Service Ingress QoS Policy Commands

[no] sap-ingress {policy-id | policy-name}

This command is used to create or edit the ingress policy. The ingress policy defines the Service Level

Agreement (SLA) enforcement service packets receive as they ingress a SAP. SLA enforcement is

accomplished through the definition of queues that have Forwarding Class (FC), Committed

Information Rate (CIR), Peak Information Rate (PIR), Committed Burst Size (CBS), and Maximum

Burst Size (MBS) characteristics. The simplest policy defines a single queue that all ingress traffic

flows through. Complex policies have multiple queues combined with specific IP or MAC match

criteria that indicate which queue a packet will flow though.

Policies in effect are templates that can be applied to multiple services as long as the scope of the policy

is template. Queues defined in the policy are not instantiated until a policy is applied to a service SAP.

A SAP ingress policy is considered incomplete if it does not include definition of at least one queue

and does not specify the default action. The OS does not allow incomplete SAP ingress policies to be

applied to services.

SAP ingress policies can be defined with either IP headers as the match criteria or MAC headers as the

match criteria. The IP and MAC criteria are mutually exclusive and cannot be part of the same SAP

ingress policy.

It is possible that a SAP ingress policy will include the dscp map command, the dot1p map command

and an IP or MAC match criteria. When multiple matches occur for the traffic, the order of precedence

will be used to arrive at the final action. The order of precedence is as follows:

not specified, an error will occur if the destination policy ID exists.
