Chapter 7 Configuring Interface Characteristics
Configuring Ethernet Interfaces
Use the no speed and no duplex interface configuration commands to return the interface to the default
speed and duplex settings (autonegotiate). To return all interface settings to the defaults, use the default
interface interface-id interface configuration command.
This example shows how to set the interface speed to 10 Mbps and the duplex mode to half on Gigabit
Ethernet interface 0/17 and to verify the configuration:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/17
Switch(config-if)# speed 10
Switch(config-if)# duplex half
Switch(config)# end
Switch# show running-config

Adding a Description for an Interface
You can add a description about an interface to help you remember its function. The description appears
in the output of these commands: show configuration
, show running-config , and show interfaces.
Beginning in privileged EXEC mode, follow these steps to add a description for an interface:
Step 6 show interfaces interface-id Display the interface speed and duplex mode configuration.
Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1 configure terminal Enter global configuration mode
Step 2 interface interface-id Enter interface configuration mode, and enter the interface for which
you are adding a description.
Step 3 description string Add a description (up to 240 characters) for an interface.
Step 4 end Return to privileged EXEC mode.
