Like other Vigor Routers, Vigor2750 provides 4 traffic classes: High, Medium, Normal
and Low. The non-matching packets will be categorized to the default class (default is
Normal).
1. The first step to enable QoS is to set the correct WAN TX/RX Rate in Port Rate
Control page.
Policer Enabled option means to enable QoS for the RX/ Incoming direction.
Shaper Enabled option means to enable QoS for the TX/ Outgoing direction.
2. Then, configure the ports or protocols with specific traffic class value. Open
Bandwidth Management >>QoS Control List. The default QoS configuration is like
below.
