Examples This example shows how to set the interface speed to 100 Mbps on the Fast Ethernet interface 5/4:
Switch(config)# interface fastethernet 5/4
Switch(config-if)# speed 100
This example shows how to allow Fast Ethernet interface 5/4 to autonegotiate the speed and duplex
mode:
Switch(config)# interface fastethernet 5/4
Switch(config-if)# speed auto
Note The speed auto 10 100 command is similar to the speed auto command on a Fast Ethernet interface.
This example shows how to limit the interface speed to 10 and 100 Mbps on the Gigabit Ethernet
interface 1/1 in auto-negotiation mode:
Switch(config)# interface gigabitethernet 1/1
Switch(config-if)# speed auto 10 100
This example shows how to limit the speed negotiation to 100 Mbps on the Gigabit Ethernet
interface 1/1:
Switch(config)# interface gigabitethernet 1/1
