Policer Color-Marking And Actions; Table 6: Implicit And Configurable Policer Actions Based On Color Marking - Juniper EX9200 Features Manual

Traffic Policers Feature Guide for EX9200 Switches
Table 5: Policer Bandwidth Limits and Burst-Size Limits (continued)
Policer Type
Two-Rate Three-Color Policer
Defines a committed rate limit: a bandwidth limit and
an allowed burst size for conforming traffic.
Also defines a peak rate limit: a second, larger burst
size and a second, higher bandwidth limit. These
additional rate-limit components are used to
differentiate between two categories of
nonconforming traffic (yellow or red).

Policer Color-Marking and Actions on page 18
Determining Proper Burst Size for Traffic Policers on page 30
Table 6 on page 18 lists each of the Junos OS policer types supported. For each policer
type, the table summarizes the color-marking criteria used to categorize a traffic flow
and, for each color, the actions taken on packets in that type of traffic flow.
