Configuring Ethernet Interfaces

DETAILED STEPS

	Command or Action
Step 1	configure terminal
	Example:
	Switch# configure terminal
Step 2	interface interface-id
	Example:
	Switch(config)# interface
	gigabitethernet1/0/3
Step 3	speed {10 100 1000 auto [10 100
	1000] nonegotiate}
	Example:
	Switch(config-if)# speed 10

Step 4 duplex {auto full half}

Example:

Switch(config-if)# duplex half

Step 5 end

Example:

Switch(config-if)# end

Purpose

Enters global configuration mode.

Specifies the physical interface to be configured, and enter interface configuration mode.

This command is not available on a 10-Gigabit Ethernet interface.

Enter the appropriate speed parameter for the interface:

•Enter 10, 100, or 1000 to set a specific speed for the interface. The 1000 keyword is available only for 10/100/1000 Mb/s ports.

•Enter auto to enable the interface to autonegotiate speed with the connected device. If you use the 10, 100, or the 1000 keywords with the auto keyword, the port autonegotiates only at the specified speeds.

•The nonegotiate keyword is available only for SFP module ports. SFP module ports operate only at 1000 Mb/s but can be configured to not negotiate if connected to a device that does not support autonegotiation.

This command is not available on a 10-Gigabit Ethernet interface.

Enter the duplex parameter for the interface.

Enable half-duplex mode (for interfaces operating only at 10 or 100 Mb/s). You cannot configure half-duplex mode for interfaces operating at 1000 Mb/s.

You can configure the duplex setting when the speed is set to auto.

Returns to privileged EXEC mode.

Step 6 show interfaces interface-id Displays the interface speed and duplex mode configuration.
