ICND1 3.0: An Introduction to Networking and Cisco IOS

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


Expected Duration
186 minutes

You will be able to define the characteristics of a network, host-to-host communications, and the role switches play in a network. This course introduces the concept of networking and host-to-host communication. It presents the OSI model, the TCP/IP stack and the characteristics of a network. It also identifies the need for switches within local area networks (LANs) while introducing Cisco IOS which is the software running on Cisco IOS routers and switches.
