3.1.3 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 GigabitEthernet1/0/1.

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

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 1/0/1 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.
