Anyone else having problems with other people's Cisco access points logging on the wrong controller?
I was talking to a customer of mine (who provides services to cable companies) who has that happen regularly, and I suspect that it's an issue related to Cisco's discovery.
Once they appear on someone else's controller, then you of course have the option of doing whatever you want to them. :)
If you bring up small groups of APs do a manual prime. Also, if the "other" controllers are using OTP that could be an issue. I had that happen before where we had to independent cisco lwapp systems. New aps would always join the other system. It wanst till we turned off over the are provisioning of the other system that it stopped.
