Configure Scheduling

When congestion occurs on a network, queue scheduling solves the resource preemption problem among multiple packets.

Context

Procedure

1. Choose QoS > Congestion Management > Configure Scheduling in the navigation tree to open the Configure Scheduling page.

   Table 1 describes the parameters on the Configure Scheduling page.

   Table 1 Configure Scheduling

   Parameter	Description
   Select Interface	Indicates the interface where scheduling needs to be configured. You can select multiple interfaces.
   Queues	Indicates the queue where scheduling needs to be configured.
   Scheduling Mode	Indicates the queue scheduling mode, including: PQ In PQ mode, the switch schedules packets based on priorities of queues in a strict manner. The weight is not used in this mode. DRR In RR mode, the switch schedules packets circularly based on priorities of queues. Based on RR scheduling, DRR scheduling is used to schedule packet flows of all the queues according to the maximum bandwidth assigned by the switch to the queues. WRR Based on RR scheduling, WRR scheduling is used to schedule packet flows based on weights of queues. The default value is wrr.
   Weight	Indicates the weight used to schedule packet flows in queues.

2. Select the interfaces that you want to configure.
3. Set the scheduling mode and weight for the queue.
4. Click Apply to complete the configuration.
