Command Line Interface

Default Setting

Auto-negotiation is enabled by default.

When auto-negotiation is disabled, the default speed-duplex setting is 100half for 100BASE-TX ports and 1000full for Gigabit Ethernet ports.

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

To force operation to the speed and duplex mode specified in a speed-duplexcommand, use the no negotiation command to disable auto-negotiation on the selected interface.

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

Example

The following example configures port 5 to 100 Mbps, half-duplex operation.

Console(config)#interface ethernet 1/5

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

Console(config-if)#no negotiation

Console(config-if)#
