Cisco recommends that you use the default values, unless your deployment presents a good reason to
change them. Decreasing the values allows increased clustered peer readiness, while increasing the
values allows better performance.

Messages Received (Unicast)
Messages received are the number of cluster synchronization messages received from the clustered

The value should be close to the number of messages sent by the peer. During active use, the values
may not match, but should be close. If traffic stops, the values should become stable and the
messages received will match the messages sent.
