QoS Overview

Meter Parameters

This section describes the meter parameters provisioned on access and network meters
provisioned on access uplinkfor QoS.
The meter parameters are:
•
•
•
•
•
•
•
•
Meter ID
The meter ID is used to uniquely identify the meter. The meter ID is only unique within the
context of the QoS policy within which the meter is defined.
Committed Information Rate
The committed information rate (CIR) for a meter is the long term average rate at which traffic is
considered as conforming traffic or in-profile traffic. The higher the rate, the greater the
throughput user can expect. The user will be able to burst above the CIR and up to PIR for brief
periods of time. The time and profile of the packet is decided based on the burst sizes as explained
in the following sections.
When defining the CIR for a meter, the value specified is the administrative CIR for the meter. The
7210 SAS D, E have a number of native rates in hardware that it uses to determine the operational
CIR for the meter. The user has some control over how the administrative CIR is converted to an
operational CIR should the hardware not support the exact CIR and PIR combination specified.
Refer to the interpretation of the administrative CIR in
The CIR for meter is provisioned on service ingress and network ingress within service ingress
QoS policies and network QoS policies, respectively.
