3.1.2.5 tSend Timer

The tSend timer helps to maintain the heartbeat of the connection between the failover partners by triggering the sending of CONTACT messages. This timer is initialized when a connection is set up between the failover partners and is reset whenever any DHCP Failover Message is sent to the failover partner. This is a periodic timer with a default value of one minute<7>; that is, unless the timer is stopped, it will expire after every minute. This timer value SHOULD be set appropriately, factoring in the link speed. This timer has to be stopped when the communication between the partners is down.
