WLC9800 Configuration for AP Join Issue

Hello Engineers,

 

I have WLC9800 CL(IOS: 17.3.4) and start to configure with Cisco AP2802 and I am having a AP joining issue.

Here's what I checked:

 

   - Compatibility Matrix : Checked (Compatible)

   - Recognition (sh cdp nei) : Checked (WLC recognize AP as a neighbor)

   - Subnet : AP & WLC is on same subnet 

   - AP CAPWAP Status: Request sent (CAPWAP discovery)

   - WLC Status: Didn't get CAPWAP requests.

 

 

 

From WLC9800 Web GUI, nothing I can see from AP join statistics. 

Did I miss something?

 - Have some extended checks on the 9800 configuration with (CLI/SSH )-command : show tech wireless , have the output processed by https://cway.cisco.com/tools/WirelessAnalyzer/

    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

If it’s in same subnet then WLC discovery can be done over broadcast. Can you share the AP console logs when trying to join and WLC capwap debugs ?

I am assuming WLC is licensed properly and a trust point for Wireless management is configured (show wireless management trustpoint) ? 

-hope this helps-

Console into the AP and post the output to the following commands:

  1. sh version
  2. sh capwap client rcb

Thank you everyone, following your comments, I have checked all of steps (Trustpoint, DHCP option) again

and my AP joined to WLC after I configured wireless management interface.

 

I appreciate your help.

Can your share how to configure wireless management interface?
Thanks.
