Chapter 10 Quality of Service (QoS)
VSG1432-B101 Series User’s Guide
168
Automatic 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.
