Configuring a Stateful Switchover (SSO)

To configure SSO, 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-numberimage 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.

 

 

slot-number—Specifies the active 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.

 

 

file-spec—Indicates the Flash device and the

 

 

name of the image on the active RSP.

 

 

Note Step 2 and Step 3 are the same; Step 2

 

 

applies to the active RSP and Step 3

 

 

applies to the standby RSP.

 

 

Note The image indicated by the file-spec

 

 

attribute must be available on the local

 

 

Flash device. Remote protocols such a

 

 

TFTP and remote copy are not available.
