RSP8.
Installing the RSP8 Installing the RSP8 Before you begin, be sure that your system meets the minimum software, hardware, and microcode requirements described in the “Compatibility Requirements” section on page 13.
Installing the RSP8 Step 3 If you are replacing the RSP8, disconnect any devices that are attached to the console or auxiliary ports. If you are removing the RSP8 for maintenance and will reinstall the same one, you can leave the devices attached provided that doing so will not strain the cables. Step 4 Use a screwdriver to loosen the two captive installation screws. (See Figure 3.
Installing the RSP8 Step 7 Place the removed RSP8 on an antistatic mat or foam. If you plan to return the RSP8 to the factory, immediately place it in an antistatic bag to prevent ESD damage. Step 8 Attach the equipment end of the ESD-preventive strap to the RSP8 before performing any maintenance on the RSP8 that might create an ESD hazard. This completes the removal procedure. If you removed the RSP8 to replace DIMMs, proceed to the “Replacing and Upgrading DRAM DIMMs” section on page 74.
Installing the RSP8 Handling the RSP8 During Removal and Installation H1355a Figure 4 Caution To prevent damage to the backplane, you must install the RSP8 in one of the two RSP slots on the router. The slots are keyed for correct installation. Forcing the RSP8 into a different slot can damage the backplane and the RSP8. Step 3 While keeping the RSP8 parallel to the backplane, carefully slide the carrier into the slot until the RSP8 faceplate makes contact with the ejector levers, and then stop.
Installing the RSP8 Connecting a Console Terminal The system console port on the RSP8 is a DB-25 receptacle DCE port for connecting a console terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP8 just below the auxiliary port, as shown in Figure 5, and is labeled Console. Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you are using.
Installing the RSP8 Note The Y-cables are not required; two individual console cables and two individual auxiliary cables can be used instead. Figure 6 shows the console Y-cable and Figure 7 shows the auxiliary Y-cable.
Installing the RSP8 Step 3 For a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX with HSA or HA configured, verify that the console terminal displays the system banner and startup screen as the system restarts. • The active console display should look similar to the following for a Cisco 7513 and Cisco 7513-MX (note the RSP slots indicated): System Bootstrap, Version 11.1, RELEASED SOFTWARE Copyright (c) 1986-1999 by cisco Systems, Inc.
Installing the RSP8 Step 6 Verify that all the enabled LEDs (on the interface processors) are on. Step 7 In systems with a second RSP8 installed (and HSA or HA configured), use the show version command to verify that the standby RSP8 is recognized by the system. Following is a sample from a Cisco 7513: Router> show version Cisco Internetwork Operating System Software IOS (tm) RSP Software (RSP-JSV-M), Version 11.1 [biff 51096] Copyright (c) 1986-1999 by cisco Systems, Inc.
Configuring the Router for a Single RSP8 Configuring the Router for a Single RSP8 If you have a single RSP8, you can configure your system according to the Cisco IOS release appropriate for your router. See the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware at http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm.
Configuring High System Availability Configuring High System Availability This section describes high system availability (HSA), a feature that enables a router to continue processing and forwarding packets after a planned or unplanned outage.
Configuring High System Availability If a system crash causes the active RSP8 to fail, the standby RSP8 becomes the new active RSP8 and uses its own system image and configuration file to reboot the router. The failed RSP8 card (now the standby) remains inactive until you perform diagnostics, correct the problem, and then issue the standby reload command.
Configuring High System Availability HSA System Requirements To configure HSA operation with the RSP8, you must have: Caution • A Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX containing one RSP active processor card, one RSP standby processor card, and the proper Cisco IOS release (refer to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl for additional information). • A standby RSP with the same (or higher) DRAM and Flash memory capacity as the active RSP.
Configuring High System Availability Specifying the Default Standby RSP Your view of the environment is always from the active RSP8 perspective, and you must define a default standby RSP8. The router uses the default standby information when booting. • If a system boot is due to powering up the router or using the reload command, then the specified default standby is the standby RSP8.
Configuring High System Availability Automatic synchronization mode is on by default; however, to turn it on manually, use the following commands beginning in privileged EXEC configuration mode: Command Purpose Step 1 Router# configure terminal Enters global configuration mode. Step 2 Router(config)# slave auto-sync config Enables automatic synchronization mode. Step 3 Router(config)# end Exits global configuration mode.
Configuring High System Availability Note Standard 16-, 20-, or 32-MB Flash memory cards are supported with the RSP8. (The 20-MB Flash memory card is currently the default.) See Flash Memory Card Installation Instructions for detailed information. You should specify slot0 or slot1 in your command, depending on which slot you are using. Standard 48-MB, 64-MB, and 128-MB Flash Disks are supported with the RSP8. See Using the Flash Disk for additional information.
Configuring High System Availability Command Purpose Step 3 Router# dir {slavebootflash: | slaveslot0: | slaveslot1:} Determines whether the standby RSP contains the same microcode image in the same location. Step 4 Router# copy {bootflash:[filename] | slot0:[filename] | slot1:[filename]} {slavebootslot:[filename] | slaveslot0:[filename] | slaveslot1:[filename]} Copies the active’s system image to the appropriate standby location.

Configuring High System Availability Figure 8 illustrates the software error protection configuration for this sample scenario. The commands to set up this configuration follow the figure.
Configuring High System Availability Step 4 Enter global configuration mode and configure the system to boot first from a Cisco IOS Release 12.0(22.3)S1 system image and then from a Cisco IOS Release 12.0(23)S system image. Router# configure terminal Router(config)# boot system flash slot0:rsp-pv-mz.120-22.3.S1 Router(config)# boot system flash slot0:rsp-pv-mz.120-23.S With this configuration, when the slot 6 RSP is active, it looks first in its PC Card slot 0 for the system image file rsp-pv-mz.120-22.
Configuring High System Availability In this scenario, we begin with the configuration shown in Figure 9. Figure 9 Software Error Protection—Backing Up with an Older Software Version, Part I NA NA L L EN AB LE L L AN B A L L AE AE AN B AN AN BA B E AE AL AL EN AB EE LE EE A A NLE NLE Next, we copy the rsp-pv-mz.120-23.S image to the active and the standby RSPs, as shown in Figure 10.
Configuring High System Availability Last, we delete the rsp-pv-mz.120-22.3.
Configuring High System Availability Step 4 Configure the system to boot first from a Cisco IOS Release 12.0(22.3)S1 system image and then from a Cisco IOS Release 12.0(23)S system image: Router# configure terminal Router(config)# boot system flash slot0:rsp-pv-mz.120-22.3.S1 Router(config)# boot system flash slot0:rsp-pv-mz.120-23.S Step 5 Configure the system further with a fault-tolerant booting strategy: Router(config)# boot system tftp rsp-pv-mz.120-23.S 10.1.1.
Configuring High System Availability However, automatic synchronization is enabled by default on the RSP. Therefore, unless you have disabled automatic synchronization, or this is the first time you are installing a second RSP, a manual update is not required. For more information about automatic synchronization, see the “Ensuring that Both RSPs Contain the Same Configuration Files” section on page 28.
Configuring High System Availability You do not need to use the slave sync config command when automatic synchronization is enabled, unless this is the first time you are installing a second RSP. For more information about this use of the slave sync config command, see the “Monitoring and Maintaining HSA Operation” section on page 40. Note Automatic synchronization mode is on by default. Therefore, unless you have disabled automatic synchronization a manual update is not required.
Enabling High Availability Features You can manually synchronize configuration files and ROM monitor environment variables on the active and the standby RSPs using the following command in privileged EXEC configuration mode: Caution Command Purpose Router# slave sync config Manually synchronizes active and standby configuration files. When you install a second RSP for the first time, you must immediately configure it using the slave sync config command.
Enabling High Availability Features SLCR is disabled by default and needs to be manually configured. When SLCR is enabled, and more than two linecards crash simultaneously, all line cards will be reset. For more information on how to configure SLCR, refer to the Cisco 7500 Single Line Card Reload feature module at http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s13 /slcr.htm.
Enabling High Availability Features • Cisco Nonstop Forwarding (NSF) —Used with SSO, NSF allows routers with redundant RSPs to continue forwarding data to the standby RSP during a switchover. This feature uses the Forwarding Information Base (FIB) that was current at the time of the switchover. Once the routing protocols have converged, the FIB table is updated and stale route entries are deleted. This feature eliminates downtime during the switchover. Note: Cisco NSF always runs together with SSO.
Enabling High Availability Features Enabling the Router To enter privileged EXEC configuration mode, enable the router using the following steps: Step 1 At the user-level EXEC prompt, run the enable command. The router prompts you for a privileged-level password as follows: Router> enable Password: Step 2 Type the password (the password is case sensitive). For security purposes, the password is not displayed.
Enabling High Availability Features To copy a Cisco IOS software image from a TFTP server to a Flash memory card or Flash Disk on the active RSP, use the following commands beginning in privileged EXEC configuration mode: Step 1 Command Purpose Router# copy tftp slotslot-number: Uses TFTP to copy a high availability Cisco IOS image onto the Flash memory card or Flash Disk of the active RSP.1 • Address or name of remote host []? ip-address The router prompts you for the IP address of the TFTP server.
Enabling High Availability Features Setting the Config-Register Boot Variable Though it is not required, we recommend that you modify the software configuration register boot field so that the system boots the same image that the hw-module slot slot-number image file-spec command specifies in the “Configuring RPR and RPR+” section on page 46. Command Purpose Step 1 Router# show version Obtains the current configuration register setting.
Enabling High Availability Features To configure RPR and RPR+, use the following commands beginning in privileged EXEC configuration mode: Command Purpose Step 1 Router# configure terminal Enters global configuration mode. Step 2 Router(config)# hw-module slot slot-number image file-spec Specifies the image to be used by the active RSP at initialization. If a high-availability image is found, the running configuration is updated.
Enabling High Availability Features Verifying RPR and RPR+ Use the show redundancy command to verify that RPR or RPR+ is enabled: Router# show redundancy Operating mode is sso redundancy mode sso hw-module slot 6 image disk0:rsp-pv-mz hw-module slot 7 image disk0:rsp-pv-mz Active High Availability version is 3.0 Standby High Availability version is 3.0 Active in slot 6 Standby in slot 7 The system The system The system Reason for total uptime since last reboot is 2 weeks, 23 hours 41 minutes.

Enabling High Availability Features Step 3 Command Purpose Router(config)# hw-module slot slot-number image file-spec Specifies the image to be used by the standby RSP at initialization. If a high-availability image is found, the running configuration is updated. • slot-number—Specifies the standby RSP slot where the Flash memory card or Flash Disk is located. Valid numbers are slot 2 or slot 3 for a Cisco 7507 router or slot 6 or slot 7 for a Cisco 7513 router.
Enabling High Availability Features Note Step 1 The output of these commands will vary based on your device configuration and system site requirements. Use the show redundancy command to verify that SSO is configured on the device. Router# show redundancy Operating mode is sso redundancy mode sso hw-module slot 6 image disk0:rsp-pv-mz hw-module slot 7 image disk0:rsp-pv-mz Active High Availability version is 3.0 Standby High Availability version is 3.
Enabling High Availability Features Configuring Nonstop Forwarding (NSF) Cisco Nonstop Forwarding (NSF) always runs together with SSO. If you have not already configured SSO, refer to the “Configuring a Stateful Switchover (SSO)” section on page 49. Cisco NSF is supported by the BGP, OSPF, and IS-IS protocols for routing and by Cisco Express Forwarding (CEF) for forwarding.
Enabling High Availability Features To configure BGP for NSF, use the following commands beginning in privileged EXEC configuration mode, and repeat this procedure on each of the BGP NSF peer devices: Command Purpose Step 1 Router# configure terminal Enters global configuration mode. Step 2 Router(config)# router bgp as-number Enables a BGP routing process, and enters router configuration mode.
Enabling High Availability Features Command Step 3 Purpose Router(config-router)# nsf [cisco | ietf] Enables NSF operation for IS-IS. Use the ietf keyword to enable IS-IS in homogeneous network where adjacencies with networking devices supporting IETF draft-based restartability is guaranteed. Use the cisco keyword to run IS-IS in heterogeneous networks that might not have adjacencies with NSF-aware networking devices.
Enabling High Availability Features Expanded LC ipc memory: 0 Kbytes Linecard reloader type: aggressive (Default) RRP state: I am standby RRP: no RF Peer Presence: yes RF PeerComm reached: yes Redundancy mode: sso(7) CEF NSF: enabled/running Verifying BGP NSF To verify NSF for BGP, you must check that the graceful restart function is configured on the SSO-enabled networking device and on the neighbor devices.
Enabling High Availability Features Verifying OSPF NSF To verify NSF for OSPF, you must check that the NSF function is configured on the SSO-enabled networking device. Perform the following steps: Step 1 Verify that “nsf” appears in the OSPF configuration of the SSO-enabled device by entering the show running-config command: Router# show running-config router ospf 120 log-adjacency-changes nsf network 192.168.20.0 0.0.0.255 area 0 network 192.168.30.0 0.0.0.255 area 1 network 192.168.40.0 0.0.0.
Enabling High Availability Features RP is ACTIVE, standby ready, bulk sync complete NSF interval timer expired (NSF restart enabled) Checkpointing enabled, no errors Local state:ACTIVE, Peer state:STANDBY HOT, Mode:SSO The following display shows sample output for the Cisco configuration on the standby RSP.
Enabling High Availability Features Troubleshooting NSF Features To troubleshoot the NSF feature, use the following commands in privileged EXEC configuration mode, as needed: Command Purpose Router# clear cef epoch Begins a new epoch and increments the epoch number for a CEF table. Router# debug isis nsf [detail] Displays information about the IS-IS state during a Cisco NSF restart. Router# debug ospf nsf [detail] Displays debugging messages related to OSPF Cisco NSF commands.
Enabling High Availability Features BGP NSF Configuration Example The following example configures BGP NSF on a networking device: Router# configure terminal Router(config)# router bgp 590 Router(config-router)# bgp graceful-restart BGP NSF Neighbor Device Configuration Example The following example configures BGP NSF on a neighbor router. All devices supporting BGP NSF must be NSF-aware, meaning that these devices recognize and advertise graceful restart capability.
Enabling High Availability Features Performing a Fast Software Upgrade To perform a Fast Software Upgrade (FSU), use the following commands beginning in privileged EXEC configuration mode: Step 1 Command Purpose Router# copy tftp slotslot-number: Uses TFTP to copy a high availability Cisco IOS image onto the Flash memory card or Flash Disk of the active RSP.1 • Address or name of remote host []? ip-address The router prompts you for the IP address of the TFTP server.
Enabling High Availability Features Step 2 Router# copy tftp slotslot-number: Uses TFTP to copy a high availability Cisco IOS image onto the Flash memory card or Flash Disk of the standby RSP. • Note Address or name of remote host []? ip-address ip-address—Specifies the IP address of the TFTP server that contains the new image The router prompts you for the name of the image file you are copying to the Flash memory card or Flash Disk.
Enabling High Availability Features Step 6 Router(config)# slave auto-sync config (Optional) Turns on automatic synchronization of configuration files. Use this command to ensure that the active and standby RSPs contain the same configuration files. Step 7 Router(config)# end Exits global configuration mode and returns you to privileged EXEC configuration mode.
Enabling High Availability Features Disabling SLCR To disable the Cisco 7500 Single Line Card Reload feature, use the no service single-slot-reload-enable global configuration command on the Cisco 7500 series router. Command Purpose Router(config)# no service single-slot-reload-enable Disables single line card reloading for all of the line cards in the Cisco 7500 series router.
Monitoring and Maintaining the Active and Standby RSPs Monitoring and Maintaining the Active and Standby RSPs To display information about the active and the standby RSPs, use any of the following commands beginning in privileged EXEC configuration mode: Command Purpose Router# show boot var Displays the environmental variable settings and configuration register settings for the active and the standby RSPs. Router# show flash all Shows a list of Flash devices currently supported on the router.
Troubleshooting the Installation RSP8 LEDs Figure 12 shows the LEDs on the RSP8 faceplate. The LEDs on the RSP8 indicate the system and RSP8 status and which PC Card slot is active. The CPU halt LED, which goes on only if the system detects a processor hardware failure, should remain off. A successful boot is indicated when the normal LED goes on; however, this does not necessarily mean that the system has reached normal operation.
Troubleshooting the Installation Verifying System Startup Sequence By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. Because you turn on the system power with the on/off switches on each power supply, it is easiest to observe the startup behavior from the rear of the router.
Troubleshooting the Installation Step 3 When you have verified that the power supply is functioning properly, observe the LEDs on the RSP8. The CPU halt LED always turns on during initial power-up of an RSP8 and remains on for approximately one-half second, then turns off. If it remains on during the startup sequence, the system has encountered a processor hardware error. • Use the show version command to check the current configuration register settings.
Troubleshooting the Installation • Check the terminal settings to ensure that the terminal is set for 9600 baud, 8 data bits, no parity, and 2 stop bits. • If the terminal is set correctly and still fails to operate, suspect that the terminal is faulty. Connect a different terminal and restart the system. If the system still fails to start up or operate properly, or if you isolate the cause of the problem to a failed component, contact a service representative for further assistance.
Maintenance Information Step 4 Wait 15 seconds. Step 5 Reinsert the standby RSP8. This completes the procedure to remove and replace an interface processor. Reloading a Failed RSP When a new active RSP takes over ownership of the router, it automatically reboots the failed RSP as the standby RSP. You can also manually reload the failed RSP.
Maintenance Information Configuration information resides in two places when the router is operating: the startup default (permanent) configuration in NVRAM, and the running (temporary) memory in RAM. The default startup configuration always remains available; NVRAM retains the information even when the power is shut down. The current information is lost if the system power is shut down.
Maintenance Information Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds: ..... Success rate is 0 percent (0/5) Router# If the connection fails, check the physical connection to the remote file server and verify that you are using the correct address or name, and then ping the server again. If you are unable to establish a good connection, contact your network administrator or see the “Obtaining Technical Assistance” section on page 89 for instructions on contacting technical assistance.
Maintenance Information Remote host []? Step 7 Type the name or interface processor address of the remote host. In the following example, the name of the remote server is servername: Router# copy startup-config tftp Remote host []? servername Translating “servername”...domain server (10.1.1.1) [OK] Step 8 The EXEC command interpreter prompts you for the name of the file that will contain the configuration. By default, the system appends -confg to the router’s name to create the new filename.
Maintenance Information Retrieving the Configuration File This section describes how to retrieve the saved configuration and copy it to NVRAM. Enter privileged EXEC configuration mode and specify that you will configure the router from the network. The system prompts you for a host name and address, the name of the configuration file stored on the host, and confirmation to reboot using the remote file.
Maintenance Information While the router retrieves and reloads the configuration file from the remote host, the console display indicates whether or not the operation is successful. A series of exclamation points (!!!!) and [OK] (as shown in the preceding example) indicates that the operation was successful. A series of periods (...) and [timed out] or [failed] indicate a failure (which would probably be due to a network fault or an incorrect server name, address, or filename).
Maintenance Information Note The total number of memory devices per DIMM differs for each manufacturer. The DIMMs in Figure 2 are generic representations of the actual DRAM DIMMs for your RSP. Table 4 lists the various configurations of DRAM DIMMs that are available, the number of DIMMs for each configuration, and the DRAM banks they occupy. Note which banks are used, given the combinations of available DIMM sizes and the maximum DRAM you require.
Maintenance Information Removing DIMMs This section discusses the procedure for removing DIMMs from your RSP8. Use this procedure to remove the existing DIMMs: Step 1 Turn off the system power and follow the steps in the “Removing the RSP8” section on page 16. Step 2 Place the RSP8 on an antistatic mat or pad and ensure that you are wearing an antistatic device, such as a wrist strap.
Maintenance Information Step 7 Place the removed DIMM on an antistatic mat, and store it in an antistatic container to protect it from ESD damage. Step 8 Repeat Step 4 through Step 7 for the remaining DIMM, if required for your upgrade. This completes the DIMM removal procedure. Proceed to the next section to install the new DIMMs. Installing New DIMMs This section discusses the procedure for installing DIMMs on your RSP. Use this procedure to install new DIMMs. Note Do not mix memory sizes.
Maintenance Information Checking the RSP Memory Upgrade This section describes how you would verify the memory upgrade. • Observe the LED states and the console display. As the system reinitializes the interfaces, the enabled LEDs should go on. (Port adapter status LEDs might be on, depending on your connections.) The console screen also displays a message as the system discovers each interface during its reinitialization.
Maintenance Information To recover a lost password, follow these steps: Step 1 Attach an ASCII terminal to the router console port, which is located on the rear panel. Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 2 stop bits (or to whatever settings the router is set). Step 3 Use the show version command to display the existing configuration register value. Note this value for later use in Step 13. Step 4 If the Break function is disabled, power cycle the router.
Reference Information Step 9 Press Return. After some interface information, the prompt appears as follows: Router > Step 10 Use the enable command to enter privileged EXEC configuration mode. The prompt changes to the following: Router # Step 11 Use the show configuration privileged EXEC command to display the enable password in the configuration file. Step 12 At the privileged EXEC prompt, use the configure terminal command to enter global configuration mode.

Reference Information • To recover a lost password • To allow you to manually boot the system using the b command at the bootstrap program prompt • To force the router to boot automatically from the system bootstrap software (boot image) or from its default system image in onboard Flash memory, and to read any boot system commands that are stored in the configuration file in NVRAM If the router finds no boot system commands, it uses the configuration register value to form a filename from which to bo
Reference Information Changing Settings To change the configuration register while running the system software, follow these steps: Step 1 To enter privileged EXEC configuration mode, use the enable command and your password as shown: Router> enable Password: Router# Step 2 To enter global configuration mode, use the configure terminal command. You are prompted for further commands, as shown in the following example: Router# configure terminal Enter configuration commands, one per line.
Reference Information If you set the boot field value to 0x2 through 0xF and there is a valid boot system command stored in the configuration file, then the router boots the system software as directed by that value. If there is no boot system command, the router forms a default boot filename for booting from a network server. (See Table 11 for the format of these default filenames.
Reference Information Bit 8 controls the console Break key. 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, thereby halting normal operation. Regardless of the setting of the break enable bit, a break causes a return to the ROM monitor during the first few seconds (approximately 5 seconds) of booting. Bit 9 is unused.
Reference Information To disable the Break function and enable the boot system flash device:filename command, use the config-register command with the value shown in the following example: Router(config)# config-reg 0x0102 Router(config)# end Router# Enabling a Boot from the Flash Disk To enable a boot from the Flash Disk, set configuration register bits 3, 2, 1, and 0 to a value between 2 and 15 in conjunction with the boot system [disk0: | disk1:]filename configuration command.
Obtaining Documentation The config-reg 0x2102 command, with the hexadecimal value 0x2102, results in the following: Step 3 • Enables the system to boot the default boot ROM software if the Flash Disk-based image fails to boot—hexadecimal value 0x2000 • Disables Break—hexadecimal value 0x0100 • Enables the image myfile as the default boot image—hexadecimal value 0x0002 Press Ctrl-Z or type end to exit global configuration mode: System(config)# System(config)# end System# Step 4 Save the new config
