Cisco Configuration Reference Guide

Purchase Options:

New Update: Version 4.1.7 – in this update to the Cisco Configuration Guide we completed the following updates: (1) Control Plane Policing. (2) Hierarchical Class-Based Weighted Fair Queuing. (3) 802.1Q Tunneling also called Q-in-Q Tunneling. (4) IPv6 IPSec VPN VTI. (5) We also made other general updates, additional images added, to error corrections discovered during editing.

Reference hundreds of quick sample Cisco configuration for many services and solutions in one comprehensive guide. The largest collaboration of CLI configuration in one place ever released on the Internet. Our packages in our collection focus on the details, design, and further explanation of the configuration. The reference guide provides a quick method to access working configuration to apply and use when needed.

All of the configuration topics in alphabetical order for easy access to find the sample configuration that you need. For example, if you want to find a quick configuration for OSPF summarization you would go to ‘O’ then ‘OSPF’ and find that specific topic of your choice. With this reference guide you can view a sample network picture along with the sample configuration. Simply use that sample configuration for creating your own configuration. This is what we reference for many configurations for our clients today! We have many plans and updates scheduled providing continued value to this reference guide aimed for Network Engineers and Consultants.
