Description

Use the display qos lr interface command to display the LR configuration and statistics information of a certain interface or all interfaces.

If the interface argument is not specified, this command will display the LR configuration and statistics information of all the interfaces.

Example

# Display the LR configuration and statistics information of all the interfaces.

[H3C] interface GigabitEthernet 1/0/1

[H3C-GigabitEthernet1/0/1] qos sp

3.1.4  qos wrr

Syntax

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

undo qos wrr

View

Ethernet interface view/port group view

Parameter

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

group-id: It can only be 1.

weight schedule-value: Specifies the scheduling weight of a queue, rang from 1 to 15.

group sp: Configures SP queuing.

Description

Use the qos wrr weight command to configure the WRR queue or modify the parameters of the WRR queue on the port.

Use the undo qos wrr command to restore the default queue-scheduling algorithm on the port.

By default, the switch adopts the WRR queue-scheduling algorithm.

As required, you can configure part of the queues on the port to adopt the SP queue-scheduling algorithm and parts of queues to adopt the WRR queue-scheduling algorithm. Through adding the queues on a port to the SP scheduling group and WRR scheduling group (namely, group 1), the SP+WRR queue scheduling is implemented. During the queue scheduling process, the queues in the SP scheduling group is scheduled preferentially. When no packet is to be sent in the queues in the SP scheduling group, the queues in the WRR scheduling group are scheduled. The queues in the SP scheduling group are scheduled according to the strict priority of each queue, while the queues in the WRR queue scheduling group are scheduled according the weight value of each queue.

Related command: display qos wrr interface.

Example

# Apply the SP+WRR queuing on GigabitEthernet 1/0/1 and set queue 0 to sp and queue 1 to WRR with a weight of 10.
