Field Values Additional Information

PPPoE Interfaces

Interface	Name of the PPPoE interface.
	(See the interface naming conventions in the
	J-series Services Router Basic LAN and WAN Access
	Configuration Guide.)

Click the interface name to display PPPoE information for the interface.

State	State of the PPPoE session on the interface.
Session ID	Unique session identifier for the PPPoE session.	To establish a PPPoE session, first the Services
		Router acting as a PPPoE client obtains the Ethernet
		address of the PPPoE server or access concentrator,
		and then the client and the server negotiate a unique
		session ID. This process is refereed as PPPoE active
		discovery and is made up of four steps: initiation,
		offer, request, and session confirmation. The access
		concentrator generates the session ID for session
		confirmation and sends it to the PPPoE client in a
		PPPoE Active Discovery Session-Confirmation (PADS)
		packet.
