Command History
Usage Guidelines Enter this command with the cluster timer global configuration command only on the cluster command
switch. The cluster command switch propagates the values to all its cluster members so that the setting
is consistent among all switches in the cluster.
The holdtime is typically set as a multiple of the interval timer (cluster timer). For example, it takes
(holdtime-in-secs divided by the interval-in-secs) number of heartbeat messages to be missed in a row
to declare a switch down.
Examples This example shows how to change the interval timer and the duration on the cluster command switch.
Switch(config)# cluster timer 3
Switch(config)# cluster holdtime 30
You can verify your settings by entering the show cluster privileged EXEC command.
