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.
