Bandwidth Management adjusts the bandwidth settings for upstream and downstream traffic and configures Quality of Service (QoS) settings for various types of traffic, such as voice services.
Note If you do not add any rule of QoS, then the total WAN bandwidth is not limited to the configured Maximum bandwidth value.
To open bandwidth management, select System Management > Bandwidth Management in the navigation tree.
