Enabling Session Recovery on an Out-of-Service System

The following procedure is for a system that does not have any contexts configured.

To enable the session recovery feature on an out-of-service system, follow the procedure below. This procedure assumes that you begin at the Exec mode prompt.

Procedure


Step 1

At the Exec mode prompt, verify that the session recovery feature is enabled via the session and feature use licenses on the system by running the show license info command.

If the current status of the Session Recovery feature is Disabled, you cannot enable this feature until a license key is installed in the system.

Step 2

Use the following configuration example to enable session recovery.

configure 
   require session recovery 
   end 
Note

After you configure this command, you must save the configuration and then reload the chassis for the command to take effect. For information on saving the configuration file and reloading the chassis, refer to the System Administration Guide for your deployment.

Step 3

Save your configuration as described in Verifying and Saving Your Configuration.

The system, when started, enables session recovery, creates all mirrored "standby-mode" tasks, and performs packet processing card reservations and other operations automatically.

Step 4

After the system has been configured and placed in-service, you should verify the preparedness of the system to support this feature as described in Viewing Session Recovery Status section.
