What is the VIP QoS of SSID Advanced settings?

Zyxel_JoyLee

VIP QoS (Quality of Service) allows you to set the priority for traffic sent by Wi-Fi clients on a specific Wi-Fi network (SSID). This helps ensure that certain types of data, such as voice or video, receive preferential treatment to maintain quality.

The incoming traffic can be mapped to specific Access Category and Priority Queue for differentiated forwarding treatment.

￭WMM (Auto)-This stands for Wi-Fi Multimedia and assigns a default priority to network traffic that is not sensitive to delays.

Auto SSID traffic is mapped to Best Effort Category

￭Gold (Voice)-This option assigns the highest priority to delay-sensitive traffic, such as voice communications, to ensure clear and uninterrupted calls.

Gold SSID traffic is mapped to Voice Category

￭Silver (Video)-This option assigns the second-highest priority to traffic that can tolerate some moderate delay, such as video streaming, to reduce buffering and improve viewing experience.

Silver SSID traffic is mapped to Video Category

By assigning higher priority levels, clients can access wireless medium faster & experience lower latency

￭The QoS behavior before no VIP QoS of SSID Advanced settings:

•If traffic is marked as Voice type (via 802.1p) by a switch, the AP maps it to the Voice Category (AC_VO) queue and prioritize for transmission.

￭The QoS behavior with VIP QoS of SSID Advanced settings:

•When VIP QoS is set to Auto, AP reads the incoming packet’s QoS tag and queues the traffic based on its corresponding QoS marking

If the traffic is classified as Voice Category, it will be mapped to the Voice queue,

even when the SSID Priority is set to Auto

•When VIP QoS is set to Gold or Silver, AP queues the incoming traffic based on the configured SSID Priority rather than the original QoS tag carried in the packet.
