Configuring Dynamic Vlan Assignment With Port Authentication - Dell S4048–ON Configuration Manual

Configuring Dynamic VLAN Assignment with Port
Authentication
Dell Networking OS supports dynamic VLAN assignment when using 802.1X.
The basis for VLAN assignment is RADIUS attribute 81, Tunnel-Private-Group-ID. Dynamic VLAN assignment uses the standard dot1x
procedure:
1 The host sends a dot1x packet to the Dell Networking system
2 The system forwards a RADIUS REQEST packet containing the host MAC address and ingress port number
3 The RADIUS server authenticates the request and returns a RADIUS ACCEPT message with the VLAN assignment using Tunnel-
Private-Group-ID
The illustration shows the configuration on the Dell Networking system before connecting the end user device in black and blue text, and
after connecting the device in red text. The blue text corresponds to the preceding numbered steps on dynamic VLAN assignment with
802.1X.
