1142 AP not joining Virtual WLC

marc.groenen
Level 1
Level 1

‎09-09-2016 01:36 AM - edited ‎07-05-2021 05:48 AM

So im running a virtual WLC with v8.2.121.0 and am currently testing if AP's can join.

Since:

http://www.cisco.com/c/en/us/support/docs/wireless/virtual-wireless-controller/113677-virtual-wlan-dg-00.html

i upgraded the AP to c1140-k9w8-tar.153-3.JD.tar so he should be able to join.

Still the AP cannot join the vWLC.

In the debugging i can only see the following:

*Sep 9 11:28:31.514: %CAPWAP-5-SENDJOIN: sending Join Request to 10.1.4.10

So after the join request it stays silent on the AP for about 60 seconds.

Since the WLC receive the message there is probably something going wrong from the WLC to the AP.

Going to check the virtual environment :S and possible a firewall i guess...

AP policies are default.

Also checked if the MIC certificate had expired but that isnt the case.

The test AP can join a normal 5508 WLC running v8.x without any problem.

Currently doing some more tests in my test ESX environment and cant seem to get it to work there either.

Created Data and Service port adapter and enabled promiscous mode + all VLAN's.

Also trying the v7.4.150.0 Cisco advised version but need to get an eval license

Run "debug capwap errors enable" on the WLC and provide output

What is the WLC IP address, 10.17.4.10, 10.1.4.11 or 10.17.4.10. And what is AP's IP 10.16.14.51 or 10.10.14.51.

mustehsan thank you for youre commitment.

I filtered the customer IP space appearantly i didnt use the same values my apoligizes.

I just solved the issue appearantly you need to activiate the license on the vWLC although it says it supports 200/3000 AP's.

So after activating the already active license and accepting the EULA the AP's could join.

Strange i didnt get anything in the debugging about the licenses not being active.
