[New Feature - 5.11.0] PPPoE Intermediate Agent

Products ePMP
1

Applicable platforms: AX
Applicable versions: 5.11.0 and above

New 5.11.0 release firmware PPPoE Intermediate Agent feature is introduced for ePMP45XX/ePMP46XX.

When the PPPoE Intermediate Agent feature is enabled, the AP inserts access-loop identification information into PPPoE PADR packets during the PPPoE Discovery phase. This mechanism allows service providers to identify end hosts connected behind an ePMP subscriber device (for example, home routers connected via Ethernet).

The feature is disabled by default.

On the AP, the PPPoE Intermediate Agent provides subscriber line identification by tagging Ethernet frames with Vendor-Specific PPPoE Tags:

  • Circuit ID — includes AP name, frame, slot, port, and VLAN ID information.
  • Remote ID — typically includes the subscriber’s phone number.

Below is a capture of a sample Active Discovery Request (PADR) message illustrating these newly added fields:
