<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 listdscp-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.

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