Configure ICSR Switchover Guard Timer
The SRP Configuration mode guard timer command configures the redundancy-guard-period and monitor-damping-

Use these guard timers to ensure that local failures, such as card reboots and task restarts, do not result in ICSR events

Notes:
aaa-switchover-timers – sets timers that prevent back-to-back ICSR switchovers due to an AAA failure (post
ICSR switchover) while the network is still converging.
damping-period – configures a delay time to trigger an ICSR switchover due to a monitoring failure
within the guard-period.
guard-period – configures the local-failure-recovery network-convergence timer.
diameter-switchover-timers – sets timers that prevent a back-to-back ICSR switchover due to a Diameter
failure (post ICSR switchover) while the network is still converging.
damping-period – configures a delay time to trigger an ICSR switchover due to a monitoring failure
within the guard-period.
guard-period – configures the local-failure-recovery network-convergence timer.
srp-redundancy-timers – sets timers that prevent an ICSR switchover while the system is recovering from a
local card-reboot/critical-task-restart failure.
aaa – local failure followed by AAA monitoring failure
bgp – local failure followed by BGP monitoring failure
diam – local failure followed by Diameter monitoring failure
