Configuring Color-Aware Policing
Value
cs7
default
ef
After you apply color-aware policing, all matching packets in the device are policed according to the
specifications of the color-aware policer.
To configure color-aware policing:
1. Create the class map. For information about configuring class maps, see "Configuring Classification."
2. Create a policy map. For information about policy maps, see this chapter and "Using Modular QoS CLI."
3. Configure the color-aware class map as described in this section.
4. Apply the service policy to the interfaces. For information about attaching policies to interfaces, see
"Using Modular QoS CLI."
Note The rates specified in the shared policer are shared by the number of interfaces to which you apply the service
policy. Each interface does not have its own dedicated rate as specified in the shared policer.

message:
Warning: Configuring match for any DSCP
values in this class-map will make
ALL policers in the system color-aware
for those DSCP values.
Specifies the DSCP value to match for
color-aware policers. See the table above for a
list of valid values.
Creates or accesses the policy map named
