Overview of Rate Metering (Policing) (CLI)
The IP-20 switching fabric supports hierarchical policing on the logical
interface level. You can define up to 250 rate meter (policer) profiles.
Note:
Policing on the service point level, and the service point and
CoS level, is planned for future release.
The IP-20's policer mechanism is based on a dual leaky bucket mechanism
(TrTCM). The policers can change a frame’s color and CoS settings based on
CIR/EIR + CBS/EBS, which makes the policer mechanism a key tool for
implementing bandwidth profiles and enabling operators to meet strict SLA
requirements.
The output of the policers is a suggested color for the inspected frame. Based
on this color, the queue management mechanism decides whether to drop the
frame or to pass it to the queue.
