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.
