QoS
Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control
over network traffic. QoS enables you to assign various grades of network service to different types of
traffic, such as multi‐media, video, protocol‐specific, time critical, and file‐backup traffic.
QoS reduces bandwidth limitations, delay, loss, and jitter. It also provides increased reliability for delivery
of your data and allows you to prioritize certain applications across your network. You can define exactly
how you want the switch to treat selected applications and types of traffic.
You can use QoS on your system to control a wide variety of network traffic by:
Classifying traffic based on packet attributes.
Assigning priorities to traffic (for example, to set higher priorities to time‐critical or business‐
critical applications).
Applying security policy through traffic filtering.
Provide predictable throughput for multimedia applications such as video conferencing or Voice
over IP by minimizing delay and jitter.
Improve performance for specific types of traffic and preserve performance as the amount of
traffic grows.
Reduce the need to constantly add bandwidth to the network.
Manage network congestion.

Port‐based Priority
Port‐based priority QoS allows you to assign a priority level to each of the 8 ports. The priority levels are:
lowest, medium, normal, and highest. By default, all ports are set to priority group 1 (lowest).
Select the port from the left, then choose a priority level from the drop down list on the right, and then
click ‘Apply’ to save the priority level for the port.

DESCRIPTION
Port
Select the desired port for configuration. Hold down CTRL to select multiple ports
at once.
Priority Queue
Specify the priority queue for that port. The priorities are labeled as 1~4. The
higher the value, the higher the priority.
