Element Description
Committed Information Rate
(CIR)
Enter the CIR to be used for the policy in kilobits per second. When
the traffic rate reaches the CIR, excess traffic is dropped or
remarked.
Normal Burst Size (BC) Optional. Enter the normal burst size in kilobits per second. The
normal burst size determines how large traffic bursts can be before
some traffic exceeds the CIR.
Excess Burst Size (BE) Optional. Enter the excess burst size in kilobits per second. The
excess burst size determines how large traffic bursts can be before
all traffic exceeds the rate limit. Traffic that falls between the
normal burst size and the excess burst size exceeds the rate limit
with a probability that increases as the burst size increases.
