Adding Color-Aware Policing Attribute
Policing in the DiffServ feature uses either “color blind” or “color aware” mode. Color blind
mode ignores the coloration (marking) of the incoming packet. Color aware mode takes into
consideration the current packet marking when determining the policing outcome. An
auxiliary traffic class is used in conjunction with the policing definition to specify a value for
one of the DSCP or IP Precedence fields designating the incoming color value to be used as
the conforming color.
The following commands show how to add a color aware policing attribute to the finance_dept
class.
1. Add a new class to serve as the auxiliary traffic class. The match condition for the class
must be either IP Precedence or IP DSCP. In this example, the match condition is IP Prece-
dence with a value of 2.
class-map match-all color_class
match ip precedence 2
exit
2. Before adding the color aware mode, you must configure policing for the finance_dept
class.
The following commands first configure simple policing with a conforming data rate of
10000 Kbps, a burst size of 100, a conform action of send, and a violate action of drop.
After the policing is configured, the color aware attribute is configured. The color-aware
attribute cannot be configured before policing.
