Netlogin MAC auth not triggering RADIUS

Netlogin MAC auth not triggering RADIUS

Anonymous
Not applicable
Hi,

Believe this was working at some point but can't workout where the issue is, but in summary when an end-system is connected to a MAC auth enabled port (22 in this case) its not triggering the RADIUS exchange. This is showing up in the RADIUS counters on the switch remaining 0, and a TCPDUMP on the RADIUS server (NAC) are showing nothing hitting it?

Everything seems to be enabled and configured correctly from what I can tell, no messages are showing in the switch logs, and the switch has been rebooted?

Here is the config:

Hi
What kind of end system did you connect? I had these problem, just end system didn't generate any traffic.
