Parameter

interface-type: Port type.

Description

Use the display qos wrr interface command to display the weighted round robin (WRR) queue information about a port.

If no ports are specified, this command displays the WRR information about all the ports.

Related command: qos wrr.

Example

# Display the WRR information about Ethernet1/0/1 port.

<Sysname> display qos wrr interface Ethernet 1/0/1

Interface: Ethernet1/0/1

Output queue: Weighted round robin queue

Table 3-1 Description on the fields of the display qos wrr interface command

Field	Description
Interface	Port name, comprising of port type and port number
Output queue	Type of the current output queues
Queue ID	Queue number
Group	ID of the group which a queue belongs to
Weight	Queue weight N/A indicates that the queue adopts the SP queue scheduling algorithm

3.1.2 qos wrr

Syntax

qos wrr queue-id group { group-id weight queue-weight | sp }

undo qos wrr

View

Ethernet port view, port group view

Parameter

queue-id: Output queue ID, in the range of 0 to 7.

group group-id: Specifies a WRR priority group. The group-id argument can be 1 or 2. The WRR priority groups are scheduled by priority.

weight queue-weight: Specifies weight for the queue. The queue-weight argument is in the range 8 to 100.

sp: Specifies the SP queue scheduling algorithm.

Description

Use the qos wrr command to configure the WRR or SP + WRR queue scheduling algorithm for a port or port group.

Use the undo qos wrr command to restore the default.

By default, all the output queues of a port are scheduled using the strict priority (SP) algorithm.

A port on an S3610 and S5510 switch supports eight output queues. Different queues can adopt different queue scheduling algorithms. As required, you can configure part of the queues on a port to adopt the SP queue scheduling algorithm and part of the queues to adopt the WRR queue scheduling algorithm. The SP+WRR queue scheduling algorithm is implemented by adding queues on a port to SP scheduling queues and WRR queue scheduling queues respectively. For example, queue 0 and queue 1 are in the SP queue scheduling group, and queue 2, queue 3, and queue 4 are in the WRR queue scheduling group 1, queue 5, queue 6, and queue 7 are in WRR queue scheduling group 2. Round robin is performed in WRR group 2 firstly. If no packet is to be sent in WRR group 2, round robin is performed in WRR group 1. At last, packets in the SP queue scheduling group are processed.

Caution:

With WRR or SP + WRR queue scheduling algorithm adopted, the queues assigned to the same queue scheduling group must be with consecutive queue numbers.

Example

# Enable the SP+WRR queue scheduling algorithm on Ethernet1/0/1. Add queue 0 and queue 1 to the SP queue scheduling group; add queue 2, queue 3, and queue 4 to WRR queue scheduling group 1, with the weight being 20, 70, and 100 respectively; add queue 5, queue 6, and queue 7 to WRR queue scheduling group 2, with the weight being 10, 50, and 80 respectively.

View

Ethernet port view, port group view

Parameters

queue queue-id: Specifies a queue ID, in the range 0 to 7.

length queue-length: Specifies the queue length, in the range of 1 to 256.

Description

Use the burst-traffic command to set the queue length on the port or port group to adjust the capability of processing burst traffic.
