Release Information

Statement introduced in JUNOS Release 9.2.

The $junos-cos-shaping-rate variable added in JUNOS Release 9.4.

Description

For EQ DPC 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).

Default

The default behavior depends on various factors.

Options

rate—For EQ DPC interfaces, either the peak rate in bits per second (bps) or the $junos-cos-shaping-rate JUNOS predefined variable. The variable is replaced with the shaping rate obtained from the RADIUS server when a subscriber authenticates over the subscriber interface to which the subscriber access dynamic profile is attached.

When specifying the actual value in bits per second, you can specify the value as a complete decimal number or as a decimal number followed by the abbreviation k (1000), (1,000,000), or g (1,000,000,000).

Range: 1000 through 160,000,000,000 bps
