<
dscp1...dscp8>
are the 8 DSCP value corresponding to the 0 to 7 CoS value, each
DSCP value is delimited with space, ranging from 0 to 63;
dscp-cos <
dscp-list>
to
<
cos>
defines the mapping from DSCP to CoS value,
<
dscp-list>
is a list of DSCP
value consisting of up to 8 DSCP values,
<
cos>
are the CoS values corresponding to
the DSCP values in the list
；
dscp-mutation
<dscp-mutation-name> <in-dscp>
to
<
out-dscp>
defines the mapping from DSCP to DSCP mutation,
<dscp-mutation-name>
is the name for mutation mapping,
<in-dscp>
stand
for
incoming DSCP values, up to 8 values are supported, each DSCP value is delimited
with space, ranging from 0 to 63,
<
out-dscp>
is the sole outgoing
DSCP value, the 8
values defined in incoming DSCP will be converted to outgoing DSCP values;
ip-prec-dscp <
dscp1...dscp8>
defines the conversion from IP precedence to DSCP
value,
<
dscp1...dscp8>
are 8 DSCP values corresponding to IP precedence 0 to 7,
each DSCP value is delimited with space, ranging from 0 to 63;
policed-dscp
<
dscp-list>
to <
mark-down-dscp>
defines DSCP
mark down
mapping, where
<
dscp-list>
is a list of DSCP values containing up to 8 DSCP values,
<
mark-down-dscp>
are DSCP value after
mark down
.
Default:

dscp-mutation and policed-dscp are not configured by default
Command mode:
Global Mode
Usage Guide:
In
police
command, classified packet traffic can be set to mark down if exceed
specified average speed or burst value,
policed-dscp <
dscp-list>
to
<
mark-down-dscp>
can mark down the DSCP values of those packets to new DSCP
values.
Example:
Setting the
CoS-to-DSCP
mapping value to the default 0 8 16 24 32 40 48 56 to 0 1 2 3 4
5 6 7.
Switch(Config)#mls qos map cos-dscp 0 1 2 3 4 5 6 7

Example
Scenario 1:
Enable QoS function, change the queue out weight of Ethernet port 1/1 to 1:1:2:2:4:4:8:8, and set
