Chapter 23: Authentication Commands
PPPoE Intermediate Agent
– 811 –
designated by the pppoe intermediate-agent trust command. 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 PPPoE authentication and AAA accounting requests
to a RADIUS server.
•
PPPoE IA must be enabled globally by this command before this feature
can be enabled on an interface using the pppoe intermediate-agent
port-enable command.

server. (Range: 1-48 ASCII characters)

The switch uses the access-node-identifier to generate the circuit-id for
PPPoE discovery stage packets sent to the BRAS, but does not modify
the source or destination MAC address of these PPPoE discovery
packets.
•
These messages are forwarded to all trusted ports designated by the
pppoe intermediate-agent trust command.
