COMMAND USAGE
◆ The switch inserts a tag identifying itself as a PPPoE Intermediate Agent
residing between the attached client requesting network access and the
ports connected to broadband remote access servers (BRAS). The
switch extracts access-loop information from the client’s PPPoE Active
Discovery Request, and forwards this information to all trusted ports
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 PPP 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.
