Usage Guidelines
Enter this command with the cluster holdtime 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 heartbeat 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 heartbeat 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.
