qos cir (PW template view)

Function

The qos cir command configures QoS parameters in a PW template.

The undo qos command deletes QoS parameter settings from a PW template.

By default, QoS parameters are not configured in a PW template.

Format

qos cir cir-value [ pir pir-value ] [ qos-profile qos-profile-name ]

undo qos

undo qos cir cir-value [ pir pir-value ] [ qos-profile qos-profile-name ]

Parameters

Parameter	Description	Value
pir pir-value	Specifies the Peak Information Rate (PIR). PIR: refers to the maximum number of packets that can be processed per second as well as the maximum bandwidth required to process packets.	The value is 0 or an integer ranging from 16 to 4294967294, in kbit/s. If you do not specify pir pir-value, the pir-value value is equal to the cir-value value. If you want to specify pir pir-value, ensure that the pir-value value is greater than or equal to the cir-value value. pir-value and cir-value cannot be both 0s. If the cir-value value is 0, you must specify pir-value.
qos-profile qos-profile-name	Specifies the name of the referenced QoS profile.	The value is a string of 1 to 63 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed with double quotation marks (").
cir cir-value	Specifies the Committed Information Rate (CIR). The CIR is the relatively minimum bandwidth. When the CIR is set, the following action is taken on packets: Forward: forwards the packets whose traffic rate is lower than the CIR. Discard: discards the packets whose traffic rate is higher than the PIR. Re-mark: re-marks the packets whose traffic rate is between the CIR and PIR and allows these packets to be forwarded using the best effort model.	The value is 0 or an integer ranging from 16 to 4294967294, in kbit/s.

Parameter

Description

Value

pir pir-value

Specifies the Peak Information Rate (PIR).

PIR: refers to the maximum number of packets that can be processed per second as well as the maximum bandwidth required to process packets.

The value is 0 or an integer ranging from 16 to 4294967294, in kbit/s.

If you do not specify pir pir-value, the pir-value value is equal to the cir-value value.
If you want to specify pir pir-value, ensure that the pir-value value is greater than or equal to the cir-value value.

pir-value and cir-value cannot be both 0s. If the cir-value value is 0, you must specify pir-value.

qos-profile qos-profile-name

Specifies the name of the referenced QoS profile.

The value is a string of 1 to 63 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed with double quotation marks (").

cir cir-value

Specifies the Committed Information Rate (CIR).

The CIR is the relatively minimum bandwidth. When the CIR is set, the following action is taken on packets:

Forward: forwards the packets whose traffic rate is lower than the CIR.
Discard: discards the packets whose traffic rate is higher than the PIR.
Re-mark: re-marks the packets whose traffic rate is between the CIR and PIR and allows these packets to be forwarded using the best effort model.

The value is 0 or an integer ranging from 16 to 4294967294, in kbit/s.

Usage Guidelines

Usage Scenario

When multiple VPN services share the same tunnel, bandwidth preemption occurs among these VPN services. Non-VPN traffic also preempts the bandwidth of VPN traffic. As a result, VPN traffic cannot be forwarded or dropped strictly based on service priorities.

The VPN services carried over a tunnel have different resource requirements. To meet the resource requirements of VPWS services carried over a tunnel without affecting the quality of other VPN services, configure VPWS QoS. To configures QoS parameters in a PW template, run the qos cir command.

Prerequisites

A PW template has been created and the PW template view is displayed using the pw-template command.

Precautions

On VPLS networks in BGP or BGP AD mode, VSIs do not have PW configurations. Therefore, VPLS networks in BGP or BGP AD mode support VSI-based VPN QoS rather than peer-based VPN QoS.

QoS parameter settings take effect only after the PW template is referenced by a PW.
QoS parameters configured using the qos cir command take effect without running the reset pw command.

Example

# Configure QoS parameters in the PW template named pw1.
