Service Ingress QoS Policy Commands
sap-ingress
Syntax [no] sap-ingress policy-id
Context config>qos
Description
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 meters that have Forwarding Class (FC), Committed Informa-
tion 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 meters 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 pol-
icy is template. Meters defined in the policy are not instantiated until a policy is applied to a service
SAP.
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. Only one service ingress policy can be provisioned.
The SAP ingress policy with policy-id 1 is a system-defined policy applied to services when no other
policy is explicitly specified. The system SAP ingress policy can be modified but not deleted. The no
sap-ingress command restores the factory default settings when used on policy-id 1. The default SAP
ingress policy defines one meter associated with the best effort (be) forwarding class, with CIR of
zero and PIR of line rate.
Any changes made to the existing policy, using any of the sub-commands are applied immediately to
all services where this policy is applied. For this reason, when many changes are required on a policy,
it is 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 sap-ingress policy-id command deletes the SAP ingress policy. A policy cannot be deleted
until it is removed from all services where it is applied. The system default SAP ingress policy is a
special case; the no command restores the factory defaults to policy-id 1.
Parameters
policy-id — The policy-id uniquely identifies the policy.
