Specifying unicast addresses for failover

and for this to be useful , should the management interfaces sense each others ( be connected at same switch for example ) it is not required to connect them to the same switch.

 

 

also what if i did not put the entry for mgt , will HA work fineyes, it may work even not having mgmt ip in unicast pair but it might not work in some condition too. so, the best practice is to configure it.
