Cisco Cisco Gigabit Ethernet Switch Module (CGESM) for HP Technical References

Use the cluster timer global configuration command to set the interval in seconds between heartbeat 
messages. Use the no form of this command to set the interval to the default value.

cluster timer interval-in-secs

The interval is 8 seconds.

Global configuration

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.

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.

Interval in seconds between heartbeat messages. The range is 1 to 300 
seconds.

This command was introduced.

Displays the cluster status and a summary of the cluster to which the switch 
belongs.
