LABEL DESCRIPTION
QoS State Select the Enable check box to turn on QoS to improve your network performance.
WAN Managed
Upstream
Bandwidth Enter the amount of upstream bandwidth for the WAN interfaces that you want to allocate
using QoS.
The recommendation is to set this speed to match the interfaces’ actual transmission speed.
For example, set the WAN interfaces’ speed to 100000 kbps if your Internet connection has
an upstream transmission speed of 100 Mbps.
You can set this number higher than the interfaces’ actual transmission speed. The
EMG3425-Q10A 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 interfaces’ actual transmission speed. This will
cause the EMG3425-Q10A to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the EMG3425-Q10A automatically sets this number to be 95%
of the WAN interfaces’ actual upstream transmission speed.
