display flow-wred configuration

Function

The display flow-wred configuration command displays information about flow queue WRED objects. The information includes the upper threshold, lower threshold (both of which are in percentage), and drop percentage of different colors of packets and whether the WRED objects are used.

Format

display flow-wred configuration [ verbose [ flow-wred-name ] ]

Parameters

Parameter	Description	Value
verbose	Display verbose configuration information.	-
flow-wred-name	Specifies the name of a flow queue WRED object.	The value is a string of 1 to 31 characters.

Parameter

Description

Value

Usage Guidelines

Usage Scenario

You can run the display flow-wred configuration command in the following three manners:

If you run the display flow-wred configuration command, the system outputs a summary of all the flow queue WRED objects.
If you run the display flow-wred configuration verbose command, the system outputs detailed information about all the flow queue WRED objects.
If you run the display flow-wred configuration verbose <flow-wred-name> command, the system outputs detailed information about a specified flow queue WRED object.
If no flow queue WRED objects are configured through the flow-wred command, you are notified by a message indicating that the number of flow queue WRED objects is 0 after running the display flow-wred configuration command.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display flow-wred configuration** command output
Item	Description
Flow wred name	Indicates the name of the flow queue WRED object.
Color	Indicates the color (green, yellow or red) of packets.
Low-limit	Indicates the lower threshold (in percentage). The percentage is the proportion of the actual length of a packet queue to the length of a flow queue. The system begins to drop packets at the percentage specified by discard-percent when the percentage exceeds the lower threshold.
High-limit	Indicates the upper threshold (in percentage) set for the queue. The percentage is the proportion of the actual length of a packet queue to the length of a class queue. The system drops all the subsequent packets when the percentage exceeds the upper threshold.
Discard-percent	Indicates the percentage of packets being dropped. The system drops packets according to this percent when the proportion of the actual length of a packet queue to the length of a flow queue is between the lower threshold and the upper threshold.
Queue Depth(kbytes)	Queue depth(Unit: kbytes).
Reference relationships	Indicates that the flow queue WRED objects are used by which flow queue templates.
total number	Indicates the number of created flow queue WRED objects.
flow-wred-name	Indicates the name of the flow queue WRED object.
is-used	Indicates that whether the flow queue WRED object is used. The value can be yes or no.
