the smart switch supports quality of service (qos) by using two priority queues for each port. the priority setting determines the order in which the port forwards packets. each port is associated with a traffic class: low and high priority level. use the screen as below to set the priority for a port.
when you power on the switch, the default port priority function is disabled.
the port priority function is not allowed to enable if port trunking function is enabled simultaneously.
press [ctri+d] to refresh as default port priority configuration.
port priority function is not available for the 17th 100base-fx fiber port.
