This section provides information to configure network QoS policies using the command line

Topics in this section include:

The ingress component of the policy defines how DiffServ code points (DSCPs) and MPLS

EXP bits are mapped to internal forwarding class and profile state. The forwarding class and

profile state define the Per Hop Behavior (PHB) or the QoS treatment through the router. The

mapping on each network interface defaults to the mappings defined in the default network

QoS policy until an explicit policy is defined for the network interface.

The egress component of the network QoS policy defines the DiffServ oriented queuing

parameters associated with each forwarding class.

Each forwarding class defined within the system automatically creates a queue on each

network interface. This queue gets all the parameters defined within the default network QoS

policy 1 until an explicit policy is defined for the network interface.

If the egressing packet originated on an ingress SAP, or the remarking parameter is defined

for the egress interface, the egress QoS policy also defines the IP DSCP or MPLS EXP bit

marking based on the forwarding class and the profile state.
