Huawei quidway s7700 - Optional) Setting the Length of the Interface Queue; Setting the Scheduling Mode for an Interface Queue

3.3.2 (Optional) Setting the Length of the Interface Queue
This section describes how to set the length of the interface queue and the length of the specified
priority queue.
Context
The length of the interface priority queue is automatically managed by the system. You can set
the length of the interface priority queue as required by using the qos queue command.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Step 3 Run:
qos queue queue-index length length-value
The length of the interface priority queue is set.
NOTE
The queue length cannot be set on G48SBC boards and W series boards.

3.3.3 Setting the Scheduling Mode for an Interface Queue
The S7700 supports the following scheduling modes: PQ, DRR, WRR, PQ+DRR, and PQ
+WRR.
Context
The S7700 supports eight interface queues that can use different scheduling algorithms. During
queue scheduling, packets in a PQ queue are first scheduled. If there are multiple PQ queues,
the packets are scheduled in descending order of priorities of these PQ queues. After packets in
PQ queues are scheduled, packets in WRR queues are scheduled in a polling manner.
If you need to set the same scheduling parameters on multiple interfaces, you can perform the
configuration on the port group to reduce the workload.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
