802.1X Port Based Network Access Control
This section provides
• a brief description of 802.1X Port Based Network Access Control
• definitions of common terms and abbreviations, and
• an overview of the tasks that may be accomplished using the 802.1X and EAP security and
authentication features.
When using the physical access characteristics of IEEE 802 LAN infrastructures, the 802.1X
standard provides a mechanism for administrators to securely authenticate and grant appropriate
access to end user devices directly attached to switch ports. When configured in conjunction with
NetSight Policy Manager and Radius server(s), Enterasys Networks' switchs can dynamically
administer user based policy that is specifically tailored to the end user's needs.
