17.1.4 Automatical Priority Queue Assignment

If you enable QoS on the ZyXEL Device, the ZyXEL 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 ZyXEL
Device. On the ZyXEL Device, traffic assigned to higher priority queues gets through faster
while traffic in lower index queues is dropped if the network is congested.
