How Does the Authentication Server Assign DiffServ Filters?
The PowerConnect M6220, M6348, M8024, and M8024-k 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.
For additional guidelines about using an authentication server to assign
DiffServ policies, see "Configuring Authentication Server DiffServ Filter
Assignments" on page 514.
What is the Internal Authentication Server?
The Internal Authentication Server (IAS) is a dedicated database for localized
authentication of users for network access through 802.1X. In this database,
the switch maintains a list of username and password combinations to use for
802.1X authentication. You can manually create entries in the database, or
you can upload the IAS information to the switch.
If the authentication method for 802.1X is IAS, the switch uses the locally
stored list of username and passwords to provide port-based authentication to
users instead of using an external authentication server. Authentication using
the IAS supports the EAP-MD5 method only.
