Netgear M4100-12GF (GSM7212F) - ProSAFE Gigabit L2+ Managed Switch Guía De Administador

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.

In the previous figure, the switch has placed the host in the VLAN (vlan2000) based on the 
user details of the clients. 

The configuration 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

Changing protocol mode will reset ip configuration.
