Release Information

Statement introduced in JUNOS Release 7.6.


For Gigabit Ethernet IQ, Channelized IQ PICs, and AS PIC FRF.16 LSQ interfaces only, configure a shaping rate for a logical interface. 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).


The default behavior depends on various factors. For more information, see Oversubscribing Interface Bandwidth.


percent percentage—For LSQ interfaces, shaping rate as a percentage of the available interface bandwidth.

Range: 1 through 100 percent

rate—For IQ and IQ2 interfaces, 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: 1000 through 160,000,000,000 bps

Usage Guidelines
