Class of Service Configuration 3

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.

Console(config)#map

ip dscp

4-189

Console(config)#interface ethernet 1/1

4-116

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

4-190

Console(config-if)#end

 

Console#show map ip

dscp ethernet 1/1

*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.

Command Attributes
