Hi, i was tasked with moving two 2100 WLC from one switch to another. Before the move both switches saw 11 APs. supposedly they were configured if one 2100 fails the other takes over. Now i have moved both to a new switch and both are pingable and the config look identical however one of the 2100 controller stopped seeing the APs.
My question is should both WLC see the APs, also the master controller mode box is not checked for any of the WLC. Again both were seeing the APs now only one is. My experience with the 2100 is limited.
thank you. i can confirm this now. thanks for your reply. changing one of the APs to the secondary controller will cause that AP to show up on that controller after a few minutes, so im assuming if controller 1 ever goes down they will automatically move to controller 2.
actually i just only the order of the primary/secondary controller on one of the APs and that AP is now showing up on the controller that had no APs. So im assuming what im seeing is normal that only the primary will list the APs and the secondary only lists the APs when the primary if offline?
I wonder why both controller were listing the APs before, i wonder if they were not aware of each other before.
