PPPoE Intermediate Agent
– 859 –
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.
â—† 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.
EXAMPLE
Console(config)#pppoe intermediate-agent

This command sets the access node identifier and generic error message
for the switch. Use the no form to restore the default settings.
