Hi, i have 10 access point connected to PoE switch. 9 out of 10 wap are working ok. the 10th ap cannot get conencted to the WLC.

It get IP address, i can see it listed sh cdp neigh at the switch.

the switch is providing power to WAP

Tried to use different switch port with no luck.

Looks like the WAP is using recovery image.


Any ideas would be appreciated.


Thanks

If your WLC is still not yet in production, upgrade to the 6.X IOS.  This version is alot better than the 5.X when it comes to AP looking for the WLC for the first time.


If you are running this version already, console into the AP and in enable mode run the following commands:


1.  clear lwapp private-config;
2.  clear lwapp ap controller ip address
3.  lwapp ap controller ip address

Thanks leolaohoo. I will try suggested steps.

I tried two WAPs already with same results, both APs are brand new, out of the box. Do you think this can be the case that two APs are not behave OK? I put them in different switch port with same results.

Hi,


I was just wondering if you found a solution for the above problem. I'm seeing the same thing.


3750 PoE sees ap with cdp neighbor and gets ip address but it looks like the ap won't get the the full 15.4watts of power and always pulls 14.5watts and never fully boots. Like endpoint mentioned, I have a couple other ap's on same switch that don't have a problem. I've swapped out the ap for another new one and still the same end result.


12.2(55) SE4 code on 3750G-24PS


Thanks,


Craig

what type of AP and what is the recovery code on the it?


Pulling less than 15.4w shouldn't matter until the AP is up and running, and I've seen the 1130/1240 pull 13.4w or so, and still work fine.

Stephen,


Not sure what recovery code is on the 3502i ap as its brand new out of the box and has never been connected to the controller.

Have you tried to swap the ap to the same port as one that is working. I have seen that also when we had bad cabling or a bad patch cord.


Thanks,

Scott,


I didn't try one of the currently working ap ports but I took the originally bad ap(brand new deployment) and a brand new ap into the wiring closet and plugged them directly into the original port and also tried 2 other ports on the same switch and same result.



Thanks,


Craig

I was able to get it running under different WLC. First i statically applied IP address to AP, then i moved to different WLC and for some reason it was working fine after even doug i did not change the actuall switch where this ap was connected to. So, i did not dig further...


thanks guys for all your help..

Hey All,


I have to hang my head in shame to some degree. I consoled into one of the ap's having this issue and noticed that it was failing the to resolve the cisco-capwap-controller dns entry. I entered in the command capwap ap controller ip address X.X.X.X and the ap booted.


The strange thing is that I have multiple ap's in the same address space that have worked flawless with this design.


Will keep an eye on it and note it in the forum if it keeps reocurring.


Thanks


Craig
