Policer Bandwidth and Burst-Size Limits

Table 5: Policer Bandwidth Limits and Burst-Size Limits

Policer Type
Single-Rate Two-Color Policer
Defines a single rate limit: a bandwidth limit and an
allowed burst size for conforming traffic.
For a single-rate two-color policer only, you can
specify the bandwidth limit as a percentage value
from 1 through 100 instead of as an absolute number
of bits per second. The effective bandwidth limit is
calculated as a percentage of either the physical
interface media rate or the logical interface
configured shaping rate.
Single-Rate Three-Color Policer
Defines a single rate limit: a bandwidth limit and an
allowed burst size for conforming traffic.
Also defines a second, larger burst size. This second
burst size is used to differentiate between two
categories of nonconforming traffic (yellow or red).

Table 5 on page 17 lists each of the Junos OS policer types supported. For each policer
type, the table summarizes the bandwidth limits and burst-size limits used to rate-limit
traffic.
