Initiating an SRP Switchover

An SRP switchover places the primary chassis in active mode and makes the backup chassis active. The
primary chassis is now processing sessions with the upgraded software.
Step 1
On the backup chassis run the srp initiate-switchover command. All existing sessions will be migrated to the primary
chassis and it begins servicing new session requests. Allow the switchover process to complete.
Step 2 On the backup chassis, run the show srp info command. Chassis State should indicate Standby when switchover is
complete.
Step 3 On the primary chassis, confirm the switchover is complete by running the show srp info command. Chassis State should
indicate Active when switchover is complete.

Making Test Calls

Once the chassis state is verified and subscribers are migrated, perform new call testing to make sure calls
are successful.
