PPPoE Intermediate Agent Configuration
The PPPoE IA function is implemented according to requirements of DSL Forum TR-101 and is
intended for use on switches on the access level.
The function allows PPPoE Discovery packets to be supplemented with the information on access
interface. This is necessary for user interface identification on the access server (BRAS, Broadband Remote
Access Server). PPPoE Active Discovery packets are controlled and intercepted globally for the entire
device and selectively for each individual interface.
Implementation of the PPPoE IA function provides additional control options for protocol messages
by assigning trusted interfaces.
