Aironet C1140 - Radio Interface Keeps in Reset State

Hello,

Recently we noticed that one of our C1142 access points has a radio interface (actually is only happening with the one working in BG, so its dot11radio 0) which is entering in reset state and doesn't leave that state. I've seen an older thread about similar (or equal?) issue but was on a different AP model (C1240 if I remember correctly).


The radio interface controller information displays in the end a reset code:


Last radio reset code: 06
Radio resets - total:1 retries:0 failed:0
   Code/Count: 06/00001

Although I was not able to find any information about this reset code in Cisco documents (maybe someone knows where I find it?).

If I try to restart the interface via "shutdown" configuration command it doesn't fix the problem, the workaround that I know of is only by "reload"ing the whole accesspoint.

Of course while in reset state no client can associate to this interface....

Did anyone had similar problem? is there any documented BUG related to this?

Thanks for your time,

Jean-François Mousinho

PS: firmware version is 12.4(21a)JA1.

Re: Aironet C1140 - Radio Interface Keeps in Reset State

If you have Power Injector.

You should put the following command on the AP, configure mode.

"Power inline negotiation injector installed"

By giving a "Show Running" you get something like this

"Power inline negotiation injector 0005.5fa0.cae1"

And the radio to give a "show ip interface brief" will be up.

I hope you serve.

Hi Jose Luciano,

The CDP is off so that command doesn't work.

Can't find anything wrong with your post.

Can you post the "sh logs" when the radios go into "Reset" state?
