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.
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 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 3-155.
Command Usage
You must configure an ACL mask before you can map CoS values to the
rule.
