Filter policies are supported for ingress and egress of PBB I-SAP in both PBB Epipe and PBB VPLS service.
Only MAC criteria Filter policies is available for use with PBB B-SAPs on ingress with the following functionality:
For PBB B-VPLS B-SAPs, the MAC filter matches the outer MAC header fields (that is, B-DA, B-SA, B-Tag) for traffic received on a B-SAP and forwarded to another B-SAP in the system.
For PBB B-VPLS B-SAPs, the MAC filter matches the inner MAC header fields (that is, the customer MAC DA, SA and VLAN tags) for traffic received on a B-SAP and forwarded out of an I-SAP in the system.
Only MAC criteria filter policies is available for use with PBB B-SAPs on egress. This filter policy only matches the BCB traffic. BEB traffic (that is, PBB originated traffic) cannot be matched using the egress filter policy attached to PBB B-SAP.
