• Explain how to navigate Cisco IOS to configure network devices.

• Describe the command structure of Cisco IOS software.

• Configure a Cisco IOS device using CLI.

• Use IOS commands to save the running configuration.

• Explain how devices communicate across network media.

• Configure a host device with an IP address.

• Verify connectivity between two end devices.
