transmit-rate

Syntax

transmit-rate (rate | percent percentage | remainder) <exact | rate-limit>;

Hierarchy Level

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

Release Information

Statement introduced before JUNOS Release 7.4.

rate-limit option introduced in JUNOS Release 8.3. Applied to the Multiservices PICs in JUNOS Release 9.4.

Description

Specify the transmit rate or percentage for a scheduler.

Default

If you do not include this statement, the default scheduler transmission rate and buffer size percentages for queues 0 through 7 are 95, 0, 0, 5, 0, 0, 0, and 0 percent.

Options

exact—(Optional) Enforce the exact transmission rate. Under sustained congestion, a rate-controlled queue that goes into negative credit fills up and eventually drops packets. This value should never exceed the rate-controlled amount.

percent percentage—Percentage of transmission capacity. A percentage of zero drops all packets in the queue.

Range: 0 through 100 percent

rate—Transmission rate, in 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 160,000,000,000 bps

rate-limit—(Optional) Limit the transmission rate to the rate-controlled amount. In contrast to the exact option, the scheduler with the rate-limit option shares unused bandwidth above the rate-controlled amount.

remainder—Use remaining rate available.
