[ahmad.syed]

Hi All,

We have 9100 AP trying to join on 9800 WLC. When AP try to join controller it gives below error

Sending Join request to 172.16.31.66 through port 5254

Discarding msg CAPWAP_WTP_EVENT_REQUEST(type 9) in CAPWAP state: Join(5)

Discarding msg CAPWAP_WTP_EVENT_REQUEST(type 9) in CAPWAP state: Join(5).

We have smart license enabled. Having all Country code enable 

Please suggest what could be reason and how to resolve it

Need more information. What exact model and image? AP’s getting up address and are on the same subnet? Typically what helps is a full console output from the ap when being powered up.
