User Guidelines
Policing uses a token bucket algorithm. CIR represents the speed with which
the token is removed from the bucket. CBS represents the depth of the
bucket.
Example
The following example defines a policer for classified traffic. When the traffic
rate exceeds 124,000 kbps or the normal burst size exceeds 9600 bytes, the
packet is dropped. The class is called Class1 and is in a policy map called
Policy1.
