View

Any view

Parameters

interface-type: Port type.

interface-number: Port number.

Description

Use the display qos lr interface command to display the line rate configuration information of a certain interface or all interfaces.

If the interface argument is not specified, this command will display the line rate configuration information of all the interfaces.

Examples

# Display the line rate configuration and statistics information of all the interfaces.

<Sysname> display qos lr interface

Interface: GigabitEthernet0/0/1

Direction: Outbound

 CIR 6400 (kbps),  CBS 400000 (byte)

Table 1-1 Description on the fields of the display qos lr command

Field	Description
Interface	Port name, composed of port type and port number
Direction	Specify the direction of limited rate as outbound
CIR	Committed information rate, in kbps
CBS	Committed burst size, in byte

 

qos lr outbound

Syntax

qos lr outbound cir committed-information-rate [ cbs committed-burst-size ]

undo qos lr outbound

View

Parameters

outbound: Limits the rate of the outbound traffic.

cir committed-information-rate: Specifies the committed information rate (CIR) in kbps. The range of CIR varies with port types as follows:

l          GigabitEthernet port: 64 to 1000000

l          Ten-GigabitEthernet port: 64 to 10000000

Note that the committed-information-rate argument must be a multiple of 64.

cbs committed-burst-size: Specifies the committed burst size in bytes.

l          The committed-burst-size argument ranges from 4000 to 16000000.

qos sp

Syntax

qos sp

undo qos sp

View

Ethernet interface view, port group view

Parameters

None

Description

Use the qos sp command to configure SP queuing on the current port.

Use the undo qos sp command to restore the default queuing algorithm on the port.

By default, all the ports adopt the WRR queue scheduling algorithm, with the weight values assigned to queue 0 through queue 7 being 1, 2, 3, 4, 5, 9, 13, and 15.

Related commands: display qos sp interface.

Examples

# Configure SP queuing on GigabitEthernet0/0/1.

<Sysname> system-view

[Sysname] interface GigabitEthernet 0/0/1

[Sysname-GigabitEthernet0/0/1] qos sp

qos wrr

Syntax

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

undo qos wrr

View

Ethernet interface view, port group view

Parameters

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

group-id: It can only be 1.

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

sp: Configures SP queuing.

Description

Use the qos wrr command to configure Weighted Round Robin (WRR) queue scheduling algorithm or the SP + WRR queue scheduling algorithm on a port or port group.

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

By default, all the ports adopt the WRR queue scheduling algorithm, with the weight values assigned to queue 0 through queue 7 being 1, 2, 3, 4, 5, 9, 13, and 15.

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 commands: display qos wrr interface.

Examples

# Configure SP+WRR queue scheduling algorithm on GigabitEthernet 0/0/1 as follows: assign queue 0, queue 1, queue 2, and queue 3 to the SP scheduling group; and assign queue 4, queue 5, queue 5, and queue 7 to WRR scheduling group, with the weight 2, 4, 6, and 8.
