SMC Networks SMC6752AL2 manual 179, Mapping IP Port Priority

CLASS OF SERVICE CONFIGURATION

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	4-233
Console(config)#interface ethernet 1/1				4-145
Console(config-if)#map ip dscp 1 cos 0				4-233
Console(config-if)#end
Console#show map ip			dscp ethernet 1/1	4-237
DSCP mapping status: enabled
Port	DSCP COS
--------- ---- ---
Eth 1/ 1	0	0
Eth 1/ 1	1	0
Eth 1/ 1	2	0
. Eth 1/ 1	3	0
.
.
Eth 1/ 1	61	0
Eth 1/ 1	62	0
Eth 1/ 1	63	0
Console#

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.

Command Attributes

•IP Port Priority Status – Enables or disables the IP port priority.

•IP Port Priority Table – Shows the IP port to CoS map.

•IP Port Number (TCP/UDP) – Set a new IP port number.

•Class of Service Value – Sets a CoS value for a new IP port. Note that “0” represents low priority and “7” represent high priority.
