Configuring the PPPoE Intermediate Agent
– 618 –
■
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.
◆ Operational 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)
◆ Operational Remote ID – The configured circuit identifier.
