Join error: AIR-AP1852E-H-K9 "Ap model" have a more "9" when join WLC

 Hi All

 

These days,i have met a few similar issue.AIR-AP1852E-H-K9 cannot join WLC(eg,2504\5508).

There are some error when we issue "debug capwap event enable" and "debug capwap error enable" on WLC.

 

As below:

----error info -1

*spamApTask1: Mar 24 15:18:59.752: [PA] Unknown AP type. Using Controller Version!!!

*spamApTask4: Mar 24 15:19:01.708: [PA] 00:38:df:1b:3b:a0 ApModel: AIR-AP1852E-H-K99

*spamApTask6: Mar 24 15:19:02.447: [PA] 00:f8:2c:1b:2b:00 ApModel: AIR-AP1852E-H-K99

*spamApTask7: Mar 24 15:19:04.873: [PA] 00:f8:2c:1b:5b:20 ApModel: AIR-AP1852E-H-K99

......

 

-----error info -2

In addition,there are some APs(AIR-AP1852E-H-K9) which join wlc before can join wlc again normally.

 

WLC software:8.1.131.0 & 8.2.170.0

AP source :RMA or Newly purchased AP

 

I am very serious about this is a serious vulnerability.Do you think?

Is there anybody have occur the issue,and resloved it?

 

Thanks & BR

Hi,
Do you have time/NTP configured correctly on the WLC(s)? Is it happening on multiple WLCs? Can you attach a full output from the debug commands you're running as well as a show sysinfo show inventory show licenses summary show country and show auth-list.

Cheers,
Ric

I have configured the time and it's happening on multiple WLCs.The debug info is always as below:
*spamApTask1: Mar 24 15:18:59.752: [PA] Unknown AP type. Using Controller Version!!!

*spamApTask4: Mar 24 15:19:01.708: [PA] 00:38:df:1b:3b:a0 ApModel: AIR-AP1852E-H-K99

*spamApTask6: Mar 24 15:19:02.447: [PA] 00:f8:2c:1b:2b:00 ApModel: AIR-AP1852E-H-K99

*spamApTask7: Mar 24 15:19:04.873: [PA] 00:f8:2c:1b:5b:20 ApModel: AIR-AP1852E-H-K99

there is not some other useful info.

Hi,

 

Check whether proper country code is enabled on the Controller for associating. Also check for the NTP configuration, Is it proper or Not.

 

Country code China has to be enabled to support these -H- domain access points.

The country code is right,and the time of WLC is also right.

Yes,the AP model is AIR-AP1852E-H-K9,so i have set the country code is CN. And there are some other AP1852E joined before,they can work well at the same time.

I'd recommend migrating away from 8.1.131.0.

Yes,I think so,So i suggested upgrade wlc to 8.3.134.0 ,and waiting for end user update.
I believe there is a bug about the issue.

This, or an error happened in the provisioning process in the factory. I actually suggest to do an RMA.
