CLI – The following example globally enables IP Port Priority service on the switch,
maps HTTP traffic (on port 1) to CoS value 0, and then displays the IP Port Priority
settings.
* 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 3-140.
Command Usage
You must configure an ACL mask before you can map CoS values to the rule.
