This is often true for devicessuch as network printers, IP phones, and some wireless access points. The switchenables network access from these devices to be controlled by authenticatingdevice MAC addresses with a central RADIUS server.Notes: 1. RADIUS authentication must be activated and configured properly for theMAC Address authentication feature to work properly. (See “RADIUS Client”on page 4-115.)2. MAC authentication cannot be configured on trunk ports.Command Usage• Network Access authentication controls access to the network by authenticatingthe MAC address of each host that attempts to connect to a switch port. Trafficreceived from a specific MAC address is forwarded by the switch only if the sourceMAC address is successfully authenticated by a central RADIUS server. Whileauthentication for a MAC address is in progress, all traffic is blocked untilauthentication is completed. On successful authentication, the RADIUS servermay optionally assign VLAN settings for the switch port.• When enabled on a port interface, the authentication process sends a PasswordAuthentication Protocol (PAP) request to a configured RADIUS server. The username and password are both equal to the MAC address being authenticated. Onthe RADIUS server, PAP username and passwords must be configured in the MACaddress format XX-XX-XX-XX-XX-XX (all in upper case).3-115
