Did you enable the admin status for that ap in the wlc? You have the radios also enabled on the wlc?

Thanks,

Please check the following

1. The AP radio interface is not adminstratively shutdown from inside the AP

2. AP is getting enough power

3. The ADMIN status is up from the WLC

Thanks

The only time I see a WAP's radio won't come up is when it's connected to a power injector and then to a 2950. Can you confirm this is so?

Re: AP showing down status in WLC

vishalpatil86 — Sat, 04 Feb 2012 05:28:07 GMT

no, its not like that...

i connected to 2960, same is happening

Vishal,

Your WLC is in India Domain, which doenst support A radio, while your ap is US domain which support both A radion and b/g Radio

Please paste the "show ip interface brief" also

Is any other AP in your network broadcasting in A domain

Thanks

Last radio reset code: 54 , this is the reason for your radio reset, Please check the below

https://supportforums.cisco.com/thread/2120330

It says the reason as

Status 54: Radio interface was shutdown -- either configured by the user or perhaps part of the boot process.

Thanks

hi,

Interface IP-Address OK? Method Status Prot
ocol
Dot11Radio0 unassigned NO unset up up

Dot11Radio1 unassigned NO unset administratively down down

FastEthernet0 172.16.10.100 YES other up up

yes, there are other APs that are in A domain, but the model number is different 1242AG N-K9

and I am facing problem with 1242AG A-K9

Re: AP showing down status in WLC

nikhilcherian — Sat, 04 Feb 2012 06:12:22 GMT

in the AP do the following steps

ap#debug capwap console cli

ap(config)# int d1

ap(config-if)# no shutdown

Looks like some one has made your interface admin down

Thanks

That is fine, can you do that and check the output of "show ip int brief" again

Re: AP showing down status in WLC

vishalpatil86 — Sat, 04 Feb 2012 06:23:58 GMT

yes, it does work, but when i reload, it again goes down

Re: AP showing down status in WLC

nikhilcherian — Sat, 04 Feb 2012 06:36:13 GMT

Enable the radio, save the config and reload it. And paste the output "more flash:event.log" from AP

Thanks

here it is.....

Re: AP showing down status in WLC

nikhilcherian — Sat, 04 Feb 2012 14:01:07 GMT

The log says

*Feb 4 09:52:11.421: %CAPWAP-5-CHANGED: CAPWAP changed state to JOIN

*Feb 4 09:52:11.583: %CAPWAP-5-CHANGED: CAPWAP changed state to CFG

*Feb 4 09:52:11.688: %CAPWAP-5-CHANGED: CAPWAP changed state to UP

*Feb 4 09:52:11.688: %LINK-5-CHANGED: Interface Dot11Radio1, changed state to administratively down

Which is happening after the AP has joined the WLC, this can primarly becoz the WLC in India domain doesnt support A radio. But it is little surprising that you say there is already an AP with a radio up

Please send the detail of that AP also

Thanks
