CLI
– 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.
Note:
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.
Mapping IP Port Priority
You can also map network applications to Class of Service values based on
the IP port number (i.e., 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.
