LABEL DESCRIPTION
QoS 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 VMG
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 VMG to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the VMG automatically sets this number to be 95% of the WAN
interfaces’ actual upstream transmission speed.
LAN Managed
Downstream
Bandwidth
Enter the amount of downstream bandwidth for the LAN interfaces (including WLAN) that
you want to allocate using QoS.
The recommendation is to set this speed to match the WAN interfaces’ actual transmission
speed. For example, set the LAN managed downstream bandwidth to 100000 kbps if you
use a 100 Mbps wired Ethernet WAN connection.
You can also set this number lower than the WAN interfaces’ actual transmission speed. This
will cause the VMG to not use some of the interfaces’ available bandwidth.
If you leave this field blank, the VMG automatically sets this to the LAN interfaces’ maximum
supported connection speed.
Upstream
Traffic Priority
Assigned by
Select how the VMG assigns priorities to various upstream traffic flows.
• None: Disables auto priority mapping and has the VMG put packets into the queues
according to your classification rules. Traffic which does not match any of the
classification rules is mapped into the default queue with the lowest priority.
• Ethernet Priority: Automatically assign priority based on the IEEE 802.1p priority level.
• IP Precedence: Automatically assign priority based on the first three bits of the TOS
field in the IP header.
• Packet Length: Automatically assign priority based on the packet size. Smaller packets
get higher priority since control, signaling, VoIP, internet gaming, or other real-time
packets are usually small while larger packets are usually best effort data packets like
file transfers.
