<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:

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 from the default 0 8 16 24 32 40 48
56 to 0 1 2 3 4 5 6 7.
