Network Access – MAC Address Authentication

Some devices connected to switch ports may not be able to support 802.1X authentication due to hardware or software limitations. This is often true for devices such as network printers, IP phones, and some wireless access points. The switch enables network access from these devices to be controlled by authenticating device MAC addresses with a central RADIUS server.

Note: MAC authentication, web authentication, 802.1X, and port security cannot be configured together on the same port. Only one security mechanism can be applied.

The Network Access feature controls host access to the network by authenticating its MAC address on the connected 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 settings for the switch port

When enabled on a port interface, the authentication process sends a Password Authentication Protocol (PAP) request to a configured RADIUS server. The username and password are both equal to the MAC address being authenticated. On the RADIUS server, PAP username and passwords must be configured in the MAC address format XX-XX-XX-XX-XX-XX (all in upper case).

Authenticated MAC addresses are stored as dynamic entries in the switch secure MAC address table and are removed when the aging time expires. The maximum number of secure MAC addresses supported for the switch system is 1024.

Note: MAC authentication cannot be configured on trunk ports.

The RADIUS server may optionally return a VLAN identifier list to be applied to the switch port. The following attributes need to be configured on the RADIUS server.

•Tunnel-Type = VLAN

•Tunnel-Medium-Type = 802

• Tunnel-Private-Group-ID = 1u,2t [VLAN ID list]

The VLAN identifier list is carried in the RADIUS “Tunnel-Private-Group-ID” attribute. The VLAN list can contain multiple VLAN identifiers in the format “1u,2t,3u” where “u” indicates an untagged VLAN and “t” a tagged VLAN.
