Priority
IEEE 802.1p defines up to 8 separate traffic classes. This switch
supports Quality of Service (QoS) by using two priority queues,
with Weighted Fair Queuing for each port. You can use the Priority
Menu to configure the default priority for each port, or to display
the mapping for the traffic classes.
Port Priority Configuration
The default priority for all ingress ports is zero. Therefore, any
inbound frames that do not have priority tags will be placed in the
low priority output queue. Default priority is only used to
determine the output queue for the current port; no priority tag is
actually added to the frame. You can use the Port Priority
Configuration screen to adjust default priority for any port as
shown below.
Parameter Description

where 0~3 specifies the low priority q ueue and 4~7

queues.
