RADIUS session-timeout attribute ignored during MAC auth?

Do Mobility controllers not honor RADIUS session-timeout attributes when successfully authenticated via MAC Auth?

 

First, I authenticate via web auth, and I am returning a RADIUS attribute session-timeout value of 60 seconds. When running the "show user" on my controller, I can see "reauth: 60," and after 60 seconds, my wireless device reauths.

At this point my wireless device tries to reauth using MAC auth. My RADIUS server returns a session-timeout, but instead, you can see the "show user" command lists the value I originally assigned to my employee role on my controller (700 minutes, where it shows "reauth: 42000" below). Why doesn't it show the session-timeout value I set?

Thanks in advance.

Re: RADIUS session-timeout attribute ignored during MAC auth?

I would upgrade to ArubaOS 6.3.x or higher to obtain that option during mac auth:

Re: RADIUS session-timeout attribute ignored during MAC auth?

For whatever reason, I didn't set my MAC Authentication Server Group for my AAA profile - it was set to default. After setting it to my RADIUS server, the attributes are being honored during MAC auth.

 

However, in the list of servers, underneath the option "Fail Through," I did see my server listed. I suppose that list is only active when Fail Through is checked?

 

Thanks!
