buffer-size

Syntax

buffer-size (percent percentage | remainder | temporal microseconds);

Hierarchy Level

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

Release Information

Statement introduced before JUNOS Release 7.4.

Description

Specify buffer size.

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

percent percentage—Buffer size as a percentage of total buffer.

remainder—Remaining buffer available.

temporal microseconds—Buffer size as a temporal value. The queuing algorithm starts dropping packets when it queues more than a computed number of bytes. This maximum is computed by multiplying the logical interface speed by the configured temporal value.

Range: The ranges vary by platform as follows:
  • For M320 and T Series routers with Type 1 and Type 2 FPCs: 1 through 80,000 microseconds.
  • For M320 and T Series routers with Type 3 FPCs: 1 through 50,000 microseconds.
  • For M7i, M10i, M5, and M10 routers: 1 through 100,000 microseconds.
  • For other M Series routers: 1 through 200,000 microseconds.
  • For IQ PICs on M320 and T Series routers: 1 through 50,000 microseconds.
  • For IQ PICs on other M Series routers: 1 through 100,000 microseconds.

Usage Guidelines
