shaping-rate (Applying to an Interface)

Syntax

Hierarchy Level

Release Information

Statement introduced in Release 8.5 of Junos OS.

Description

For logical interfaces on which you configure packet scheduling, configure traffic shaping by specifying the amount of bandwidth to be allocated to the logical interface.

Note: The shaping-rate statement cannot be applied to a physical interface on J Series routing platforms.

Logical and physical interface traffic shaping is mutually exclusive. This means you can include the shaping-rate statement at the [edit class-of-service interfaces interface interface-name] hierarchy level or the [edit class-of-service interfaces interface interface-name unit logical-unit-number] hierarchy level, but not both.

Alternatively, you can configure a shaping rate for a logical interface and oversubscribe the physical interface by including the shaping-rate statement at the [edit class-of-service traffic-control-profiles] hierarchy level. With this configuration approach, you can independently control the delay-buffer rate. For more information on the delay-buffer rate, see the Junos OS Class of Service Configuration Guide for Security Devices.

Default

If you do not include this statement at the [edit class-of-service interfaces interface interface-name unit logical-unit-number] hierarchy level, the default logical interface bandwidth is the average of unused bandwidth for the number of logical interfaces that require default bandwidth treatment. If you do not include this statement at the [edit class-of-service interfaces interface interface-name] hierarchy level, the default physical interface bandwidth is the average of unused bandwidth for the number of physical interfaces that require default bandwidth treatment.

Options

rate—Peak rate, in bits per second (bps). You can specify a value in bits per second either as a complete decimal number or as a decimal number followed by the abbreviation k (1000), m (1,000,000), or g (1,000,000,000).

Range: For logical interfaces, 1000 through 32,000,000,000 bps.

For physical interfaces, 1000 through 160,000,000,000 bps.
