Quality of Service (QoS)
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay, and the net-
working methods used to control the use of bandwidth. Without QoS, all traffic date is equally likely to be
dropped when the network is congested. This can cause a reduction in network performance and mark the net-
work inadequate for time-critical application such as video-on-demand.
Click on QoS under Advanced on the main menu to reach the QoS advanced configuration page.

QoS (Quality of Service) is used to decide which devices can get priorities to pass though the Model 3202 once
the bandwidth is exhausted or fully saturated.
There are three types of QoS priority modes: Port Based Priority, VLAN Tag Priority and IP DSCP Priority.
You can also disable the QoS function.
