seconds between heartbeat messages. Use the no form of this command to return to the default setting.

Command Modes Global configuration
Command History Release

Usage Guidelines Use this command with the cluster holdtime global configuration command only on the command
switch. The 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 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.
