Logical Interface (Aggregate) Policer Overview
A
logical interface policer
—also called an
aggregate policer
—is a two-color or three-color
policer that defines traffic rate limiting that you can apply to input or output traffic for
multiple protocol families on the same logical interface without creating multiple
instances of the policer.
To configure a single-rate two-color logical interface policer, include the
logical-interface-policer
statement at one of the following hierarchy levels:
•
[edit firewall
policer-name
]
•
[edit logical-systems
logical-system-name
firewall
policer-name
]
To configure a single-rate or two-rate three-color logical interface policer, include the
logical-interface-policer
statement at one of the following hierarchy levels:
•
[edit firewall
name
]
•
[edit logical-systems
logical-system-name
firewall
name
]
NOTE:
A three-color policer can be applied to Layer 2 traffic as a logical
interface policer only. You cannot apply a three-color policer to Layer 2 traffic
as a physical interface policer (through a firewall filter).
You apply a logical interface policer to Layer 3 traffic directly to the interface configuration
at the logical unit level (to rate-limit all traffic types, regardless of the protocol family)
or at the protocol family level (to rate-limit traffic of a specific protocol family). It is OK
to reference a logical interface policer from a stateless firewall filter term and then apply
the filter to a logical interface.
