All the CCNA®-level commands in one compact, portable resource

With hundreds of Cisco IOS® software commands, options, and command arguments to remember, a CCNA® candidate has a lot to commit to memory. Organizing your own engineering journal with notes is a task unto itself, and online resources are not always available. Now there’s help from the CCNA Command Quick Reference.

Filled with handy tips and examples on how to apply the commands to real-world scenarios, this easy-to-use, portable reference will help increase your familiarity with Cisco IOS software when working on routers and switches or in simulated networks. CCNA Command Quick Reference summarizes all commands with keywords, command arguments, and associated prompts. The book includes many configuration examples, visually diagramming a network with related configuration and output. It also includes unique references on subnetting, variable-length subnet masking (VLSM), and common router configuration steps.

Designed as a memory booster, this book is an excellent supplementary guide for students in the Cisco networking Academy® Program CCNA curriculum or anyone Reviewing for the CCNA exam (640-821 INTRO, 640-811 ICND, or 640-801 CCNA).

Topics are covered in the order of modules in the four CCNA networking Academy courses:
