This read-only mib object is used to provide keep alive mechanism when D-LAG status is enabled. Each D-LAG node will have a Max Keep alive count and each D-LAG node maintains seperate keep alive counts for all other remote D-LAG nodes. keep alive count of all remote D-LAG nodes will be incremented every time periodic-sync timer expires but reset to zero for a particular D-LAG node only on receiving periodic-sync/ event-update message from that particular remote D-LAG node. if keep alive count of any of the Remote D-LAG node reaches the max keep alive count, then that Remote D-LAG node will be declared as operationally down/dead. If this object is configured to value '0', then Keep-alive mechanism will be disabled in that D-LAG node.
