Service Ingress QoS Policy Commands
sap-ingress
Syntax
[no] sap-ingress policy-id [create]
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 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 meters combined with classification entries 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. 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 or both as
the match criteria. 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.
NOTE: Before associating a SAP ingress policy with a SAP, resources must be allocated using the CLI
command config> system> resource-profile>ingress-internal-tcam> qos-sap-ingress-resource. Please read
the Service Ingress Qos Policies Chapter above and the 7210 Basic Systems Guide for more information
about this CLI command and resource allocation.
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.
Values
create — Keyword used to create a sap ingress policy.
