we use the above wlc and connected its ethernet ports each on a separate lan switch. At the moment only port 2 is connected because of cabling maintenance work.
To assure function of the wlc I mapped the ap manager interface to port 2.
After that I configured a second ap manager interface for future use (when port 1 link will be re-established again) and mapped it to port 1; I used the configuration guide at http://www.cisco.com/en/US/docs/wireless/controller/4.2/configuration/guide/c42mint.html#wp1121574.
To test ap manager 2 interface I exchanged the port mapping with ap manager 1 interface.
After that all APs were disconnected and did not reconnect. Also after a reboot of the wlc no AP reconnected.
So I changed the port mapping back and after that all the APs reconnected again.
So it seems that there is a problem when I map the new created ap manager 2 interface to the active port 2.
Does somebody know a possibility to troubleshoot this scenario?
Are there any cli or debug commands which give more detailed information about the failure? If there is cco documentation concerning this it would be fine if you could send me the url.
Further on, does anybody know where I can see in the gui or via cli which AP is connected to which ap manager interface?
Many thanks in advance,
