ZyXEL p-2802h-i1 Guia Do Utilizador

 Chapter 17 Quality of Service (QoS)

P-2802H(W)(L)-I Series User’s Guide

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.

Click Advanced > QoS to open the screen as shown next. 
Use this screen to enable or disable QoS, and select to have the ZyXEL Device automatically 
assign priority to traffic according to the IEEE 802.1p priority level, IP precedence and/or 
packet length. See 

 for more information.
