OAM on S-VLAN bidirectional state propagation

The OAM on S-VLAN bidirectional state propagation feature allows monitoring of CFM at the S-VLAN level and propagates the state to associated C-VLANs within the S-VLAN for point-to-point services. This reduces the scale of CFM monitoring by propagating the state from the customer edge (CE) to the provider edge (PE) for a specific S-VLAN.

To enable PE to CE state propagation for an OAM on SVLAN session, configure the interface-status-tlv for the CFM session on the S-VLAN logical interface. This configuration ensures that the PE state is propagated as part of the interface status TLV.

The feature supports propagating SVLAN status on down MEP CFM session using interface-status-tlv for CCC family in PPMAN and CFMMAN modes (inline and non-inline).
