Network QoS Policy Command Reference
104 Quality of Service Guide
The egress component of the network QoS policy defines the queuing parameters associated with each
forwarding class. Each of the forwarding classes 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 interfaceaccess uplink port. 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.
Network policy-id 1 exists as the default policy that is applied to all network interfaces by default. The
network policy-id 1 cannot be modified or deleted. It defines the default DSCP-to-FC mapping and
MPLS EXP-to-FC mapping and for the ingress. For the egress, it defines six forwarding classes which
represent individual queues and the packet marking criteria.
Network policy-id 1 exists as the default policy that is applied to all network ports by default. This
default policy cannot be modified or deleted. It defined the default DSCP-to-FC mapping and default
unicast meters for ingress IP traffic. For the egress, if defines the forwarding class to Dot1p and DSCP
values and the packet marking criteria.
If a new network policy is created (for instance, policy-id 3), only the default action and egress
forwarding class parameters are identical to the default policy. A new network policy does not contain
the default DSCP-to-FC and MPLS-EXP-to-FC mapping for network QoS policy of type ip-interface
or the DSCP-to-FC mapping (for network QoS policy of type port). The default network policy can
be copied (use the copy command) to create a new network policy that includes the default ingress
DSCP-to-FC and MPLS EXP-to-FC mapping (as appropriate). You can modify parameters or use the
no modifier to remove an object from the configuration.
Any changes made to an existing policy, using any of the sub-commands, will be applied immediately
to all network interfaces where this policy is applied. For this reason, when many changes are required
on a policy, it is highly recommended that the policy be copied to a work area policy-id. That work-
in-progress policy can be modified until complete and then written over the original policy-id. Use the
config qos copy command to maintain policies in this manner.
The no form of this command deletes the network policy. A policy cannot be deleted until it is removed
from all entities where it is applied. The default network policy policy-id 1 cannot be deleted.
