Setting Up QoS

Quality of Service (QoS) provides the ability to implement priority queuing within a network. QoS enables traffic to be prioritized, while minimizing excessive broadcast and multicast. 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.

To set up QoS for a Switch

1. Navigate to DEVICE > Switch Network > Switches and click on QoS.

   

2. Set Egress Policy.

   The first screen details Egress Policy which applies for all approaches to packet and traffic classification.In the preceding UI screen, the State slider determines whether QoS is enabled (to the right) or disabled (to the left). Scheduling method can be set as Strict Priority based on Queue number or as Weighted Round Robin (WRR). The classification of packets can be set as 802.1p or DSCP (Differentiated Sevices Code Point), or as both.

3. Select the IPDSCP screen to set DSCP codes to specific Queues.

   

4. To set class of service, click on CoS.

   In the CoS (Class of Service) screen, the CoS priority tag values, where 0 is the lowest and 7 is the highest are related to eight traffic priority queues from 1 to 8, where one is the lowest priority and eight is the highest priority.
