Figure 6-7. Configuring a DSCP Policy for Global TCP/UDP Port Classifiers
The switch applies the DSCP policies in Figure 6-7 to IP packets with the
specified TCP/UDP port applications that are received in the switch. The
switch manages the packets as follows:
■ Overwrites the original DSCPs in the selected packets with the new
DSCPs specified in the above policies.
■ Assigns the 802.1p priorities in the above policies to the selected packets.
