Vigor2900 Series User’s Guide

Vigor routers as edge routers of DS domain shall check the marked DSCP value in the IP
header of bypassing traffic, thus to allocate certain amount of resource execute appropriate
policing, classification or scheduling. The core routers in the backbone will do the same
checking before executing treatments in order to ensure service-level consistency throughout
the whole QoS-enabled network.
However, each node may take different attitude toward packets with high priority marking
since it may bind with the business deal of SLA among different DS domain owners. It’s not
easy to achieve deterministic and consistent high-priority QoS traffic throughout the whole
network with merely Vigor router’s effort.
The following QoS policies will be defined in the form of ratio of upstream/downstream speed.
We will also provide application QoS requirement as reference to help you accomplish this
task. The setting values will vary depending on the network condition.
Click on QoS Control on the Advanced Setup group. The following screen will appear.
WAN Inbound Bandwidth Type the inbound bandwidth for WAN interface.
WAN Outbound Bandwidth Type the outbound bandwidth for WAN interface.
Enable the QoS Control For V models, the factory default for this is checked to enable.
Direction Define which traffic the QoS Control settings apply to.
IN- apply to incoming traffic only.
OUT-apply to outgoing traffic only.
BOTH- apply to both incoming and outgoing traffic.
Index The group index number of QoS Control settings. There are
total 4 groups.
Class Name Define the name for the group index.
