IP Service > PPPoE Intermediate Agent

PPPoE Intermediate Agent (PPPoE IA) relay parameters control the way authentication messages are passed between a client and broadband remote access servers.

Configuring PPPoE IA Global Settings

Use the IP Service > PPPoE Intermediate Agent (Configure Global) page to enable the PPPoE IA on the switch, set the access node identifier, and set the generic error message.

When PPPoE IA is enabled, the switch inserts a tag identifying itself as a PPPoE IA residing between the attached client requesting network access and the ports connected to broadband remote access servers (BRAS). The switch extracts access-loop information from the client's PPPoE Active Discovery Request, and forwards this information to all trusted ports (designated on the Configure Interface page). The BRAS detects the presence of the subscriber's circuit-ID tag inserted by the switch during the PPPoE discovery phase, and sends this tag as a NAS-port-ID attribute in PPP authentication and AAA accounting requests to a RADIUS server.

Configuring PPPoE IA Interface Settings

Use the IP Service > PPPoE Intermediate Agent (Configure Interface) page to enable PPPoE IA on an interface, set trust status, enable vendor tag stripping, and set the circuit ID and remote ID.
