qos { pq | wrr | drr } (network QoS profile view)

Function

The qos { pq | wrr | drr } command configures the queue scheduling mode for an AS port.

The undo qos { pq | wrr | drr } command restores the default queue scheduling mode of an AS port.

By default, no interface queue scheduling mode is configured in the network QoS profile view.

This command can only be executed on a parent switch.

Format

qos { pq | wrr | drr }

undo qos { pq | wrr | drr }

Usage Guidelines

Usage Scenario

When congestion occurs on a network, configure the interface queue scheduling mode to balance between the delay and jitter of various service packets. In this way, packets of delay-sensitive services, such as voice and video services, can be processed preferentially. Among delay-insensitive services, such as the email service, the packets with the same priority are processed equally and the packets with different priorities are processed based on their weights.

In an SVF system, to change the queue scheduling mode of an AS port, run the qos { pq | wrr | drr } command in the network QoS profile view and then bind the profile to the AS port.

Precautions

If the queue scheduling weight has been configured using the qos queue command before the queue scheduling mode is configured, delete the configured queue scheduling weight first.

Example

# Set the queue scheduling mode of an AS port to WDRR.
