Layer 3/4 Priority Settings

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.
*
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.
