SSID not broadcasting any more!

  • 1.  SSID not broadcasting any more!

    Posted Feb 10, 2012 12:06 AM

    I have a 4504 controller with 5.0.3.3 code and the SSID has stopped broadcasting all of a sudden! I have a bunch of remote APs on it and they are able to connnect just fine. I've checked the VAP profile and it's enabled as well as the SSID which is also enabled. The AP group is also correctly associated with the VAP profile. I have no idea why it's behaving this way. The only thing I can see that's amiss in the logs is:

     

    Feb 9 14:12:20 :275124:  <ERRS> |fpapps|  XSec Vlan Interface 32 not found line 877

    Feb 9 14:12:20 :275124:  <ERRS> |fpapps|  XSec Vlan Interface 32 not found line 877

     

    Anyone experienced something similar

    Those messages are cosmetic.

     

    Type "show profile errors" or "show ap bss-table" to see what you are working with.

    Looks like you don't have any Virtual APs in ap-groups

    But I do, that's amongst the first things I checked. I re-assigned them the VAP and even re-provisioned the APs but no luck.

    Use the "show ap debug received-config ap-name <name of ap>" command to find out why each AP is doing what it is doing.

    Posted Feb 10, 2012 11:51 AM

    That doesn't show anything:

     

    (Controller) #show ap debug received-config ap-name 00:24:6c:c2:61:bc

    Is that virtual AP enabled?  Type "show audit-trail" to find out what you changed to possibly find out what you did.

    The virtual-AP is indeed enabled. I haven't changed anything in the controller. This just happened when one of the RAP users just reported to me that he wasn't able to see the SSID any more.

    Type "show ap active" and see if the radios are on.  Please also try "show audit-trail" to see if anything has been changed.

    Please check 

    "show rf dot11g-radio-profile default" 

    "show rf dot11a-radio-profile default"

     

    Check the first two parameters 

    Radio enable -- should be "enable"

    Mode  - should say "ap-mode"

    Yup. Check the radio profile.

    D'oh! That was it! How it got disabled by itself I have no idea! But I just enabled the radio profiles and voila!

     

    Man you guys are better than the TAC! Thanks so much to both you guys!
