this guide explains how to install, maintain, and troubleshoot your router hardware. it also includes instructions for the router rom monitor and virtual configuration register.

    although this guide provides minimum software configuration information, it is not comprehensive. for detailed software configuration information, see the cisco ios configuration guide and command reference publications. these publications are available on the documentation cd-rom that came with your router, or you can order printed copies. (see "obtaining documentation" for more information.)

    this guide describes several router models that are similar in functionality, but differ in the number of interfaces supported. some information provided may not apply to your particular router model.

    warranty, service, and support information is in the cisco information packet that shipped with the router.
