Release Information
Statement introduced in Junos OS Release 9.2.
The $junos-cos-shaping-rate variable for traffic-control profiles introduced in Junos OS Release 9.4.
The $junos-cos-scheduler-shaping-rate variable for schedulers introduced in Junos OS Release 10.2.
Option burst-size introduced in Junos OS Release 11.4.
Description
Configure a shaping rate for a logical interface or a scheduler. The sum of the shaping rates for all logical interfaces on the physical interface can exceed the physical interface bandwidth. This practice is known as oversubscription of the peak information rate (PIR).
Options
rate—Peak rate in bits per second (bps). You can specify the value 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: 1000 through 160,000,000,000 bps
predefined-variable—One of the following Junos predefined variables. The variable is replaced with a value obtained from the RADIUS server when a subscriber authenticates over the interface to which the dynamic profile is attached.
- $junos-cos-shaping-rate—Variable for the shaping rate that is specified for the logical interface. Use this variable at the [edit dynamic-profiles profile-name class-of-service traffic-control-profiles profile-name] hierarchy level.
- $junos-cos-scheduler-shaping-rate—Variable for the shaping rate that is specified for a scheduler. Use this variable at the [edit dynamic-profiles profile-name class-of-service schedulers scheduler-name] hierarchy level.
burst-size bytes—(Optional) Maximum burst size, in bytes.
Range: 0 through 1,000,000,000
$junos-cos-shaping-rate-burst—(Optional) Variable for the burst-size that is specified for the shaping rate. Use this variable at the [edit dynamic-profiles profile-name class-of-service traffic-control-profile] hierarchy level.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
