CHAPTER 29
PPPoE
29.1 PPPoE Intermediate Agent Overview
This chapter describes how the OLT 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.
29.1.1 What You Can Do
• Use the PPPoE screen (Section 29.2 on page 254) to display the main PPPoE screen.
• Use the Intermediate Agent screen (Section 29.3 on page 254) to enable the PPPoE Intermediate
Agent on the OLT.
• Use the PPPoE IA Per-Port screen (Section 29.3.1 on page 255) to set the port state and configure
PPPoE intermediate agent sub-options on a per-port basis.
• Use the PPPoE IA for VLAN (Section 29.3.4 on page 261) to enable the PPPoE Intermediate Agent on a
VLAN.
• Use the PPPoE IA for ONT PPPoE Option (Section 29.3.3 on page 259) to configure whether to have the
OLT add PPPoE options for outgoing packets, and forward packets with PPPoE options.
• Use the Option 82 screen (Section 29.3.5 on page 262) to append the Circuit ID and Remote ID to
PPPoE discovery packets of a VLAN.
• Use the Simulation screen (Section 29.3.6 on page 264) to start or stop a PPPoE client test to simulate
the ONT creating a PPPoE session and getting an IP address from the PPPoE server. Up to 1 session can
be simulated at a time.
