I want to implement a Network Access Control ( NAC ) infrastructure in my LAN. My topology is something like:
PC -> ( Untagged Port - PVID 100 - Non 802.1x capable smart switch ) -> ( Hybrid port - 802.1x Dynamic VLAN capable managed switch ) -> PacketFence
So, PCs and other devices aren´t connected directly to the 802.1x Dynamic VLAN capable switch ( HP 1920G ) but to a smart switch ( TP-Link TL-1016DE ). This switch tag frames coming into the untagged port with VLAN ID 100 and send them tagged to the 1920.
My question is: a tagged frame could be subject of 802.1x authentication and dynamic VLAN assigment by the 1920? or that just work for untagged frames?
Thanks in advance
