Overview

The ingress component of the policy defines how 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 defaults to the mappings defined in the default
network QoS policy until an explicit policy is defined for the .
The egress component of the network QoS policy defines the associated with each forwarding
class.
Network policy-id exists as the default policy .The network policy-id cannot be modified or
deleted. It defines the default mapping and for the ingress. For the egress, it defines forwarding
classes which and the packet marking criteria.
New (non-default) network policy parameters can be modified. The no form of the command
reverts the object to the default values.
Changes made to a policy are applied immediately to all where the policy is applied. For this
reason, when a policy requires several changes, it is recommended that you copy the policy to a
work area policy-id. The work-in-progress copy can be modified until all the changes are made
and then the original policy-id can be overwritten with the config qos copy command.
For information about the tasks and commands necessary to access the command line interface
and to configure and maintain your router devices, refer to CLI Usage chapter in the Basic System
Configuration Guide.
