Cisco 350AP and 802.1x EAP

Apr 03, 2006 6 Replies

We are currently using stack WEP, and I would like to start using



802.1x with dynamic rotating WEP keys. We are out of maintenance, and we are running 12.02T1 of the VxWorks based OS.

I am having trouble getting this to work. I know my Radius server and supplicants are good, because we use the same supplicants and Radius server for our newer wireless system without any problems. I am trying to figure out the right set of configuration options, and I can not get pass the following warning message when a client tries to associate: Station xx:xx:xx:xx:xx Failed Authentication, status "Unsupported Authentication Algorithm".



If someone could please guide me in the right direction, I would really appreciate it. Thx.

First I would suggest upgrading to 12.04 or 12.05 of VxWorks Firmware.

Try "require EAP" under the "open Authentication" in addition to "Network-EAP".

Network EAP is only for LEAP with Cisco client adapters. Many third party adapter do "open authentication with EAP".

The APs are no longer under mainteance, so I can not upgrade.

'Accept Authentication type:' and 'Require EAP:' are both set to open. I have set the broadcast keys to rotate every 30 minutes.

Do I put anything in the key field for WEP key 1 or do I leave it blank?

I am getting closer. I know get messages on the main page that: Station=xx:xx:xx:xx:xx user="domain\\userid" Failed EAP-Authentication

My Radius server is reporting an incorrect login fro the userid.

I can use this very same laptop and userid to authenticate to our current wireless system, so I am suspecting it is something still with the 350 configuration. Any ideas?

The final VxWorks firmware was released as a free download in Oct 2004. There is an IOS Conversion Image for the AIR350 APs.

When broadcast key rotation is enabled, you'll don't need to set any WEP key manually- but set encryption to required.

What EAP type, what supplicant, what WLAN card?

I upgraded the AP to 12.05 this afternoon. Thanks for the information on that.

A WEP key was previous entered in the field. The field is blank for key 1, and I am not sure how I can zero it out or reset it.

We are using EAP-PEAP and I am using the Windows XP SP2 supplicant. My WLAN card is a Dell Trumobile 1300. I am running the most current Truemobile driver from Dell's website.

You have been very helpful. Thx.

End game. Thanks for everyone's help. This is now working. I was running into a bizarre issue with our Nortel load balancer that was performing a round-robin load balance metric between the load balanced radius servers. This was breaking the authentication. I changed the metric on the load balancer to host affinity and everything is working like a champ.
