AP Join Issue

I have a client that is adding 18 new AP's to their network.  After getting them configured in the correct vlan, only 5 of them join the WLC (5508).  When I look at the AP join statistics, it shows the following:

RADIUS authorization is pending for the AP

However, under the AP Policies, the 'Authorize MIC APs against auth-list or AAA' option is disabled.  

I am stumped on this one.

TIA for any ideas.  Also, I do not have console access the AP's as the client already had them mounted above the ceiling tiles somewhere.

 

Edit:  Here is the output of show auth-list from the WLC:

 

(Cisco Controller) >show auth-list

Authorize MIC APs against Auth-list or AAA ...... disabled
Authorize LSC APs against Auth-List ............. disabled
APs Allowed to Join
  AP with Manufacturing Installed Certificate.... yes
  AP with Self-Signed Certificate................ no
  AP with Locally Significant Certificate........ no

I do not have console access to any of the AP's that are having the issue, but I know they are all 3602i AP's.

So I figured something else

So I figured something else out.  The 'Base Radio MAC' and 'Ethernet MAC' on the Join AP stats page is the same on the AP's that have not joined and different for the AP's that have joined.  So I looked at the MAC address the switch the AP's are connected to shows and it's different.  I added the different MAC address to the 'Authorized AP' list under the AP Policies page to see what would happen.  Wouldn't you know, the AP joined the WLC.  

Now, this seems odd to me since the 'Authorize MIC AP's against auth-list or AAA' is disabled.  Anyone know why this is happening?  I have a TAC case open as well.

Well, here's the solution.

Well, here's the solution.  These AP's where sent out with the mesh image, so I have to add their MAC address to the Authorized AP list.  I did confirm this with TAC as well.  Learn something new everyday.

Yep... That's ahas the

Yep... That's ahas the problem. Just get them back to local mode

Hi,as you maybe know, an AP

Hi,

as you maybe know, an AP can find the controller in many different ways. My favourite is the DNS one:

- connect the APs to a network with a DHCP server

- create an A record in the DNS server with "cisco-capwap-controller." pointing to your WLC

- ensure that there are no ACLs and routing is ok

When you have done that, APs should be able to find the WLC.

If this is already ok, then we should investigate more. Are the APs new or they have been converted from "Autonomous" to "Lightweight"? If so, you have to do some more configuration on WLC because they could not have a MIC but a SSC, so you will have to add MAC addresses and SSC SHA keys manually. Please refer to this guide an search for SSC (http://goo.gl/EpSz35).

Best regards,

Matteo

All except one of the new AP

All except one of the new AP's is connected to the same switch.  Of the 18 connected to this switch, 5 can join without any issue.  All are fresh out of the box 3602i AP's.

cli/gui discrepancy Authorize

cli/gui discrepancy Authorize MIC APs against auth-list or AAA
CSCuc45044
Symptom:
cli should have "Authorize MIC APs against auth-list or AAA" similar to GUI instead of "Authorize MIC APs against AAA".

Conditions:
when using "Authorize MIC APs against auth-list or AAA" feature cli doesn't descript the same.

Workaround:
none or cosmetic issue

Minor issue.
