Configuring the PPPoE Intermediate Agent
– 654 –
The switch intercepts PPPoE discovery frames from the client and inserts a
unique line identifier using the PPPoE Vendor-Specific tag (0x0105) to
PPPoE Active Discovery Initiation (PADI) and Request (PADR) packets. The
switch then forwards these packets to the PPPoE server. The tag contains
the Line-ID of the customer line over which the discovery packet was
received, entering the switch (or access node) where the intermediate
agent resides.
Outgoing PAD Offer (PADO) and Session-confirmation (PADS) packets sent
from the PPPoE Server include the Circuit-ID tag inserted by the switch, and
should be stripped out of PADO and PADS packets which are to be passed
directly to end-node clients.
Operation Circuit ID – The configured circuit identifier.
Remote ID – String identifying the remote identifier (or interface) on this
switch to which the user is connected. (Range: 1-63 ASCII characters; Default:
Port MAC address)
Operation Remote ID – The configured circuit identifier.
Remote ID Delimiter – Enables a user-specified delimiter for the remote ID.
Delimiter ASCII – A character used to separate components in the remote
circuit ID value. (Range: 0-255; Default: 35, ASCII character “#”)
