Introduction :


Master election is automatic process and IAP's select one of them as Virtual Controller. Certain times, due to this election a far end Instant AP would be selected as master and the traffic flow between merber IAPs and the VC (Virtual Controller) do not get balanced on the wired closet.

Also, when the cluster is mixed with different IAP models, a lower capable AP might become the master leaving others to work as members in the cluster.

In such cases, wlan administrator can enforce a particular Instant AP to act as a Master.
