Command Changes
guard-timer
This new SRP Configuration mode command configures the redundancy-guard-period and monitor-damping-period for
SRP service monitoring.
SRP service monitoring.
Use these guard timers to ensure that local failures, such as card reboots and task restarts, do not result in ICSR events
which can be disruptive.

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
