Verifying the Primary and Backup Chassis Configuration
This section describes how to compare the ICSR configuration on both chassis.
Step 1
Enter the show configuration srp command on both chassis (Exec mode).
Verify that both chassis have the same SRP configuration information. The output looks similar to following:

Configuring Subscriber State Management Audit Process
This audit is to ensures that two ICSR peers are in synch and identifies any discrepancies prior to any scheduled or
unscheduled switchover events.
unscheduled switchover events.
Step 1
Enter the SRP Context mode and enter the service-redundancy-protocol command.
Step 2
Enter the audit daily-start-time command. Specify the daily start time as an hour and minute. For example, a start time
of 06 00 indicates that the audit will begin at 6:00 AM.
of 06 00 indicates that the audit will begin at 6:00 AM.
Step 3
Enter the audit periodicity command. Specify the interval in minutes for generating SRP audit statistics as an integer
from 60 through 1440. For example, a periodicity of 90 indicates that SRP audit statistics will be generated every 90
minutes beginning at the specified start time. Default = 60.
