speed

Set the speed of an interface.

Syntax
speed [ 10 | 100 ]
 
no speed
 
Prerequisites

Must be in interface configuration mode (config-if), which requires privileged-level access.

Occurrence

Use once per interface.

Default

Auto

Description

The speed command with no keyword sets the speed to auto.

Both speed and duplex of an interface can be configured, but they are dependent on each other. If any one of them is set to auto, then both will be implemented as auto regardless of the setting of the other.

Changing either speed or duplex will bring the interface down and back up and you will lose Telnet or SSH connectivity. Changes to these modes should be done from a serial port connection.

See the duplex command.
