Added 802.1X Client-based Access Control: Provides client-level security that allows
LAN access to individual 802.1X clients (up to 2 per port), where each client gains access to
the LAN by entering valid user credentials. This operation improves security by opening a
given port only to individually authenticated clients, while simultaneously blocking access
to the same port for clients that cannot be authenticated. See the chapter titled "Configuring
Port-Based and Client-Based Access Control (802.1X)" in the Access Security Guide for your
switch.
