CCNA Certification – Understanding Interface Characteristics

David Davis Profile: David Davis

This great little video gives you practical information on several show commands relating to the router. Things like show router, show interface, and show network are some of the commands discussed. The video also displays some hot-keys that you could use like the up arrow to display the last command. Also, it discusses some shorten ways of typing the commands. Instead of typing show interface e0, you can type sh int e0. It won’t help in figuring sub-net masks or converting from hexidecimal to decimal but it is an invaluable tool for learning how your router and network work together and how to display trouble areas in the access-list (sh access-list) or there is a possible problem in choosing administrative distance (RIP or OSPF). Check out the YouTube video:
