Windows 802.1x clients fail when Cisco Switch port is in MAB only mode. RRS feed

  • Question

  • My company has a few different sites in North America. At my site I have implemented 802.1x port security with AD, and MAB for fallback to support Linux clients. This works perfectly at our site, however other sites don't use that configuration.

    My issue is that the other sites are running do1x with MAB as the only option. This is a Cisco house with Cisco switches and Cisco ACS as the radius server. When my 802.1x windows clients go to the other sites, they will not authenticate until we turn off 8021.x on the windows client. I am trying to see if there is a way to force windows to send it's mac if it does not see EAPOL requests. I have looked everywhere and cannot find a solve.

    Thanks in advance.
