Configuring RADIUS
About this task
Configure the RADIUS server with the correct VLAN information. Use vendor documentation
to make the required changes.
There are three attributes that the RADIUS server sends back to the NAS (switch) for RADIUS-
assigned VLANs. These attributes are the same for all RADIUS vendors:
• Tunnel-Medium-Type – 802
• Tunnel-Pvt-Group-ID – <VLAN ID>
• Tunnel-Type – Virtual LANs (VLAN)
Configure the switch
The VLAN must be configured correctly on the Avaya Ethernet Routing Switch 4000 Series
device.
