Displaying management redundancy information
Enter the following command at any level of the CLI, to view the redundancy parameter settings and
statistics.
Brocade(config)# show redundancy
=== MP Redundancy Settings ===
Configured Active Slot = 9
Running-Config Sync Period = (upon "write mem")
=== MP Redundancy Statistics ===
Current Active Session:
Active mgmt slot = 9, Standby mgmt slot = 10 (Absent)
Switchover cause = No Switchover
Start Time = Jan 1 00:00:09
Sxr Sys Hitless Enable Status = 0
Total number of Switchover/Failovers = 0
L3 slib baseline sync status: 0 [complete]
Layer 3 hitless route purge
Layer 3 traffic is forwarded seamlessly during a failover, switchover, or OS upgrade when hitless
management is enabled.
Some protocols support non-stop routing. On enabling non-stop routing, after switchover the
management module quickly re-converge the protocol database. Whereas, some protocols support
graceful restart, in which the protocol state is re-established with the help of neighboring devices.
Once all the protocols converge the routes which were removed from the network during the
convergence period, the routes are deleted from the devices. You can set the route purge timer per
VRF instance. Configure the timer to set the duration for which the routes should be preserved
after switchover. Once this period elapses, the route purging starts, if by then all other protocols
have finished non-stop routing or graceful restart.
When switchover occurs, the route purge timer starts. If non-stop routing or graceful restart is also
configured, the route validation and purging starts only when they are complete and the purge
timer has elapsed. If for some reason more delay is expected in learning the routes, you can
configure a larger period for the purge timer.
Setting the IPv4 hitless purge timer on the defatult VRF
To configure the purge timer, enter the ip hitless-route-purge-timer command in global
configuration mode.
Example for setting IPv4 hitless purge timer
on the default VRF
The following example shows how to set the IPv4 hitless purge timer on the default VRF:
Brocade(config)# ip hitless-route-purge-timer 60
