Command Line Interface
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. On successful authentication, the RADIUS server may
optionally assign VLAN and QoS settings for the switch port.
