conform-action transmit violate-action drop
police-two-rate
Use the police-two-rate command to implement a two-rate Three Color
Market (trTCM) per RFC 2698. A trTCM meters a traffic stream and colors
packets according to four parameters:
Committed Information Rate (CIR)
Committed Burst Size (CBS)
Peak Information Rate (PIR)
Peak Burst Size (PBS)
A packet is colored red if it exceeds the PIR, yellow if it exceeds the CIR, and
green if it does not exceed either. A trTCM is useful when a peak rate needs to
be enforced separately from a committed rate.
