NETWORK ACCESS (MAC ADDRESS AUTHENTICATION)
Network Access authentication controls access to the network by
authenticating the MAC address of each host that attempts to connect to a
switch port. Traffic received from a specific MAC address is forwarded by
the switch only if the source MAC address is successfully authenticated by
a central RADIUS server. While authentication for a MAC address is in
progress, all traffic is blocked until authentication is completed. Once
successfully authenticated, the RADIUS server may optionally assign VLAN
and QoS settings for the switch port.
