DSCP-based Priority Setting

The Differentiated Services Code Point (DSCP) is a six-bit field in the IP header, allowing coding for up to 64

different forwarding behaviors. The DSCP replaces the ToS bits, but it retains backward compatibility with the

three precedence bits so that non-DSCP-compliant, ToS-enabled devices will not conflict with the DSCP

mapping. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding.

Note that all the DSCP values that are not specified are mapped to priority value 0.

Web Smart switch interface

To configure port-level DSCP remarking:

1. Click Configuration, QoS, DSCP-based Priority.

2. Map one or more DSCP values to a priority value.

3. Click Apply.
