Hi Cisco NetPro,
I have a client (a University) that is using the WLC 4402 with software 4.2.176. They have a residence area for students that is serviced by the local cable provider for Internet. Additionally, the University wants to provide wireless access to those students who are unwilling to pay for cable Internet service - but are willing to accept the limited bandwidth (and various protocol restrictions) of the University Internet.
Our challenge is that is we anticipate those students with cable Internet to setup their own wireless APs. Naturally we're concerned with channel overlap between these autonomous (and not controlled by the University) APs and the University wireless system. We could ban student controlled APs, but it seems a bit restrictive so I'm hoping we can come to some sort of a solution.
I was thinking that if we cede channel 6 to student APs, and use channels 1 and 11 for the University wireless we can keep everyone happy. I know we can do this globally, but we have a bunch of other non-residence APs and I'd rather continue to use channel 6 elsewhere in the network. I know we can set the channel manually on a per-AP basis, but then these APs can't react and hop to the other channel if some interference does appear on channels 1 or 11.
The perfect solution would be to specify a DCA for the residences, and a DCA for the rest of the network but I can't see a way to do this. Is there a way?
