User Guidelines
Only one style of police command (simple or two-rate) is allowed for a given
class instance in a particular policy. The
conform-color command can be used
to pre-color packets prior to policing. Packets pre-colored red are not re-
colored by the policer.
Example
The following example configures a single rate ingress meter with packets
received at a rate below 1000 Kbps and 4096 byte burst size are transmitted
and packets above that rate are dropped. The transmitted packets are colored
green should the operator desire to configure a WRED drop policy.
console(config-policy-classmap)#police-simple 1000 64
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)
