Cisco ASR 5500 System Administration Guide

Initiating an SRP Switchover
An SRP switchover places the primary chassis in standby mode and makes the backup chassis active. The
secondary chassis is now processing sessions with the upgraded software.
Step 1
On the primary chassis run the srp initiate-switchover command. All existing sessions will be migrated to the backup
chassis and it begins servicing new session requests. Allow the switchover process to complete.
Step 2
On the primary chassis, run the show srp info command. Chassis State should indicate Standby when switchover is
complete.
Step 3
On the backup chassis, confirm the switchover is complete by running the show srp info command. Chassis State should
indicate Active when switchover is complete.
Checking AAA Monitor Status on the Newly Active System
If your network deployment requires communication with AAA servers, log into the newly active system and
perform an AAA monitor check. You will be checking for the existence of any SNMP traps that indicate the
system cannot communicate with AAA servers (starSRPAAAUnreachable).
Step 1
Run the Exec mode command show snmp trap history |grep starSRPAAAUnreachable.
Step 2
There should be no output for this command, or no very recent SNMP trap notifications (based on the event timestamp).
Step 3
If the active system cannot communicate with one or more AAA servers, refer to AAA Monitor for additional information.
