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 a time-critical application such as video-on-demand.
The qos command menu lists commands for managing traffic. Move the cursor " >>" to qos in the setup menu
and press Enter. The following menu displays:
