The PPPoE server extracts the Line-Id tag from PPPoE discovery stage
messages, and uses the Circuit-Id field of that tag as a NAS-Port-Id
attribute in AAA access and accounting requests.
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 using the pppoe
intermediate-agent vendor-tag strip command.
