# speed

#### Syntax

For console sessions:

speed baudRate

no speed

For Ethernet interfaces on line modules:

speed speedValue

no speed

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

When used from Line Configuration mode, sets the speed for the current and all new console sessions immediately. The no version reverts to the default value, 9600 bps.

When used from Interface Configuration mode, specifies the line speed for an Ethernet interface. This command works with the duplex command; if you set or accept the automatically negotiate setting for either duplex mode or speed, the router negotiates both parameters with the remote device. The no version specifies the default, automatically negotiate or 100 Mbps (FE-8 SFP I/O module only). This command is not available for the Ethernet interface on the SRP module.

#### Options

- baudRate—Terminal speed for the current console session; one of the following values: 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200
- speedValue—Line speed; one of the following values:
  - automatically negotiate—Specifies that the router negotiates the line speed with the remote device; not valid for the FE-8 SFP I/O module
  - 10—Specifies that the router uses a line speed of 10 Mbps on a Fast Ethernet interface; not valid for Gigabit Ethernet interfaces or the FE-8 SFP I/O module
  - 100—Specifies that the router uses a line speed of 100 Mbps on a Fast Ethernet interface; not valid for Gigabit Ethernet interfaces
  - 1000—Specifies that the router uses a line speed of 1000 Mbps on a Gigabit Ethernet interface; not valid for Fast Ethernet interfaces

#### Mode

Interface Configuration, Line Configuration
