Preparing for the CCNP® ROUTE or CCNP SWITCH exam? Working as a network professional? Here are all the CCNP-level commands you’ll need, in one handy resource. The CCNP Routing and Switching Portable Command Guide is filled with valuable, easy-to-access information, and it’s portable enough to use whether you’re in the server room or the equipment closet.
This guide helps you memorize commands and concepts as you prepare to pass the CCNP ROUTE (300-101) or CCNP SWITCH (300-115) exams. It summarizes all CCNP certification-level Cisco IOS® Software commands, keywords, command arguments, and associated prompts, offering tips and examples for applying them in real-world environments. Throughout, configuration examples deepen your understanding of how these commands are used in actual network designs.
Whenever you’re researching routing or switching solutions, you won’t find a quicker, more useful offline resource.
