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.

Step 8

 

 

Router# copy running-config startup-config

Saves the configuration changes to your startup

 

 

configuration in NVRAM so the router boots with the

 

 

configuration you have entered.

Step 9

 

 

Router# hw-module sec-cpu reset

Resets and reloads the standby RSP with the

 

 

specified Cisco IOS image and executes the image.

 

 

Note If you do not specify a Cisco IOS image in

 

 

Step 2, this command loads and executes the

 

 

bundled default IOS standby image. The

 

 

system then operates in HSA mode.

Step 10

 

 

Router# redundancy force-switchover

Forces a switchover to the standby RSP.

 

 

 

1.Before you copy a file to Flash memory, be sure there is ample space available in Flash memory. Compare the size of the file you are copying to the amount of available Flash memory shown. If the space available is less than the space required by the file you will copy, the copy process will continue, but the entire file will not be copied into Flash memory.

Fast Software Upgrade Example

The following example show a Fast Software Upgrade performed on a Cisco 7507 router with an active RSP in slot 2 and a standby RSP installed in slot 3.

Router# copy tftp slot0:rsp-pv-mz

Router# copy tftp slaveslot0:rsp-pv-mz

Router# configure terminal

Router(config)# hw-module slot 2 image slot0:rsp-pv-mz

Router(config)# hw-module slot 3 image slot0:rsp-pv-mz

Router(config)# end

Router# hw-module sec-cpu reset

Router# copy running-config startup-config

Router# redundancy force-switchover

Configuring SLCR

The Cisco 7500 SLCR feature is disabled by default. Therefore, the process for disabling this feature is only necessary if the Cisco 7500 SLCR feature has been enabled by the user on the Cisco 7500 series router.

Enabling SLCR

To enable the Cisco 7500 Single Line Card Reload (SLCR) feature, use the service single-slot-reload-enableglobal configuration command on the Cisco 7500 series router.

 

Command

Purpose

 

 

 

 

 

 

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

Enables single line card reloading for all of the line cards in the

 

 

 

 

 

Cisco 7500 series router.
