LTM network failover

From the manual I got that LTM can use network to determine if the active unit is working fine if network failover is enabled. And for synchronization it is recommended that a separate segment is used...

Yes, the standby unit will listen for status message from the active unit on TCP 1028. The peer IP address is the source it will expect to hear this from. If status message is not received within the time limit, it will make itself the active unit. This is why it is important to have a reliable network connection for Network Failover transport, otherwise, you will have "unwanted" active-active on your hand. See Sol2397 for information on Network Failover, as well as Serial Failover.
