By default, no priority queue is established.

3Configure the default priority-list queuing.

The data packets that are not matched with any policy in the priority queue (both protocol type and interface type are not matched) will be allocated to the default priority queue.

Please perform the following configurations in the system view.

Table 724 Configure the Default Priority-List Queuing

Operation	Command
Configure the default priority-list queuing	qos pql pql-indexdefault-queue { top
	middle normal bottom }
Recover the default priority of the priority	undo qos pql pql-indexdefault-queue
queue

By default, no default priority queue is established.

Multiple policies may be defined for the group of the priority queues, which is then applied to an interface. When the data packet arrives at the interface, the data packet is matched by the system according to the configured policy. The data packet is inputted into the specified queue if it matches with the policy. If the data packet does not match with any policy, it is inputted into the default priority queue. If the default priority queue is not configured, the default priority queue group is 16 with the priority level as normal.

Applying the priority-list queuing group to the interface

To put the priority queue into function, the configured priority queue group must be applied to the specific interface. Every interface can only use one priority queue group, but one priority queue can be applied to multiple interfaces. Multiple different priority queues group can be established to apply to different interfaces.

Perform the following configurations in the interface view.

By default, the interface utilizes the FIFO queue.

Specifying the queue length of the priority-list queuing

The queue length of each priority queue (the maximum number of the data packets that may be accommodated) can be specified.

Perform the following configurations in the system view.
