I have one 4404 controller running version 5.1.151.
There are 74 AP's which are divided between interface ap-manager 1(on port 1) and ap-manager 2 (on port 2). LAG is disabled.
After a controller reset the AP's wouldn't join port 1 anymore, only port 2. So a maximum of 48 AP's were joined on port 2, while the other 26 AP's kept trying but showed the messages:
Message: 22: AP:001d.e554.f42a: %LWAPP-3-CLIENTERRORLOG: Join Timer: did not recieve join response (controller - xxx-4400)
Message: 23: AP:001d.e554.f42a: %LWAPP-3-CLIENTERRORLOG: Set Transport Address: no more AP manager IP addresses remain
Port 1 and 2 are configured exactly the same way. After I configured an ap-manager interface on port 3 all the remaining AP's joined via that interface.
So the ap-manager interface on port 1 doesn't seem to work. It looks a bit like bug CSCsq30980, but the circumstances are not exactly the same.
Any ideas what's wrong?
I plan to reset the controller again in some time, but for the coming weeks I'll leave it running.
