AIR-AP1220B Lightweight conversion / WLC support

n-markovic

Hello,

Is AP 1220B (b-only radio) supported for registration to WLC (7.0.x) with Lightweight software? I've managed to convert the AP to Lightweight mode, but I could not get it to register with WLC 2504 (software version 7.0). Is it possible that this AP is only supported if changing the in-built radio module?

In the compatibility matrix (http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html), there is an information that this AP is supported on WLC up to version 7.0.x. On the other hand it is not supported by Autonomous to Lightweight Mode Upgrade Tool (http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html).

Since these APs does not have pre-installed MIC, it is mandatory for them to create Self-Signed Certificate (SSC). Upgrade tool could do this job (along with adding the created SSC hash to the authorized list on WLC), but it does not support this particular AP/radio.

If I do the conversion manually (archive download-sw ...), the AP does not have the SSC needed for communication with WLC. I've tried making the SSC manually (instructions found on this site http://www.skytale.net/blog/archives/37-Manually-converting-a-Cisco-AP-to-LAP-mode.html), while AP is autonomous mode, and then converting it to Lightweight, but the AP still could not register to WLC.

In the debugs (on WLC/AP), I am receiving an error that is described in some Cisco troubleshooting documents as something related to WLC not having an SSC hash in the auth list. Problem is that the AP is not even sending standard CAPWAP messages and there is nothing to be seen in "debug pm pki enable" on WLC...

Thank you!

Take a look at this support doc

I've already seen it.

It did not help. At least with the current issue.

Thanx

You need to provide what is being displayed from the AP console. You have other APs on the WLC correct? If so, then at least we know its configured properly.

Post the outputs to the following commands:

1.  WLC:  sh sysinfo;

2.  AP:  sh version;

3.  AP:  sh inventory

To be honest, I would get a 1142 or a 1252 that is at least 802.11n and be able to use the 2504 without being limited to 7.0.x code.

I agree with you, but the customer wishes to use the old APs. And I am still not sure is it possible. Besides compatibility matrix, other docs are generaly stating that b-only radio is not supported for Upgrade Tool, and I've found this line "

Support for the 802.11b radio is not provided  because it does not support Advanced Encryption Standard (AES)  encryption or Multiple Broadcast System Set Identifier (MBSSID), both of  which are integral to lightweight operation"

on this page http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6306/prod_bulletin0900aecd80321a2c_ps6108_Products_Bulletin.html.

Maybe the 1220B APs are only supported if you replace the radio module...

I will be posting the outputs/debugs soon.

Thanx
