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.
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 3-160.
