 To configure an 802.1X interface:
 - **Required**: Provide the 802.1X RADIUS server IPv4 or IPv6 address. If you want to specify more than one server, provide the priority for each server (a value between 1 and 3). If you specify just one server, Cumulus Linux sets the priority to 1. You can also specify a VRF for outgoing RADIUS accounting and authorization packets. A VRF is optional. 
 - **Required**: Provide the 802.1X RADIUS shared secret.
-- **Required**: Provide either the NAS IP address or the NAS identifier, or both. The NAS IP address is an IPv4 address used only in Access-Request packets from the RADIUS client (the Cumulus switch) to the RADIUS server (not in subsequent packet types, such as Access-Accept, Access-Reject, or Access-Challenge). The NAS identifier is a string such as a fully qualified domain name that identifies the NAS to the RADIUS server. The RADIUS server uses the NAS IP address and the NAS identifier for accounting purposes. On the RADIUS server, the NAS IP address and the NAS identifier identify the source NAS. If two or more NAS devices have the same NAS IP address, you can use a different NAS identifier for each of them to uniquely identify them at the RADIUS server.
