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.
