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.
