Controller AP in the Access Points List in Mobility Express missing?

[donnalbenvillnueva]

I logged into the console of the Controller AP and show version got me this result:

I recently upgraded from 8.3.133 to 8.10.185 but when it finished, the controller AP did not show up as an access point, which was previously shown when I was still in 8.3.133.

@marce1000 

I have attached a log file as requested by @Rich R, there might be useful information about my problem.

@marce1000 

Here's a text file of logs as requested by @Rich R , I hope it contains information to help me with my problem. 

[marce1000]

                      >....Here's a text file of logs as requested by ..
  - Also reboot the AP ; and just after boot connect to it and issue the command show logging ;
                                                                                                                look for anomalies or errors if any

@marce1000 

I have already done that and here's the log file.

[marce1000]

 - We see multiple lines as in :
              >...CDP PoE - waiting for CDP from PSE, timeout ...
   So it could be related to powering : a few things to try
                 1) Enable CDP or LLDP on the switch port (not both)
                 2) Check firmware on switch ,and use latest advisory release , if applicable (in case of bugs)

 M.

[donnalbenvillnueva]

Thing is that, it has been working fine before I upgraded it to 8.10 without any modifications to the switch. Could it be that there are different power requirements for different firmware versions? 

[marce1000]

 - No not different power requirements for different firmware versions (power is a 'sticky AP' requirement); what could happen is that the newer firmware makes improvements to the power negotiation process and that the switch then needs a compatible (more recent) software version too (e.g)

 M.

[Rich R]

It looks like PoE negotiated ok:
Feb 26 05:33:47 brain: CDP PoE negotiation in process, Allocated power 13800 mWa tt Requested power 13800 mWatt
Feb 26 05:33:47 brain: Power mode: Full-Power, power_detection: DC_adapter(FALSE ), 802.3AF_POE(TRUE)
So I don't think that is a problem.

I had such a problem, AP1 was configured as a controller, AP2 disappeared from the Mobility Express GUI, but through the console it was available.

In order for AP2 to appear in the GUI it was necessary to disconnect AP1 from the network, then automatically AP2 appeared in the GUI. After this I connected AP1 after both APs appeared in the Mobility Express GUI.
