Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

To force operation to the speed and duplex mode specified in a speed- duplex command, use the no negotiation command to disable auto- negotiation on the selected interface. However, note that auto-negotiation cannot be disabled on the down-link ports. These ports are fixed at 1000 Mbit/sec, full duplex.

When using the negotiation command to enable auto-negotiation, the optimal settings will be determined by the capabilities command. To set the speed or duplex mode under auto-negotiation, the required mode must be specified in the capabilities list for an interface.

Example

The following example configures port NETP5 to 100 Mbit/sec, half-duplex operation.

Console(config)#interface ethernet NETP5

Console(config-if)#no negotiation

Console(config-if)#speed-duplex 100half

Console(config-if)#
