Network Access (MAC Address Authentication)
– 306 –
Command Usage
◆ MAC address 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 quality of service settings for the switch port.
◆ When enabled on a port, the authentication process sends a Password
Authentication Protocol (PAP) request to a configured RADIUS server. The user
name and password are both equal to the MAC address being authenticated.
On the RADIUS server, PAP user name 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.
◆ Configured static MAC addresses are added to the secure address table when
seen on a switch port. Static addresses are treated as authenticated without
sending a request to a RADIUS server.
◆ When port status changes to down, all MAC addresses mapped to that port are
cleared from the secure MAC address table. Static VLAN assignments are not
restored.
◆ 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.
◆ The RADIUS server may optionally return dynamic QoS assignments to be
applied to a switch port for an authenticated user. The “Filter-ID” attribute
(attribute 11) can be configured on the RADIUS server to pass the following
QoS information:
