Quality of Service

Quality of Service (QoS) provides the ability to implement priority queuing within a network. QoS enables traffic to be prioritized, while excessive broadcast and multicast traffic to be avoided. Traffic, such as Voice and Video streaming, which requires a minimal delay can be assigned to a high priority queue, while other traffic can be assigned to a lower priority queue resulting in uninterrupted actions.

State Select whether QoS is enabled or disabled on the switch.
Scheduling Method

Selects the Strict Priority or WRR to specify the traffic scheduling method.

  • Strict Priority – Specifies traffic scheduling based strictly on the queue priority.

  • WRR – Use the Weighted Round-Robin (WRR) algorithm to handle packets in priority classes of service. It assigns WRR weights to queues.
Trust Mode

Select which packet fields to use for classifying packets entering the Switch.

  • DSCP – Classify traffic based on the DSCP (Differentiated Services Code Point) tag value.

  • 1p–Classify traffic based on the 802.1p. The eight priority tags that are specified in IEEE802.1p are from 1 to 8.
