The cluster timer hello command sets a Hello packet sending interval for the cluster.
The undo cluster timer hello command restores the Hello packet sending interval to the default value.
| Parameter | Description | Value |
|---|---|---|
| time | Specifies a Hello packet sending interval. |
The value is an integer ranging from 1 to 60, in seconds. The default value is 1 second. |
After a cluster is created, master and backup devices in the cluster periodically send Hello packets to each other (backup devices will not send Hello packets to each other). If the master device does not receive Hello packets from a peer within the timeout period, it considers the peer not in the cluster any more.
Hello packet timeout period = Hello packet detection multiplier x Hello packet sending interval
