9800 CL - Two APs Same Configuration Only One Allowing Client Connect

chtucci

Level 1

With the error:  

Client state transition: S_CO_DELETE_IN_PROGRESS WLC9800

{wncd_x_R0-6}{1}: [client-orch-state] [25366]: (note): MAC: 0030.4449.8a24 Client state transition: S_CO_DELETE_IN_PROGRESS -> S_CO_DELETED

I don't understand why clients are connecting fine on one ap but not the other?

 - You can debug/monitor  client  behavior on the particular AP with :
                    show  ap client-trace events mac <CLIENT MAC>
       (this command must be executed on the involved access point); use these tools too for client debugging : https://logadvisor.cisco.com/logadvisor/wireless/9800/9800ClientConnectivity

     Last but not least have a checkup of the 9800 CL configuration with the CLI command show tech wireless , have the output analyzed by https://cway.cisco.com/wireless-config-analyzer/

Have you checked if APs have same configuration and not wrongly spelled Tags on the unable-to-receive-connections one?

Most importantly:

The WLC is 9800 on 17.03.06.  The APs are 9120 AXE-B.  The configuration between the two is the same.  The client trying to reach these APs are Cradlepoints that present a certificate.  They connect to only one ap, and when that ap is admin down, they won't connect with the other AP.

 

   @chtucci  Have you already executed the tasks mentioned in my first reply ?

Calling for them to test today, and I'll try then.  

I tried using the config analyzer but no output occurred.  I posted some more details to the main thread about testing though.

  - Please note :  use CLI show tech wireless , for WirelessAnalyzer , not simple show tech

Yessir, I sure did.  Used that full command.  It does dump a tremendous number of lines though.

 

                >..It does dump a tremendous number of lines though.
  - How do you mean , can you post a  (beginning) part of this output e.g. ?

 - You need to save the output of show tech wireless to a file , usually best is to activate a operator logging option such as with  PuTTy when connecting to the controller , then you have the output automatically , then you edit the file after the session is finished so that only the output starts with the correct beginning of 'show tech wireless' and also additional stuff at the  end from terminating the connection is removed , then you feed the obtained and feed  output to :  https://cway.cisco.com/wireless-config-analyzer  , meaning upload the file and or drag it into the upload field that you see on the screen ,
