cos

Function

The cos command displays a queue priority sub-view of a flow queue profile in enhanced 8-CoS mode.

The undo cos command restores the default configuration in a queue priority sub-view of a flow queue profile in enhanced 8-CoS mode.

By default, the default configurations of eight queue priority sub-views exist in a flow queue profile in enhanced 8-CoS mode.

Usage Guidelines

Usage Scenario

You can configure scheduling parameters (including a scheduling priority, weight, CIR, PIR, and drop policy) for eight priority flow queues in a flow queue profile in enhanced 8-CoS mode, providing differentiated QoS guarantee for service traffic with different priorities.

Prerequisites

Before configuring scheduling parameters for a user queue with a specified priority, you must run this command to enter the queue priority sub-view.

Precautions

Only CR5DNPU48071/CR5DNPU1TM71 boards support a flow queue profile in enhanced 8-CoS mode.

Example

# Display the priority sub-view of the queue with CoS 1 of a flow queue profile in enhanced 8-CoS mode.
