Chapter 16 Quality of Service (QoS)
16.2 The QoS General Screen
Use this screen to enable or disable QoS and have the ZyXEL Device automatically assign priority to traffic according to the IEEE 802.1p priority level, IP precedence and/or packet length.
Click Advanced > QoS to open the screen as shown next.

LABEL | DESCRIPTION |
Active QoS | Select the check box to turn on QoS to improve your network |
| performance. |
| You can give priority to traffic that the ZyXEL Device forwards out through |
| the WAN interface. Give high priority to voice and video to make them |
| run more smoothly. Similarly, give low priority to many large file |
| downloads so that they do not reduce the quality of other applications. |
|
|
WAN Managed | Enter the amount of bandwidth for the WAN interface that you want to |
Bandwidth | allocate using QoS. |
| The recommendation is to set this speed to match the interface’s actual |
| transmission speed. For example, set the WAN interface speed to 1000 |
| kbps if your Internet connection has an upstream transmission speed of 1 |
| Mbps. |
| You can set this number higher than the interface’s actual transmission |
| speed. This will stop lower priority traffic from being sent if higher priority |
| traffic uses all of the actual bandwidth. |
| You can also set this number lower than the interface’s actual |
| transmission speed. This will cause the ZyXEL Device to not use some of |
| the interface’s available bandwidth. |
