SMC Networks SMC6752AL2 manual 181, Mapping CoS Values to ACLs, Egress Queue Priority Mapping

CLASS OF SERVICE CONFIGURATION

CLI – The following example globally enables IP Port Priority service on the switch, maps HTTP traffic on port 5 to CoS value 0, and then displays all the IP Port Priority settings for that port.

Console(config)#map		ip port	4-229
Console(config)#interface ethernet 1/5
Console(config-if)#map ip port 80 cos 0			4-230
Console(config-if)#end
Console#show map ip		port ethernet 1/5	4-230
TCP port mapping status: enabled
Port	Port no. COS
--------- --------		---
Eth 1/ 5	80	0
Console#

Note: Mapping specific values for IP Port Priority is implemented as an interface configuration command, but any changes will apply to the all interfaces on the switch.

Mapping CoS Values to ACLs

Use the ACL CoS Mapping page to set the output queue for packets matching an ACL rule as shown in the following table. Note that the specified CoS value is only used to map the matching packet to an output queue; it is not written to the packet itself. For information on mapping the CoS values to output queues, see page 3-169.
