ICND1 3.0: Discovering Ethernet and Troubleshooting Methodologies

Anyone, from junior to senior network administrators, who is responsible for the configuration, maintenance, verification, and troubleshooting of Cisco IOS Routers and Switches.

Prerequisite
None

Expected Duration
177 minutes

Description
You will be able to identify Ethernet LAN media, describe the functions of a switch, and troubleshoot communication issues with a structured plan. This course focuses on Ethernet networks. It will identify the different types of Ethernet connections and cables that are available as well as the addressing that is needed for Ethernet communication within a LAN. It will also describe how switches handle the different types of frames that may be received on an interface and how to troubleshoot connectivity issues with the LAN.
