Capturing and logging dot1x traffic

Hi everyone,

I am looking to capture some dot1x traffic. The goal would be to simply log the dot1x under a custom application.

The problem is i dont see a context that I can use for the dot1x traffic (screenshot) under the application signature  to be able to do this.

Is it possible to do some pattern matching that would accomplish the same goal?

Thanks.

Re: Capturing and logging dot1x traffic

Custom application signatures are for tcp/udp traffic. You cannot use them for non-IP layer 3 traffic.

Thank you for the clear answer - that makes perfect sense.

Is there a way to capture dot1x traffic in pattern matching then?

Have you tried adding a pcap filter with non-IP option set to 'include'?

I see the option - but I want the dot1x traffic to be logged on the PA traffic log as perhaps another custom app. I was looking further into it and perhaps the REST API is the answer...?

Is it possible to insert a log entry with REST?

I tried this and yes this does capture the radius traffic going from the WLC <-> Radius. by the way.....

Ok i have been trying to get the data pattern working. Attached is a screenshot of a EAPOL packet.

How would my regex look if i wanted to capture any packet with this source address? (assume the source is 7 bytes).
