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.

8.1.3.11 police
Command:police <rate-kbps> <burst-kbyte> [exceed-action {drop |
policed-dscp-transmit}]
no police <rate-kbps> <burst-kbyte> [exceed-action {drop |
policed-dscp-transmit}]
Function:
Configures a policy to a classified traffic; the “no police <rate-kbps>
<burst-kbyte> [exceed-action {drop | policed-dscp-transmit}] ” command deletes the
specified policy.
Parameters: <rate-kbps> is the average baud rate (kb/s) of classified traffic, ranging
from 1,000 to 10,000,000; exceed-action drop means drop packets when specified
speed is exceeded; exceed-action policed-dscp-transmit specifies to mark down
packet DSCP value according to policed-dscp mapping when specified speed is
exceeded.
Default: There is no policy by default.
Command mode: Policy class map configuration Mode
Usage Guide: The ranges of <rate-kbps> and <burst-kbyte> are quite large, if the
setting exceeds the actual speed of the port, the policy map applying this policy will not
bind to switch ports.
Example: Setting the bandwidth for packets that matching c1 class rule to 20 Mbps, with
a burst value of 2 MB, all packets exceed this bandwidth setting will be dropped.
