to select ON or OFF. Set FlowCtrl to ON to avoid data transfer

(3) QoS
Quality of Service (QoS) is a networking term that specifies a
guaranteed throughput level. When data packets with QoS
priority information pass through QoS supported device, these
packets will be handled with priority. Without certain level of
QoS, multimedia applications such as Streaming Video and
Network Conference can be sluggish or stopped due to network
congestions.
This Switch supports IEEE 802.1p QoS Tagging and Port-Based
QoS. It exams each packet for IEEE 802.1p priority tag, if the tag
value is higher than 3, the packet has high priority; otherwise, the
packet has low priority. If the packet has no priority tag, it will
handle the packet according to the priority code (high or low) of
the port.
Note: IEEE 802.1p Priority Tag supersedes the Port-Based
Priority setting. For example, if Port 1 is set to low priority, but
the packet coming in this port has high priority tag, the Switch
will consider the packet as high priority packet.
The default settings for all ports' QoS are High. To change the
Port-Based QoS setting, select the Port number, highlight the
QoS field, and hit Space Bar to select High or Low.
QoS Example: The computers connect to Switch's Port 1 ~ 5 do
Video Conferencing regularly. To ensure video/voice streaming
quality between these 5 Users, you can set Port 1 ~ 5 QoS to
High and set the rest of the ports' QoS to low.
