2. Select the queue to map to the predefined 802.1p priority values.
The 802.1p Priority row contains traffic class selectors for each of the eight 802.1p
priorities to be mapped. The priority goes from low (0) to high (7). For example, traffic with
a priority of 0 is for most data traffic and is sent using “best effort.” Traffic with a higher
priority, such as 6, might be time-sensitive traffic, such as voice or video.
The values in each drop down menu represent the traffic class. The traffic class is the
hardware queue for a port. Higher traffic class values indicate a higher queue position.
Before traffic in a lower queue is sent, it must wait for traffic in higher queues to be sent.
