Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring the Interface Speed
Follow these steps to configure the speed of a layer 2 interface.
Step 1 Enter enable mode.
Router> enable
Router#
Step 2 Enter configuration mode.
Router# configure terminal
Router(config)#
Step 3 Enter configuration for the interface that you want to modify.
Router(config)# interface fastethernet 1/0
Step 4 Specify the interface speed. You can set an interface to 10 Mbps, 100 Mbps, or autonegotiate.
Router(config-if)# speed [10 | 100 | auto ]
Configuring the Interface Duplex Mode
Follow these steps below to set the duplex mode of a layer 2 interface.
Step 1 Enter enable mode.
Router> enable
Router#
Step 2 Enter configuration mode.
Router# configure terminal
Router(config)#
Step 3 Enter configuration for the interface that you want to modify.
Router(config)# interface fastethernet 1/1
Step 4 Use the duplex command to set the interface to send traffic at full duplex, half duplex, or to
autonegotiate its duplex setting.
Router(config-if)# duplex [auto | full | half]
You can use the show interfaces command to verify the duplex configuration.
Note If you set the port speed to auto on a 10/100-Mbps Ethernet interface, the interface auto-negotiates the
speed and duplex settings. You cannot change the duplex mode of interfaces set to auto-negotiation.
Configuring a Description for an Interface
You can add a description of an interface to help you remember its function. The description appears in
the output of the following commands: show configuration, show running-config, and show
interfaces.
