*Mar  1 00:35:55.915: %CAPWAP-5-DHCP_OPTION_43: Controller address 172.16.243.2 obtained through DHCP

Is this the Management IP Address of the WLC?  

 

Make sure that the CAPWAP UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223) are enabled by the firewall?

HI Bernard,

1. First check the date and time on WLC.

2. Paste the DHCP pool config here(specially DHCO option 43 hex string).

 

Regards

Ok, if you say FW has allowed those ports, then console into the AP and ping the WLC Management IP address of 172.16.243.2.  Tell us the result of the ping.

Hi,

1. What is the country code configured on wlc?

 %CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP.

2. AP(172.16.239.151) and WLC(172.16.243.2) are on diff. subnet, did you configured DHCP option 43 or which way AP will find about WLC:

 

-AP is getting ip via DHCP, please also add DHCP option 43 in that pool or try to put in same subnet as WLC.

- or use ip helper command: http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan...

 

Regards
