Configuring 802.1X
This chapter describes how to configure 802.1X on an HPE 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 "Configuring port security."

802.1X
Access control methods
Hewlett Packard Enterprise 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 that 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 VLAN manipulation
Port-based
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.
MAC-based
If the port is an access, trunk, or 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.
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.

Guest VLAN
Guest VLAN is not supported on ports that perform MAC-based access control.
You can configure a guest VLAN on a port to accommodate users that have not performed 802.1X
authentication, so they can access a limited set of network resources, such as a software server, to
