Re: [WIRELESS-LAN] Cisco AIR-CAP2702E could not discover WLC

[Bahr, Deb]

THANK YOU everyone for your help.

I added the MAC address to my dhcp server, and then followed Mary's
solution:

Solution from TAC was to ssh to AP:
Debug capwap console cli
Capwap ap controller ip address {IP_of_WLC}

Is now working as should!   Glad we only bought a handful of these.

Cisco AIR-CAP2702E could not discover WLC

[Bahr, Deb]

I am trying to deploy the 2702E AP's with 5508 wireless controllers and am
seeing the following error:

Could not discover WLC.  Either IP address is not assigned or assigned IP
is wrong.  Renewing DHCP IP.  It will receive an IP address, and then
continue this error message and keep trying to renew DHCP IP.

I can connect a AIR-CAP2702I to the same PoE switch and it connects
flawlessly.   I'm not sure why the 2702I will work and not the 2702E.

Has anyone else ran into this issue?
