Configuring 802.1x Port Security

In this chapter

Overview of 802.1x port security

The BigIron RX software release 02.2.01 and later supports the IEEE 802.1x standard for
authenticating devices attached to LAN ports. Using 802.1x port security, you can configure a
BigIron RX to grant access to a port based on information supplied by a client to an authentication
server.
When a user logs on to a network that uses 802.1x port security, the BigIron RX grants (or does not
grant) access to network services after the user is authenticated by an authentication server. The
user-based authentication in 802.1x port security provides an alternative to granting network
access based on a user's IP address, MAC address, or subnetwork..

How 802.1x port security works

This section explains the basic concepts behind 802.1x port security, including device roles, how
the devices communicate, and the procedure used for authenticating clients.

Device roles in an 802.1x configuration

The 802.1x standard defines the roles of Client/Supplicant, Authenticator, and Authentication
Server in a network.
