Do you have ClearPass?

Hi,

 

It is obsolutely possible to configure both MAC and dot1x together. even possible to configure MAC with internal and dot1x with external radius.

 

the trick is post auth role of MAC authentication, change it to logon role so that it can allow required traffic otherwise if it is a guest role you may issues.

 

in the bellow output you can see that I have enabled both MAC and dot1x auth in the AAA profile and auth trace buff you can see both are success full.

 

 

 

for your Ref :

Re: WPA2 enterprise - Perform MAC authentication before 802.1x

Thank you for your reply.  unfortunately i'm running Aruba instant so i can't use those commands :(

Re: WPA2 enterprise - Perform MAC authentication before 802.1x

this does seem to describe it very well for Instant.

 

http://www.arubanetworks.com/techdocs/InstantMobile/Advanced/Content/MAC%20+%20802.1X%20Authentication.htm

 

[edit] for a second i thought this would allow you to do mac auth only if dot1x fails, a feature that doesn't work on the controller. but looking at "The mac-auth-only role is primarily used for wired clients." i assume it wont work on Instant either for wireless.
