Release Information

Statement introduced in JUNOS Release 7.6.


For Gigabit Ethernet IQ, Channelized IQ PICs, and AS PIC FRF.16 LSQ interfaces only, base the delay-buffer calculation on a delay-buffer rate.


If you do not include this statement, the delay-buffer calculation is based on the guaranteed rate if one is configured, or the shaping rate if no guaranteed rate is configured. For more information, see Oversubscribing Interface Bandwidth.


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

Range: 1 through 100 percent

rate—For IQ and IQ2 interfaces, delay-buffer 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

See Oversubscribing Interface Bandwidth, Providing a Guaranteed Minimum Rate, and Configuring Traffic Control Profiles for Shared Scheduling and Shaping.

Required Privilege Level

interface—To view this statement in the configuration.

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