Bandwidth management on the egress physical ports (Physical Port 1 and Physical Port 2) is performed at the egress port on the egress IOM instead on the carrier IOM. By default, the forwarding class (FC) information is preserved from network ingress to network egress. However, this can be changed with the QoS configuration applied to the egress SAP of the carrier IOM toward the BB-ISA.
L2TP traffic originated locally in LNS can be marked with the router or service vprn sgt-qos hierarchy.
