the NAS-Port-Id value is the same for all subscribers on the Ethernet link. Enabling the
router to capture the remote circuit ID sent from the DSLAM and use it as a RADIUS or
L2TP attribute facilitates the process of identifying individual subscribers on an Ethernet
link.

PPPoE Remote Circuit ID Capture

When you enable capture of the PPPoE remote circuit ID by issuing the pppoe
remote-circuit-id command, the E Series router captures the remote circuit ID value if it
is sent from the DSLAM. The PPPoE intermediate agent on the DSLAM appends a
vendor-specific tag containing the remote circuit ID to the existing PPPoE PADI or PADR
packet and sends this packet to the E Series router. The PPPoE remote circuit ID value
can be a maximum of 64 characters. The router stores this value on the line module on
which the PPPoE interface is configured.

PPPoE Remote Circuit ID Format

By default, the router formats the captured PPPoE remote circuit ID to include only the
agent-circuit-id suboption (suboption 1) of the PPPoE intermediate agent tags sent from
the DSLAM. To configure a nondefault format for the captured PPPoE remote circuit ID,
you can use one of the radius remote-circuit-id-format commands listed in Table 20
on page 376.
Table 20: Configuring Nondefault Formats for the PPPoE Remote Circuit
ID
To Configure This Nondefault Format
Include only the agent-remote-id suboption
(suboption 2) of the tags supplied by the PPPoE
intermediate agent
Include both the agent-circuit-id suboption
(suboption 1) and the agent-remote-id
suboption (suboption 2) of the tags supplied
by the PPPoE intermediate agent
Include the NAS-Identifier [32] RADIUS attribute
with either or both of the agent-circuit-id and
agent-remote-id suboptions of the tags
supplied by the PPPoE intermediate agent
Use This Command
