Service ingress QoS policies

About this task

To create a service ingress policy, perform the following.

Define a policy ID value.
The system does not dynamically assign a value.
Define a description that provides a brief overview of policy features.
Specify a default FC for the policy.

All packets received on an ingress SAP using this ingress QoS policy are classified to the default FC.
Define FC parameters by performing the following.
- Modify the unicast/queue default value to override the default unicast forwarding type queue mapping for fc fc-name.
- Modify the multicast or queue default value to override the default multicast forwarding type queue mapping for fc fc-name.
- Associate a meter for fc fc-name, if required, for both unicast and BUM traffic types.
Specify the following classification criteria - IPv4/IPv6 or MAC criteria or both IP and MAC criteria.

You can define IPv4/IPv6, MAC-based and MAC and IP based SAP ingress policies to select the appropriate ingress meter and corresponding FC for matched traffic.
Create a SAP-ingress policy using a template scope.

The scope can be modified to exclusive for a special one-time use policy. Otherwise, the template scope enables the policy to be applied to multiple SAPs.
Example
The following is a sample service ingress policy configuration output.
