DiffServ Code Point

This chapter shows you how to set up Diffserv Code Point (DSCP) on each port and how to convert DSCP values to IEEE 802.1p values.

25.1 DiffServ Overview

DiffServ Code Point (DSCP) is a field used for packet classification on DiffServ networks. The higher the value, the higher the priority. Lower-priority packets may be dropped if the total traffic exceeds the capacity of the network.

25.2 Enable DiffServ

Click IP Application, DiffServ in the navigation panel to display the screen as shown.
