• After a port is in an authorized state, if any client initiates dot1x authentication, the port
clears authenticated clients’ states, and in the process clears the VLAN assigned to the
port (if any). Then the port continues with the new client authentication and authorization
process.
• When a client authenticates itself initially on the network, the switch acts as the
authenticator to the clients on the network and forwards the authentication request to the
RADIUS server in the network.
For use in VLAN assignment, the following tunnel attributes are used:
• Tunnel-Type = VLAN (13)
• Tunnel-Medium-Type = 802
• Tunnel-Private-Group-ID = VLANID where VLANID is 12 bits, with a value between 1 and
4094.

Figure 31. VLAN assignment using RADIUS
In the previous figure, the switch has placed the host in the VLAN (vlan2000) based on the
user details of the clients.
The configureation on a RADIUS server for a user logged in as admin is:
• Tunnel-Type = VLAN (13)
• Tunnel-Medium-Type = 802
• Tunnel-Private-Group-ID = 2000
