8.3TRAFFIC CLASS INFORMATION SCREEN

When to Use

To view the current mapping of the Traffic Class-to-priority for each port, which can include both 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 SmartSwitch device is processing the frame. Frames received by the SmartSwitch device with a 1p priority value are transmitted with that same value.

Priority-to-Traffic Class Mapping is used to assign 802.1p priority values to a Traffic Class (0 through 3 with 0 being the lowest level Traffic Class) for each frame priority.

For example, if the Traffic Class is set to 3 for those frames with a priority 7, then those frames would be transmitted before any frames contained in Traffic Classes 2 through 0.
