Thanks for your reply.
Let me tell you what i meant.
Total of 128 APs and 2 controllers we have. I want to terminate 64 APs on, say, controller 1 and rest of 64 APs on controller 2. Now all i want is that when controller 1 goes down, controller 2 should handle its own 64 APs as well as those which was previously handled by controller 1 (means controller 2 now should be terminating all 128 APs). Same should be true other way around.
Remember these two controllers are placed in the same campus.
So, for this scenario what would be the licensing scheme?
