To cause the maser unit to failover to the standby unit, click Initiate Failover.
The failover results in a warm restart of the stack master. Initiating a failover
reloads the stack master, triggering the backup unit to take over.
NOTE: The OSPF feature uses NSF to enable the hardware to continue for warding
IPv4 packets using OSPF routes while a backup unit takes over stack master
responsibility. To configure NSF on a stack that uses OSPF or OSPFv3, see "NSF
OSPF Configuration" on page 1137 and "NSF OSPFv3 Configuration" on page 1154.
