The following example globally enables DSCP Priority service on the switch, maps DSCP value 0 to CoS
value 1 (on port 1), and then displays the DSCP Priority settings.

Console(config-if)#
map ip dscp 1 cos 0
Console(config-if)#

Mapping specific values for IP DSCP is implemented as an interface configuration command, but any
changes will apply to the all interfaces on the switch.
11.5.3 Mapping IP Port Priority
You can also map network applications to Class of Service values based on the IP port number (For
example, TCP/UDP port number) in the frame header. Some of the more common TCP service ports
include: HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.
