This command creates or edits a QoS network policy. The network policy defines the treatment
Description
packets receive as they ingress and egress the network port.
The QoS network policy consists of an ingress and egress component. The ingress component of
the policy defines how LSP 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 7210 SAS. 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. It also
defines the rate-limiting parameters for the traffic mapped to each forwarding classes. Traffic
mapped to each forwarding class can be rate limited using separate meters for each uni-cast and
multipoint traffic.
The egress component of the network QoS policy defines forwarding class and profile state to LSP
EXP values for traffic to be transmitted into the core network. If the egressing packet originated on
an ingress SAP, the parameter is always enabled for the networkport, the egress QoS policy also
defines the Dot1p bit marking based on the forwarding class and the profile state.
Network policy-id 2 exists as the default policy that is applied to all IP interface by default. The network
policy-id 2 cannot be modified or deleted. It defines the default LSP EXP-to-FC mapping and default meters
for unicast and multipoint meters for the ingress MPLS packets. For the egress, it defines eight forwarding
classes which defines LSP EXP values 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, default
meters for unicast and multipoint traffic and egress forwarding class parameters are identical to the
default policy. A new network policy does not contain the default LSP EXP-to-FC mapping for
network QoS policyof type ip-interface or the DSCP-to-FC mapping (for network QoSpolicy 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 LSP EXP or DSCP to FC mapping (as
appropriate). You can modify parameters or use the no modifier to remove an object from the
configuration.
