How Does the Authentication Server Assign DiffServ Policy?
The Dell Networking N-Series switches allow the external 802.1X
Authenticator or RADIUS server to assign DiffServ policies to users that
authenticate to the switch. When a host (supplicant) attempts to connect to
the network through a port, the switch contacts the 802.1X authenticator or
RADIUS server, which then provides information to the switch about which
DiffServ policy to assign the host (supplicant). The application of the policy
is applied to the host after the authentication process has completed. The
Diffserv policy is always applied for the "in" direction of the interface and
applies to the interface as a whole.
