shaping-rate (Limiting Excess Bandwidth Usage)

Syntax

shaping-rate (percent percentage | rate);

Hierarchy Level

[edit class-of-service schedulers scheduler-name]

Release Information

Statement introduced before JUNOS Release 7.4.

Description

For J Series routers only, define a limit on excess bandwidth usage.

The transmit-rate statement at the [edit class-of-service schedulers scheduler-name hierarchy level configures the minimum bandwidth allocated to a queue. The transmission bandwidth can be configured as an exact value or allowed to exceed the configured rate if additional bandwidth is available from other queues. For J Series routers only, you limit the excess bandwidth usage with this statement.

You should configure the shaping rate as an absolute maximum usage and not the additional usage beyond the configured transmit rate.

Default

If you do not include this statement, the default shaping rate is 100 percent, which is the same as no shaping at all.

Options

percent percentage—Shaping rate as a percentage of the available interface bandwidth.

Range: 0 through 100 percent

rate—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: 3200 through 32,000,000,000 bps

Usage Guidelines

See Applying Scheduler Maps Overview.

Required Privilege Level

interface—To view this statement in the configuration.
