HI Sudhir,If both WLCs (box

HI Sudhir,

If both WLCs (box to box) are not directly connected then you must enter Client mac address on both the WLCs manually. There is no ther way.


To get Failover between 2 seperate WLC: Check this, it may helps.

Hi Sudhir,In Box to Box

Hi Sudhir,

In Box to Box connection: Controllers have a dedicated HA(Redundency) port, which is used to synchronize configuration between controllers in the Active and Standby states.

The redundancy port is used for configuration, operational data synchronization, and role negotiation between the primary and secondary controllers.

Bulk configuration during boot up and incremental configuration are synched from the Active WLC to the Standby WLC using the Redundant Port.


Hope it helps.
