Supported on all 7210 SAS platforms as described in this document
This command creates or edits a QoS network policy. The network policy defines the treatment packets receive as they ingress and egress the access uplink port and network IP interface in network mode of operation.
The QoS network policy consists of an ingress and egress component. The ingress component of the policy defines how dot1p bits are mapped to the internal FC and profile state. The FC 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 FC. Traffic mapped to each FC can be rate limited using separate meters for unicast and multipoint traffic.
The egress component of the network QoS policy defines the FC and profile to packet header priority bits (for example: dot1p bits).
The network policy 1 cannot be modified or deleted. It defines the default dot1p to FC mapping and default meters for unicast traffic and optional multipoint meters for BUM traffic on the, ingress. For the egress, it defines eight FCs which represent individual queues and the packet marking behavior.
If a new network policy is created (for instance, policy 2), only the default action and egress FC parameters are identical to the default policy. A new network policy does not contain the default dot1p to FC mapping for network QoS policy. The default network policy can be copied (use the copy command) to create a new network policy that includes the default ingress dot1p to FC mapping (as appropriate). You can modify parameters or use the no modifier to remove an object from the configuration.
Changes made to an existing policy, using any of the sub-commands, are applied immediately to all access uplink ports where this policy is applied. For this reason, when many changes are required on a policy, Nokia highly recommends that the policy be copied to a work area. 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 1 cannot be deleted.
