Switching

Is it possible to enable dot1x on EX series without Supplicant software on PC. I have configured dot1x in conjunction with MAG2600 and dynamic VLAN mapping but have don't have the MAG in this case just the EX series and PC. I can use probably the free radius but how will this work on PC without any supplicant. How can I restrict access to ports unless authenticated by some means. Is this do able?

Just search the web!  The below should do it:

This url talks about bypassing coupel of MAC address ( especially printers etc) I have 300+ AD users and looking to enable dot1x with the supplicant ( like Junos pulse). Again is it possible to enable dot1x with free radius and AD integration? My understanding is you still need somekind of supplicant.

Once again, the web has all:

http://www.juniper.net/documentation/en_US/junos13.2/topics/example/authentication-mac-radius-ex-series.html

If no supplicant, that all 300+ devices are non-dot1x capable.  Radius and AD, not that I am aware.  Radius and MAC yes, or else use built-in OS 802.1x supplicant, and try searching the web for answers.

I figured out the plan.

Use Windows embedded dot1x as supplicant along with Radius for Switch authentication. Below is a link for turning 8021x for Window machines.
