Displaying information about stack failover

Use the show stack failover command to view information about rapid failover.The show stack failover command provides
information on the current standby controller and its status as shown in the following example.
device# show stack failover
Current standby is unit 2. state=ready
Standby u2 - protocols ready, can failover

Displaying hitless stacking status

The show stack command indicates whether hitless stacking is enabled. The following example shows that hitless stacking is
disabled.
ICX7750-26Q Router(config-unit-1)# show stack

Displaying pending device roles

When hitless stacking is disabled, a priority change triggers an election, but the newly-elected winner does not assume its role
until the entire stack is reloaded or hitless stacking is enabled. You can use the show stack command to view pending device
roles. The "Role" column displays the current role for each unit. The "Comment" column displays the role that will take effect after
a reload or when hitless stacking is enabled.
ICX7750-26Q Router(config-unit-1)# show stack
T=17m47.9: alone: standalone, D: dynamic cfg, S: static
ID Type
1 S ICX7750-26QXG active

3 D ICX7750-26QXG standby cc4e.2438.7500 200 remote

Displaying information about link synchronization status

Use the show stack link-sync status command to view the status of the link synchronization.
