Standby unit 2: protocols ready, can failover or manually switch over
Current stack management MAC is 0000.0000.1100
NOTE
The text “can failover or manually switch over” was added for hitless stacking failover and switchover.
Displaying information about stack failover
Use the show stack failover command to view information about rapid failover.
Displaying information about link synchronization status
Use the show stack link-sync status command to view the status of the link synchronization. The
following command output is from an ICX 6610 device.
