SMC Networks SMC6224M manual 180, Mapping IP Port Priority

CONFIGURING THE SWITCH

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	4-231
Console(config)#interface ethernet 1/1				4-143
Console(config-if)#map ip dscp 1 cos 0				4-231
Console(config-if)#end
Console#show map ip			dscp ethernet 1/1	4-235
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
.
.	61	0
Eth 1/ 1
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.

Note: IP Port Priority settings apply to all interfaces.
