Appendix C: Security Settings On Wireless Clients And RADIUS Server Setup
Configuring A RADIUS Server
Selection of the VLAN is usually based on the identity of the user. The RADIUS 
server informs the NAS (for example the access point) of the selected VLAN as part 
of the authentication. This setup enables users of Dynamic VLANs to move from 
one location to another without intervention and without having to make any 
changes to the switches.
In the case of the 9160 G2 Wireless Gateway, if the user has selected to use an exter-
nal RADIUS server (configured on the Security page), then an External RADIUS 
server will try to authenticate the user. A user’s authentication credentials are passed 
to a RADIUS server. If these credentials are found to be valid, the NAS configures 
the port to the VLAN indicated by the RADIUS authentication server.
C.11.1  Configuring A RADIUS Server
A RADIUS server needs to be configured to use Tunnel attributes in Access-Accept 
messages, in order to inform the access point about the selected VLAN. These 
attributes are defined in RFC 2868 and their use for dynamic VLAN is specified in 
RFC 3580.
In the case of FreeRADIUS server, the following options may be set in the users file 
to add the necessary attributes.
example-userAuth-Type :=EAP, User-Password =="password"
Tunnel-Type = 13,
Tunnel-Medium-Type = 6,
Tunnel-Private-Group-ID = 7
Tunnel-Type and Tunnel-Medium-Type use the same values for all stations. Tunnel-
Private-Group-ID is the selected VLAN ID, however it can be different for 
each user.
