speed

Use the speed interface configuration command to specify the speed of a 10/100 Mbps or

10/100/1000 Mbps port. Use the no or default form of this command to return the port to its default

For speed configurations restrictions on small form-factor pluggable (SFP) module ports, see the "Usage

Guidelines" section.

You cannot configure the speed on small form-factor pluggable (SFP) module ports, but you can

configure the speed to not negotiate (nonegotiate) if they are connected to a device that does not support

autonegotiation. See "Usage Guidelines" for exceptions when a 1000BASE-T SFP module is in the SFP

module slot.

Syntax Description

The default is auto.

Usage Guidelines

You can configure the Fast Ethernet port speed as either 10 or 100 Mbps.

You can configure the Gigabit Ethernet port speed as 10, 100, or 1000 Mbps.

When a 1000BASE-T SFP module is in the SFP module slot, you can configure the speed as 10, 100,

1000, or auto but not to nonegotiate.

speed {10 | 100 | 1000 | auto [10 | 100 | 1000] | nonegotiate}

Port runs at 10 Mbps.

Port runs at 100 Mbps.

Port runs at 1000 Mbps. This option is valid and visible only on 10/100/1000

Port automatically detects the speed it should run at based on the port at the other

end of the link. If you use the 10, 100, or 1000 keywords with the auto keyword, the

port only autonegotiates at the specified speeds.

Autonegotiation is disabled, and the port runs at 1000 Mbps. (The 1000BASE-T SFP

does not support the nonegotiate keyword.)
