It sets both the forwarding class and the packet’s dot1p, lsp-exp, precedence, or dscp field to the same value.

It groups all packets together into a single aggregate stream, and gives all packets the same treatment.

It copies the three most significant bits in the packet’s dscp field into the forwarding class.

It assigns a forwarding class based on the packet’s dot1p, lsp-exp, precedence, or dscp value.

The EXP bits in the MPLS header.

The egress port scheduler takes the ratio of requested bandwidth to total bandwidth request from all children. It allocates bandwidth fairly, using these percentages and not exceeding the egress interface speed.

The egress port scheduler allocates bandwidth based on a WRR distribution method that takes into account the CIR and PIR requested at each level and the max speed, either default or configured, on egress.

The egress port scheduler allocates bandwidth on a first come, first served distribution method that takes into account the total CIR and PIR requested at each level and the max PIR requested from a single level.

The egress port scheduler will limit the bandwidth offered to the egress port based on the over-subscription factor, provisioned under the router interface, while using a WRR scheduler for the remaining bandwidth.

The egress port scheduler will use the Russian Dolls Method to allocate bandwidth to each level of requested bandwidth. HPO-Only is automatically set to 100%, allowing only high priority traffic to be buffered during congestion.
