qos

Function

The qos cir command configures QoS parameters for a VSI.

The undo qos command deletes the configuration of QoS parameters for a VSI.

By default, QoS parameters are not configured for a VSI.

Format

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

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

Parameters

Parameter	Description	Value
pir pir-value	Specifies the PIR.	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. -In a cross-NP module scenario, the pir-value doubles.
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 CIR.	The value is 0 or an integer ranging from 16 to 4294967294, in kbit/s.

Parameter

Description

Value

pir pir-value

Specifies the PIR.

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.

-In a cross-NP module scenario, the pir-value doubles.

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 CIR.

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

Usage Guidelines

Usage Scenario

In an L2VPN scenario, if 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 strictly based on service priorities.

To meet the resource requirements of VPLS services carried over a tunnel without affecting the quality of other VPN services, you can configure VPLS QoS. To configure QoS parameters for a VSI, run the qos cir command. The configuration takes effect to all PWs in the VSI.

Prerequisites

A VSI has been created, or the VSI view has been displayed using the vsi command.

Precautions

The qos cir (VSI view) command is mutually exclusive with the following commands:

qos cir (VSI-LDP-PW view)
pbb i-vsi enable
pbb b-vsi enable
mld-snooping enable
igmp-snooping enable

Only the NetEngine 8000 F1A supports PBB VPLS.

Example

# Configure QoS parameters in the VSI view.

<HUAWEI> system-view

[*HUAWEI] mpls l2vpn
[*HUAWEI-l2vpn] quit
