Configuring the PPPoE Intermediate Agent
This section describes how to configure the PPPoE Intermediate Agent (PPPoE IA)
relay parameters required for passing authentication messages 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.
Command Usage
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.
Parameters
These parameters are displayed:
◆ PPPoE IA Global Status – Enables the PPPoE Intermediate Agent globally on
the switch. (Default: Disabled)
Note that PPPoE IA must be enabled globally before it can be enabled on an
interface.
