Cisco Bug: CSCut14540 - MSE HA states are not meaningful enough

8.0(110.0)

Description (partial)

Symptom:
For example ?FAILOVER_ACTIVE? is shown on both MSEs and it means that they failed over to the secondary successfully and is the final state of the failover. However ?FAILBACK_ACTIVE? means that the failback is currently in progress and is not the final state of the failback.
Similarly ?PRIMARY_ACTIVE? and ?SECONDARY_ACTIVE? is extremely confusing for networking engineers which think that boths MSEs are in a active/active state while it should make more sense to have ?PRIMARY_ACTIVE? and ?SECONDARY_STANDBY? and when you failover ?PRIMARY_STANDBY? and ?SECONDARY_ACTIVE?. Another one that confuses everyone is ?TERMINATED? when the primary is up but the active one is the secondary ... terminated implies that it's completely down or dead, not that it's ready to failback ...

Conditions:
normal MSE HA setup
