RADIUS Attributes for 802.1 Support
Dell Networking systems include the following RADIUS attributes in all 802.1X-triggered Access-Request messages:
Attribute 5 NAS-Port: the physical port number by which the authenticator is connected to the supplicant.
Attribute 31 Calling-station-id: relays the supplicant MAC address to the authentication server.
Attribute 41 NAS-Port-Type: NAS-port physical port type. 5 indicates Ethernet.
Attribute 81 Tunnel-Private-Group-ID: associate a tunneled session with a particular group of users.
Configuring 802.1X
Configuring 802.1X on a port is a two-step process.
1. Enable 802.1X globally (refer to Enabling 802.1X).
2. Enable 802.1X on an interface (refer to Enabling 802.1X).
