Hello everyone,
I been working on an issue I have on the wireless Network, the APs are dropping from the WLC and im trying to get some ideas from the logs. I changed the APs from Local to FlexConnect but the result was the same, after certain time the APs start to diassociate from the WLC but I cant find the reason why.
When I check the logs on the WLC I see these:
APF-3-REG_STATE_CHANGE_FAILED: AP SlotId Updation with WLAN data failed for AP: XXX
APF-3-GET_MULTI_ENC_POL_FAILED: Could not Get Multicast Encryption Policy. Unsupported multicast cipher for WPA2.WPA2:0.
When you check the Traps on the WLC you see following output:
4 disassociated previously due to Link Failure. Reason: Capwap Discovery Request.
I Though the problem was a connectivity issue on the switch network but I confirmed that the switches can ping the APs when they disassociate from the WLC. So it seems not to be a connectivity issue.
Do you have any other ideas?
Thank you for your help, have a good day

Which firmware are you running? This might be some bug.

What model of controller?
What model of AP?
What version of software?
What devices are in the network path between AP and WLC?
