Enters global configuration mode. Step 3 Example: Router# configure terminal interface fastethernet interface-id Step 4 Example: Router(config)# interface fastethernet 0/1/0 speed {10 | 100 | 1000 [negotiate] | auto [speed-list]} Example: Router(config-if)# speed 100 Selects the interface to be configured and enters interface configuration mode. • Enter the interface number. Configures the speed for the interface. • Enter the desired speed. Note If you set the interface speed to auto on a 10/100-Mbps Ethernet interface, both speed and duplex are automatically negotiated. Configuring the Interface Duplex Mode Follow the steps below to set the duplex mode of a Fast Ethernet interface. When configuring an interface duplex mode, note these guidelines: • If both ends of the line support autonegotiation, Cisco highly recommends the default auto negotiation settings. • If one interface supports auto negotiation and the other end does not, configure duplex speed on both interfaces; do not use the auto setting on the supported side. • Both ends of the line need to be configured to the same setting; for example, both hard-set or both auto-negotiate. Mismatched settings are not supported. Caution Changing the interface duplex mode configuration might shut down and reenable the interface during the reconfiguration. 14
