Synopsis

autobaud [fast]
no autobaud

Configures

Automatic baud rate detection

Default

Disabled

Description

The autobaud command configures a line to select the incoming baud rate automatically. The baud rate must be between 300 and 115200. There are two limitations to this command:

  • Autobaud cannot be used on a connection at rates higher than 19,200 baud when the parity bit is set.

  • This command cannot be used on outgoing connections.

The optional fast keyword detects the baud rate with exactly three carriage returns.

Many routers do not support the higher baud rates.

Example

The following commands enable automatic baud rate detection on line 3:

Router(config)#line 3
Router(config-line)#autobaud

To disable autobaud and to return to the default, use the no form of this command:

Router(config)#line 3
Router(config-line)#no autobaud
