6.4.2.1.7 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 that 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) and
Maximum Burst Size (MBS) characteristics. The simplest policy defines a single queue that
all ingress traffic flows through. Complex policies have multiple queues that indicate which
queue a packet will flow though.
Policies 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.
It is possible that a service ingress policy will include the dscp map command and the dot1p
map command. 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:
1. 802.1p bits
2. DSCP
The service ingress policy with policy-id 1 is a system-defined policy applied to services when
no other policy is explicitly specified. The system-defined service ingress policy cannot be
modified or deleted.
The no version of this command restores the factory default settings when used on policy-id
1. The default service ingress policy defines one queue associated with the best effort (be)
forwarding class, with CIR of 0 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 service 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.
Parameters policy-id — uniquely identifies the policy. The policy-name cannot be used to create the
policy, but it can be used to reference a policy that already exists.
Values 1 to 65535, or policy-name (up to 64 characters)
