policer (Configuring)


Hierarchy Level


Configure policer rate limits and actions. When included at the [edit firewall] hierarchy level, the policer statement creates a template, and you do not have to configure a policer individually for every firewall filter or interface. To activate a policer, you must include the policer-action modifier in the then statement in a firewall filter term or on an interface.

You can configure the policer in static firewall filters or dynamic firewall filters in a dynamic client profile or a dynamic service profile.

Except for EX8200 switches, each policer that you configure includes an implicit counter. To obtain term-specific packet counts, configure a policer for each term in the filter that requires policing. For EX8200 switches, configure a policer and associate it with a global management counter using the counter option.



One or more actions to take:

  • discard—Discard traffic that exceeds the rate limits.

  • forwarding-class class-name—Specify the particular forwarding class.

  • loss-priority—Set the packet loss priority (PLP) to low, medium-low, medium-high, or high.


Name that identifies the policer. The name can contain letters, numbers, and hyphens (-), and can be up to 255 characters long. To include spaces in the name, enclose it in quotation marks (“ ”). Policer names cannot begin with an underscore in the form __.*.


Actions to take on matching packets.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
