speed

Function

The speed command sets the rate for an Ethernet interface in non-auto negotiation mode.

The undo speed command restores the default rate of an Ethernet interface in non-auto negotiation mode.

By default, an Ethernet interface works at its highest rate when it works in non-auto negotiation mode.

Format

speed { 10 | 100 | 1000 | 2500 | 5000 | 10000 }

Parameters

Parameter	Description	Value
10	Indicates that the interface works at 10 Mbit/s.	-
100	Indicates that the interface works at 100 Mbit/s.	-
1000	Indicates that the interface works at 1000 Mbit/s. NOTE: FE interfaces do not support this parameter.	-
2500	Sets the auto-negotiation rate of an Ethernet electrical interface to 2500 Mbit/s. NOTE: Only MultiGE interfaces support this parameter.	-
5000	Sets the auto-negotiation rate of an Ethernet electrical interface to 5000 Mbit/s. NOTE: Only MultiGE interfaces support this parameter.	-
10000	Sets the auto-negotiation rate of an Ethernet electrical interface to 10000 Mbit/s. NOTE: Only MultiGE interfaces support this parameter. Only MultiGE interfaces on the S5732-H24UM2CC, S5732-H48UM2CC, S6720-32C-SI-AC, S6720-32C-SI-DC, S6720-32C-PWH-SI-AC, S6720-52X-PWH-SI, S6720-56C-PWH-SI-AC, S6720-56C-PWH-SI, and S6720-32C-PWH-SI support this parameter.	-

Usage Guidelines

Usage Scenario

In non-auto negotiation mode, if interfaces on two connected devices work at different rates, use the speed command to change the rates of the interfaces to be the same so that the two devices can communicate.

Precautions

If the remote interface does not support the auto negotiation mode, run the undo negotiation auto command on the local interface to configure the interface to work in non-auto negotiation mode. You can then change the rate of the local interface to be the same as the rate of the remote interface to ensure proper communication.

Example

# Configure GE0/0/1 to work at 100 Mbit/s in non-auto negotiation mode.
