speed (for 1000/10000/auto interfaces)

Set the speed for 1000/10000 Base-T Ethernet interfaces. Set both sides of a link to the same speed (1000/10000) or to auto or the link may not come up.

Syntax

speed {1000 | 10000 | auto}

To return to the default setting, use the no speed {1000 | 10000 | auto} command.

Parameters

1000	Enter the keyword `1000` to set the interface’s speed to 1000 Mb/s.
10000	Enter the keyword `10000` to set the interface’s speed to 10000 Mb/s. Auto-negotiation is enabled. For more information, refer to `negotiation auto`.
auto	Enter the keyword `auto` to set the interface to auto-negotiate its speed. Auto-negotiation is enabled. For more information, refer to `negotiation auto`.

Defaults

Usage Information

This command is found on the 1000/10000 Base-T Ethernet interfaces.

When you enable auto, the system performs an automatic discovery to determine the optics installed and configure the appropriate speed.

When you configure a speed for the 1000/10000 interface, confirm the negotiation auto command setting. Both sides of the link must have auto-negotiation either enabled or disabled. For speed settings of 1000 or auto, the software sets the link to auto-negotiation and you cannot change that setting.

Related Commands

duplex (1000/10000 Interfaces) — configures duplex mode on physical interfaces with the speed set to 10/100.

negotiation auto — enables or disables auto-negotiation on an interface.

If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP+ port or 1 Gigabit SFP port. You can use the speed command to enable the required speed.
