To cause the maser unit to failover to the standby unit, click Initiate Failover.
The failover results in a warm restart of the management unit in the stack.
Initiating a failover reloads the management unit in the stack, triggering the
backup unit to take over.
NOTE: The OSPF feature uses NSF to enable the hardware to continue forwarding
IPv4 packets using OSPF routes while a backup unit takes over the management
unit in the stack responsibility. To configure NSF on a stack that uses OSPF or
OSPFv3, see "NSF OSPF Configuration" on page 1290 and "NSF OSPFv3
Configuration" on page 1307.
