Preparing for the CCNP certification? Working as a network professional? Here are all the CCNP-level commands for the ISCW exam you need in one condensed, portable resource. The CCNP ISCW Portable Command Guide is filled with valuable, easy-to-access information and is portable enough for use whether you’re in the server room or the equipment closet.

This book can help you memorize commands and concepts as you work to pass the CCNP ISCW exam (642-825). The guide summarizes all CCNP certification-level Cisco IOS Software commands, keywords, command arguments, and associated prompts, providing you with tips and examples of how to apply the commands to real-world scenarios. Sample configurations throughout the book provide you with a better understanding of how these commands are used in simple network designs.

The topics in this portable command guide cover how to do the following:

  • Implement basic teleworker services
  • Implement Frame-Mode MPLS
  • Implement a site-to-site IPsec VPN
  • Describe network security strategies
  • Implement Cisco Device Hardening
  • Implement Cisco IOS Firewall
  • Describe and configure Cisco IOS IPS

Scott Empson is currently the assistant program chair of the bachelor of applied information systems technology degree program at the Northern Alberta Institute of Technology in Edmonton, Alberta, Canada, teaching Cisco routing, switching, and network design courses in certificate, diploma, and applied degree programs at the post-secondary level.

Hans Roth is an instructor in the electrical/electronic engineering technology department at Red River College in Winnipeg, Canada.
