With hundreds of Cisco IOSA (R) Software commands, options, and command arguments to remember, a CCNAA (R) candidate has a lot to commit to memory. Having an easy-to-use, portable reference filled with handy tips and examples on how to apply the commands to real-world scenarios will help increase users familiarity with Cisco IOS Software when working on routers and switches. Also having references on subnetting, variable-length subnet masking (VLSM), and common router configuration steps will serve as great memory joggers for those just starting out in networking or cramming for the CCNA exam. The CCNA Portable Command Guide is a supplementary guide to assist network administrators in the proper use of the Cisco IOS and of the commands needed to pass the CCNA vendor exam. The guide summarizes all CCNA-level commands, keywords, command arguments, and associated prompts. Configuration examples are provided throughout the book to give a better understanding of how these commands are used in simple network designs.This guide is not meant to replace any existing learning materials but rather serve as a supplementary guide to assist networkers in the proper use of the many different commands that are required to successfully pass the CCNA vendor exam process, whether the one-exam or two-exam more
