Hitless stacking failover

Hitless stacking failover provides automatic failover from the active controller to the standby controller without resetting any of
the units in the stack and with little or no packet loss to hitless stacking-supported services and protocols.
For a description of the events that occur during a hitless failover, refer to
failover on page 176.
For a description of this feature's impact on major system functions, refer to

Enabling hitless stacking failover

NOTE
Hitless stacking failover is enabled by default in FastIron release 08.0.20 and later releases.
To enable hitless stacking failover, enter the following command at the global CONFIG level of the CLI:
device# configure terminal
device(config)# hitless-failover enable
The command takes effect immediately. Hitless switchover is allowed, and in the event of a failover, the standby controller takes
over the active role without reloading the stack.
