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
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.
