Chapter 15 Quality of Service (QoS) Use this screen to enable or disable QoS and set the default DSCP value for incoming traffic does not match a class. See Section 15.1 on page 163 for more information. Figure 92 QoS General The following table describes the labels in this screen. Table 62 QoS General LABEL Active QoS WAN Managed Upstream Bandwidth DESCRIPTION Select the check box to turn on QoS to improve your network performance. Enter the amount of upstream bandwidth for the WAN interface that you want to 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 100000 kbps if your Internet connection has an upstream transmission speed of 100 Mbps. You can set this number higher than the interface's actual transmission speed. The ZyXEL Device uses up to 95% of the DSL port's actual upstream transmission speed even if you set this number higher than the DSL port's actual transmission speed. 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. Apply Cancel If you leave this field blank, the ZyXEL Device automatically sets this number to be 95% of the DSL port's actual upstream transmission speed. Click Apply to save your changes back to the ZyXEL Device. Click Cancel to begin configuring this screen afresh. P-870H/HW Series User's Guide 165
