Configuring Port-Based and Client-Based Access Control (802.1X)
Terminology
N o t e
Port-Based 802.1X can operate concurrently with Web-Authentication or
MAC-Authentication on the same port. However, this is not a commonly used
application and is not generally recommended. For more information, refer
to “Operating Notes” on page 10-57.
Alternative To Using a RADIUS Server
Note that you can also configure 802.1X for authentication through the
switch’s local username and password instead of a RADIUS server, but doing
so increases the administrative burden, decentralizes user credential admin­
istration, and reduces security by limiting authentication to one Operator
password set for all users.
Accounting
The switches covered in this guide also provide RADIUS Network accounting
for 802.1X access. Refer to chapter 6, “RADIUS-Administered CoS and Rate-
Limiting”.
Terminology
802.1X-Aware: Refers to a device that is running either 802.1X authenticator
software or 802.1X client software and is capable of interacting with other
devices on the basis of the IEEE 802.1X standard.
Authorized-Client VLAN: Like the Unauthorized-Client VLAN, this is a
conventional, static VLAN previously configured on the switch by the
System Administrator. The intent in using this VLAN is to provide authen­
ticated clients with network services that are not available on either the
port’s statically configured VLAN memberships or any VLAN member-
ships that may be assigned during the RADIUS authentication process.
While an 802.1X port is a member of this VLAN, the port is untagged. When
a port loses its authenticated client connection, it drops its membership
in this VLAN. Note that with multiple clients on a port, all such clients use
the same untagged, port-based VLAN membership.
Authentication Server: The entity providing an authentication service to
the switch when the switch is configured to operate as an authenticator.
In the case of a switch running 802.1X, this is a RADIUS server (unless
