3.10 Description of priority determination

Priority determination is functionality that uses CoS values to specify the priority of frames detected by flow detection in order to determine the send queue. Frames to which this functionality applies differ depending on the switch configuration and the setting for changing which frames are subject to priority determination. For details, see section 3.10.1, Frames Subject to Priority Determination.

The following figure shows the positioning of the priority determination block described in this section.
