Interchassis Session Recovery

Configuring Subscriber State Management Audit Process

This audit ensures that two ICSR peers are in synch and identifies any discrepancies prior to any scheduled
or unscheduled switchover events.
Step 1 Enter the SRP Context mode and then 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.
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.
A sample configuration sequence appears below.

context ctx_name

audit periodicity 90

Troubleshooting ICSR Operation

SSD
StarOS supports an ICSR-specific show support details (SSD) command that outputs the results from a series
of Exec mode show commands.This mini SSD reduces capture time when debugging ICSR timing issues
between the Active and Standby chassis, facilitating quicker resolution of the problem.
The show support details icsr command produces a mini SSD that contains the output of the following show
commands:
• show srp info
• show srp checkpoint statistics
• show srp checkpoint statistics verbose
• show srp checkpoint statistics debug-info
• show srp checkpoint statistics sessmgr all
• show srp checkpoint statistics sessmgr all debug-info
• show srp checkpoint statistics ipsecmgr all
• show srp checkpoint statistics sessmgr all write-list-stats
