Configuring 802.1X

This chapter describes how to configure 802.1X on an HP device.
You can also configure the port security feature to perform 802.1X. Port security combines and extends
802.1X and MAC authentication. It applies to a network, a WLAN, for example, that requires different
authentication methods for different users on a port. Port security is beyond the scope of this chapter. For
more information about port security, see

HP implementation of 802.1X

Access control methods

HP implements port-based access control as defined in the 802.1X protocol, and extends the protocol to
support MAC-based access control.
Port-based access control—Once an 802.1X user passes authentication on a port, any subsequent
•
user can access the network through the port without authentication. When the authenticated user
logs off, all other users are logged off.
MAC-based access control—Each user is separately authenticated on a port. When a user logs off,
•
no other online users are affected.

Using 802.1X authentication with other features

VLAN assignment
You can configure the authentication server to assign a VLAN for an 802.1X user who has passed
authentication. The way that the network access device handles VLANs on an 802.1X-enabled port
differs by 802.1X access control mode.
Access control
Port-based
MAC-based
With 802.1X authentication, a hybrid port is always assigned to a VLAN as an untagged member. After
the assignment, do not re-configure the port as a tagged member in the VLAN.
"Configuring port
VLAN manipulation
Assigns the VLAN to the port as the port VLAN (PVID). The authenticated 802.1X user
and all subsequent 802.1X users can access the VLAN without authentication.
When the user logs off, the previous PVID restores, and all other online users are
logged off.
•
If the port is a hybrid port with MAC-based VLAN enabled, maps the MAC address
of each user to the VLAN assigned by the authentication server. The PVID of the port
does not change. When a user logs off, the MAC-to-VLAN mapping for the user is
removed.
•
If the port is an access, trunk, or MAC-based VLAN disabled hybrid port, assigns
the first authenticated user's VLAN to the port as the PVID. If a different VLAN is
assigned to a subsequent user, the user cannot pass the authentication. To avoid the
authentication failure of subsequent users, be sure to assign the same VLAN to all
802.1X users on these ports.
