Description

 
This module contains a collection of YANG definitions for
supporting the Broadband Forum requirements on the management of
sub-interfaces as applicable to access network equipment. As
such, this module is specific to access network equipment (e.g.,
BBF-specified Access Nodes and FTTdp DPUs).
