QoS Configuration
In general, traffic on networks is treated as the same priority and delivered equally. With
QoS enabled, users can classify frames or packets into different priority to ensure
specific network traffic is delivered on a foundation of best-effort. The incoming frames or
packets can be sent to different priority queues for different priority service according to
the configured polices.
►QoS Policy
Select one of the two radio buttons to determine the QoS policy—an 8-4-2-1 weighted fair
queuing scheme or a strict priority scheme. The 8-4-2-1 weighed fair queuing scheme
designed with four queues to which allocate traffic in the rate of 8:4:2:1. As for the strict
priority scheme, traffic will be identified according to the priority determined.

Qos Policy: Select the QoS policy rule.

Use an 8,4,2,1 weighted fair queuing scheme: The switch will follow the ratio
of 8:4:2:1 to process priority queues including High, Middle, Low and Lowest.
For example, while the system processing, 1 frame in the lowest queue, 2
frames in the low queue, 4 frames in the middle queue, and 8 frames in the high
queue will be processed at the same time in accordance with the 8,4,2,1 policy
rule.

Use a strict priority scheme: With this radio button selected, you have to click
the pull-down menu labeled ‘Priority Type’.

Priority Type: Five options— Port-based , TOS only , COS only , TOS first , and
COS first are provided except ‘Disable’. Disable means QoS function is not
activated.

Click Apply to have the configuration take effect.
