Initiating an SRP Switchover
This SRP switchover places the primary system in active mode and returns the backup system to the standby.
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 which begins servicing new session requests. Allow the switchover process to complete.
Step 2
On the backup system, run the show srp info command. Chassis State should indicate Standby when switchover is
complete.
Step 3
On the primary system, 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.
