Command Usage
•
This switch provides four priority queues for each port. It uses
Weighted Round Robin to prevent head-of-queue blockage.

•
The default priority applies if the incoming frame is an untagged frame
received from a VLAN trunk or a static-access port. This priority does
not apply to IEEE 802.1Q VLAN tagged frames. If the incoming
frame is an IEEE 802.1Q VLAN tagged frame, the IEEE 802.1p User
Priority bits will be used.

Priority bits will be used.
•
If the output port is an untagged member of the associated VLAN,
these frames are stripped of all VLAN tags prior to transmission.
