physical and virtual ports. If the number of ports exceeds 12 ports, then other ports can be
displayed using the NEXT command.
With this screen, you can also select a port and access the Traffic Class Configuration screen,
which allows you to change the Traffic Class (0 -3, with 0 being the lowest level) for each priority
of the selected port. Then you can apply the new settings to either the selected port or to all the
ports.
NOTE: The priority is only changed while the switch module is processing the frame.
Frames received by the switch module with a 1p priority value are transmitted with that
same value.
