Cisco 7500 Series Line Card Configuration Commands


This chapter contains Cisco IOS software commands used to configure characteristics for Cisco 7500 series line cards. Line cards are any I/O card that can be inserted in a modular chassis (including the Cisco 7500 RSP cards).

For more information on Cisco 7000 series hardware configuration, see the Core/High-End Routers documentation section of Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/core/index.htm or on the Documentum CD-ROM.

service single-slot-reload-enable

To enable single line card reloading for all line cards in a Cisco 7500 series router, use the service single-slot-reload-enable global configuration command. To disable single line card reloading for the line cards, use the no form of this command.

service single-slot-reload-enable

no service single-slot-reload-enable

Syntax Description

This command has no arguments or keywords.

Defaults

Single line card reloading is disabled by default.

Usage Guidelines

Before the introduction of this command, the only method of correcting a line card hardware failure or a severe software error for one line card on a Cisco 7500 series router required the execution of a Cbus Complex, a process that reloaded every line card on the network backplane. The time taken to complete the Cbus Complex was often inconvenient, and no network traffic could be routed or switched during the Cbus Complex process.

The service single-slot-reload-enable command allows users to correct a line card failure on a Cisco 7500 series router by reloading the failed line card without reloading any other line cards on the network backplane. During the single line card reload process, all physical lines and routing protocols on the other line cards of the network backplane remain active. A single line card reload is also substantially faster than the Cbus Complex process

Examples

In the following example, single line card reloading is enabled for all lines cards on a Cisco 7513 router:

c7513(config)# service single-slot-reload-enable

slave auto-sync config

To turn on automatic synchronization of configuration files for a Cisco 7507 or Cisco 7513 router that is configured for High System Availability (HSA) using Dual RSP Cards, use the slave auto-sync config global configuration command. To turn off automatic synchronization, use the no form of the command.

slave auto-sync config

no slave auto-sync config

The command was introduced.


Usage Guidelines

Use this command for a Cisco 7507 or Cisco 7513 router that is configured for dual RSP cards. On the Cisco 7507 and Cisco 7513 router, you can install two RSP cards in a single router to improve system availability. Dual RSP Cards is a High System Availability (HSA) feature.

In automatic synchronization mode, when you issue a copy EXEC command that specifies the master's startup configuration (nvram:startup-config) as the target, the master also copies the same file to the slave's startup configuration (slavenvram:startup-config). Use this command when implementing HSA for simple hardware backup or for software error protection to ensure that the master and slave RSP contain the same configuration files.

Examples

The following example turns on automatic configuration file synchronization. When the copy system:running-config nvram:startup-config command is entered, the running configuration is saved to the startup configurations of both the master RSP and the slave RSP.

Router(config)# slave auto-sync config
Router(config)# end
Router# copy system:running-config nvram:startup-config

Related Commands

Command
Description

show controller cbus

Displays detailed information on the cards connected to the CBus controller.

show stacks

Displays the stack trace and version information of the master and slave RSP cards.

show version

Displays the software version running on the master and slave RSP cards.

slave sync config

slave default-slot

To specify the default slave Route Switch Processor (RSP) card on a Cisco 7507 or Cisco 7513 router, use the slave default-slot global configuration command.

slave default-slot processor-slot-number

Syntax Description

processor-slot-number

Number of a processor slot that contains the default slave RSP. On the Cisco 7507 router, valid values are 2 or 3. On the Cisco 7513 router, valid values are 6 or 7. The default is the higher number processor slot.


Defaults

The default slave is the RSP card located in the higher number processor slot. On the Cisco 7507 router, processor slot 3 contains the default slave RSP. On the Cisco 7513 router, processor slot 7 contains the default slave RSP.

Usage Guidelines

Use this command for a Cisco 7507 or Cisco 7513 router that is configured for Dual RSP Cards. On the Cisco 7507 and Cisco 7513 router, you can install two RSP cards in a single router to improve system availability. Dual RSP Cards is a High System Availability (HSA) feature.

The router uses the default slave information when booting as follows:

If a system boot is due to powering up the router or using the reload EXEC command, then the specified default slave will be the slave RSP.

If a system boot is due to a system crash or hardware failure, then the system ignores the default slave designation, and makes the crashed or faulty RSP card the slave RSP.

Examples

In the following example, the user sets the default slave RSP to processor slot 2 on a Cisco 7507 router:

c7507(config)# slave default-slot 2

slave image

To specify the image that the slave Route Switch Processor (RSP) runs on a Cisco 7507 or Cisco 7513 router, use the slave image global configuration command.

slave image {system | file-url}

Syntax Description

system

Loads the slave image that is bundled with the master system image. This is the default.

file-url

Loads the slave image from the specified file in a Flash file system. If you do not specify a filename, the first file on the specified Flash file system is the default file.


Defaults

The default is to load the image from the system bundle.

Usage Guidelines

Use this command for a Cisco 7507 or Cisco 7513 router that is configured for Dual RSP Cards. On the Cisco 7507 and Cisco 7513 router, you can install two RSP cards in a single router to improve system availability. Dual RSP Cards is a High System Availability (HSA) feature.

Use the slave image command to override the slave image that is bundled with the master image.

When using HSA for simple hardware backup, ensure that the slave image is in the same location on the master and the slave RSP card. Thus, if the slave RSP card becomes the master, it will be able to find the slave image and download it to the new slave.

Examples

In the following example, the slave RSP is specified to run the rsp-dw-mz.ucode.111-3.2 image from slot 0:

c7507(config)# slave image slot0:rsp-dw-mz.ucode.111-3.2
