Network Access (MAC Address Authentication)
– 650 –
◆ When port status changes to down, all MAC addresses are cleared from
the secure MAC address table. Static VLAN assignments are not
restored.
◆ The RADIUS server may optionally return a VLAN identifier list. VLAN
identifier list is carried in the “Tunnel-Private-Group-ID” attribute. The
VLAN list can contain multiple VLAN identifiers in the format “1u,2t,”
where “u” indicates untagged VLAN and “t” tagged VLAN. The “Tunnel-
Type” attribute should be set to “VLAN,” and the “Tunnel-Medium-Type”
attribute set to “802.”
