PPPoE Intermediate Agent Overview

This chapter describes how the Switch gives a PPPoE termination server additional information that
the server can use to identify and authenticate a PPPoE client.
A PPPoE Intermediate Agent (PPPoE IA) is deployed between a PPPoE server and PPPoE clients. It
helps the PPPoE server identify and authenticate clients by adding subscriber line specific
information to PPPoE discovery packets from clients on a per-port or per-port-per-VLAN basis
before forwarding them to the PPPoE server.
