 Chapter 15 Quality of Service (QoS)

AMG1302-T10A User’s Guide

If you enable QoS on the Device, the Device can automatically base on the IEEE 802.1p priority 

level, IP precedence and/or packet length to assign priority to traffic which does not match a class.

The following table shows you the internal layer-2 and layer-3 QoS mapping on the Device. On the 

Device, traffic assigned to higher priority queues gets through faster while traffic in lower index 

queues is dropped if the network is congested.
