queue priority

Function

The queue priority command sets scheduling parameters for a flow queue, including the queue priority, shaping value, and flow-WRED settings.

The undo queue priority command restores default scheduling parameters for a flow queue.

By default, the default priority values of queues are used.

Format

queue cos-value { priority priority-value [ weight weight-value ] | { shaping { shaping-value | shaping-percentage shaping-percentage-value } [ pbs pbs-value ] } | flow-wred wred-name } ^*

undo queue cos-value [ priority | shaping | flow-wred ]

Parameters

Parameter	Description	Value
cos-value	Specifies the service class of a flow queue.	The value can be cs7, cs6, ef, af4, af3, af2, af1, or be.
priority-value	Specifies the priority value. Rate limiting is implemented based on the priority value.	The value is an integer ranging from 0 to 3. The smaller the value, the higher the priority.
weight weight-value	Specifies the WFQ scheduling weight.	The value is an integer ranging from 1 to 100.
shaping-value	Specifies the PIR value, which reflects the shaping bandwidth configured on an interface.	The value is an integer ranging from 8 to 4294967294, in kbit/s.
shaping-percentage shaping-percentage-value	Specifies the shaping rate percentage. The shaping rate percentage refers to the percentage of shaping rate in PIR.	The value is an integer ranging from 0 to 100.
pbs pbs-value	Specifies the depth of a shaping token bucket.	The value is an integer ranging from 1 to 4194304.
flow-wred wred-name	Specifies the name of a WRED object used by a flow queue.	The value is a string of 1 to 31 characters.

Usage Guidelines

Usage Scenario

To set scheduling parameters for a flow queue, including the queue priority, weight, shaping value, and flow-WRED settings, run the queue priority command.

**Table1 ** Default priority values of flow queues

Flow Queue	Priority Value	weight
BE	3	10
AF1	2	10
AF2	2	10
AF3	1	10
AF4	1	10
CS6	0	10
CS7	0	10
EF	0	10

Prerequisites

A priority-based flow queue has been created.

Configuration Impact

Queue scheduling of services is affected.

Example

# Set the priority of the EF queue to 2, weight to 20, and shaping value to 10 Mbit/s in the priority-based flow queue profile named test1.
