Release Information

Statement introduced in Junos OS Release 7.6.

Option burst-size introduced for Enhanced Queuing (EQ) DPCs in Junos OS Release 9.4.

Option burst-size introduced for MPC/MIC modules in Junos OS Release 11.4.

Option burst-size introduced for IQ2 and IQ2E interfaces in Junos OS Release 12.3

Description

For Gigabit Ethernet IQ, Channelized IQ PICs, AS PIC FRF.16 LSQ interfaces, and EQ DPCs only, configure a guaranteed minimum rate. You can also configure an optional burst size for a logical interface on EQ DPCs and on IQ2 and IQ2E PICs. This can help to ensure that higher priority services do not starve lower priority services.

Default

If you do not include this statement and you do not include the delay-buffer-rate statement, the logical interface receives a minimal delay-buffer rate and minimal bandwidth equal to 2 MTU-sized packets.

Options

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

Range: 1 through 100 percent

rate—For IQ and IQ2 interfaces, guaranteed 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

burst-size bytes—(Optional) Maximum burst size, in bytes.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
