We currently have 1 WLC (WiSM) installed in our 6513#1 core switch and will soon be installing a 2nd WLC (WiSM) for redundancy in our 6513#2 core switch. Has anyone been through this setup? Just curious to see advice and and caveats that one may encounter?
That setup will be fine. The only caveats are with what ever code you end up using. 4.1.185 has been the most stable code I have setup on the WiSM's. There are other out here who have implemented the newer 5 code. Just search some of the threads for their opinion.
