the results of the metering/policing for the corresponding customer UNI.
1. The SAP on PE1 may use the DE bit from the customer STAG to classify the frames as
2. When the packet leaves PE1 via SDP, the DE indication must be copied onto the
3. As the packet arrives at PE2, ingress into the related SDP, the DE indication is used to
4. Egress from the PE2 SAP, the internal PHB may be used to perform marking of the DE
A combination of two access networks can be possible. If PBB encapsulation is used, the
configuration used for DE in SAP and SDP policies applies to both BVID and ITAG DE bits.
When both fields are used the BVID takes precedence.
