WLC 2504 - Ap join fails with "Unknown AP type. Using Controller Version!!!"

[Bent Eskil Kvisler]

Hi,

I haven't encountered this problem before. On my WLC 2504 I've tried now software versions 8.0.100.0, 7.6.130.0 and 7.4.121.0 (as per recommendation from other supportforum-posts), but still get this debug error when I'm trying to join ap models 1142 and 2602:

Does anyone know what is failing here? Surely the ap's should be "known" in these software versions?

Make sure the time is set properly on the WLC and also make sure the country code for the APs are set on the WLC.

[Bent Eskil Kvisler]

Setting the correct time was it. Embarrassing to overlook this on my part. Thanks for a very quick reply!

[Scott Fella]

No problem, glad to help.

I have the same issue ,  but unfortunately fixing the time did not help.

Unknown AP type. Using Controller Version AIR-AP2802E-E-K9

My WLC is 5508 ,  System info :

Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Product Version.................................. 8.0.135.0

The LAP is getting an IP but not joing the WLC .  I am using the internal DHCP with the management IP interface as DHCP.

Below is the CAPWAP debug output.

Based on the Compatibility Matrix I think you need to upgrade the code on your WLC to support the 2802E. You have also have an E regulatory domain AP which means your AP is designed to be used in one of the countries below. 

E	Algeria	Austria	Bahrain	Belgium	Bosia & Herzegovina	Bulgaria
	Croatia	Czech Republic	Denmark	Estonia	Finland	France
	Germany	Ghana	Gibraltar	Greece	Hungary	Iceland
	Iraq	Ireland	Italy	Jamaica	Kenya	Latvia
	Lebanon	Libya	Lichtenstein	Lithuania	Luxemborg	Malta
	Monaco	Mongolia	Montenegro	Netherlands	Nigeria	Norway
	Oman	poland	Portugal	Romania	Russian Federation	Saudi Arabia
	Serbia	Slovakia	Slovenia	South Africa	Spain	Sri Lanka
	Sweden	Switzerland	Thailand	Tunisia	Turkey	Ukraine
	United Arab Emirates	United Kingdom	Vietnam

I have upgraded the WLC to 8.2.110.0 , but still having the same issue.

Do I need to configure anything on the APs ?

[alois.heilmaier]

Hi, looks like I have the problem also.
WLC-5520 8.2.151.0 With regulatory Domain DE and apModel AIR-AP2802I-E-K9.

Until now I do not know what the problem is. Time is in synch and MIC authorization is enabled.

Unknown AP type. Using Controller Version!!!

any suggestions ?

[Zohaib Khan]

Hi I have the same issue, today i rebooted the controller after that no Access Point is joining the controller.  While debug i can see same logs as given above. I have configured option 43 and 60 as well on cisco switch. Pool commands are:

ip dhcp pool Room-1
 host 192.168.30.113 255.255.255.0
 client-identifier 0188.1dfc.f7cb.30
 default-router 192.168.30.3
 domain-name mina.local
 option 43 hex f108.aca8.1e68
 dns-server 192.168.30.1 4.2.2.2
 option 60 ascii "Cisco AP c3702

I have checked the time and country code all fine but still Access point are not joining. Can you help me out to figure out the issue.

Thanks

[George Stefanick]

What code is your controller on ? 

[Zohaib Khan]

Thanks for response, i am running Software Version 8.0.110.0 on controller

[Scott Fella]

If you just rebooted the WLC and nothing was changed, then that's not normal. All access points were up and running and the code wasn't uograded correct?

-Scott

[Zohaib Khan]

Thanks for response. Yes all the APs  were running and now I am getting this massage. The code was update 20 days ago. Everything was working fine but now I am facing this issue.. what I can do to resolve

[Zohaib Khan]

Hi All,

These settingwork for me:

• from GUI > Security > AP Policies > SSC and MIC certificates are checked
• from GUI > Controller tab > Advanced > Master Controller option is enabled

But i don't got the point, i never use to check this even all other controllers they don't have these settings. Can anyone explain whether it is necessary. I have one more controller in LAN should i change for that as well.
