Hi Marlon,

i think you do not need to take care about bandwith usage based on Authentication and Assessment on a client port.

802.1x exchange a few EAPoL Pakets for PEAP or EAP-TLS. Assessment exchange some SSL based TCP Traffic from Assessment Agent to NAC Gateway and vice versa.

This is not nothing compare to the login traffic of the client.

Hi Marlon, agreed with Matthias.
The agent based solution is a host based software agent which resides on the connecting End-System. The agent will report back to the server(NAC) the current level of compliance of the end-system.
