I recently purchased some 1532 outdoor APs and could not for the life of me figure out how to get them registered with the WLC until I read a post that said I needed to add the AP's MAC address under Security, AAA, AP Policies. Sure enough, this resolved my problem, but I'm now left wondering why I needed to add these APs and not any of the other hundreds of 2702 APs in my environment.
I suppose it's inconsequential, but I'd really like to know why this is required on the 1532 and not the 2702. I understand it has something to do with the AP having a MESH image and being in bridge mode but do not understand this additional requirement. Explanations would be greatly appreciated!
A bridge mode (mesh) AP, must be authorized against AAA, in addition to its MIC or LSC authentication. For more information, see AAA Administration.
