remark dscp (QoS profile view)

remark dscp (QoS profile view)

Function

The remark dscp command configures an action of re-marking the DSCP priority in IP packets in a QoS profile.

The undo remark dscp command deletes the configuration.

By default, an action of re-marking the DSCP priority in IP packets is not configured in a QoS profile.

Format

remark { inbound | outbound } dscp { dscp-name | dscp-value }

undo remark { inbound | outbound } dscp

Parameters

Parameter

Description

Value

inbound

Re-marks the DSCP priority in IP packets in the inbound direction.

-

outbound

Re-marks the DSCP priority in IP packets in the outbound direction.

-

dscp-name

Specifies the DSCP priority name in IP packets.

The value can be ef, af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, or default.

dscp-value

Specifies the DSCP priority in IP packets.

The value is an integer that ranges from 0 to 63. A larger value indicates a higher priority.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

To provide differentiated services based on the DSCP priority of packets, run the remark dscp command to configure the device to re-mark the DSCP priority of the packets.

Follow-up Procedure

Run the qos-profile (user group view) command in the user group view to bind the user group to the corresponding QoS profile that has DSCP priority re-marking configured.

Precautions

If a traffic policy containing remark dscp is applied to the outbound direction on an interface, the device still processes outgoing packets based on the original priority but the downstream Layer 3 device or above processes the packets based on the re-marked priority.

If you run the remark dscp command repeatedly in the same QoS profile view, only the latest configuration takes effect.

Example

# Re-mark the DSCP priority in IP packets in the inbound direction as 56 in the QoS profile view.

<Huawei> system-view
[Huawei] qos-profile name name1
[Huawei-qosprofile-name1] remark inbound dscp 56
