Section 4.2.9
When to Use
To set the Priority/Queue Mapping and Priority Regeneration for a particular port and also can be
used to change the default port priority used in the device.
NOTE: The priority is only changed while the device is processing the frame. Frames
received by the device with a 1p priority value are transmitted with that same value.
Priority/Queue Mapping is used to assign 802.1p priority values to the transmit (TX) queues
(0 through 3 with 0 being the lowest level TX queue) for each frame priority.
For example, if the TX queue is set to 3 for those frames with a priority 7, then those frames would
be transmitted before any frames contained in TX queues 2 through 0.
Priority Regeneration is used to classify different types of traffic by reprioritizing received frames
to a different transmit priority within the device. For example, the frames associated with a
particular type of traffic that have a received (RX) transmit priority, or a port default priority, of 3
could be changed to have a transmit priority of 5 out of the device.
