The purpose of this tech note is to provide a complete setup guide for a cable modem (CM) network in a lab
environment. This setup can be used as a first step before deployment to a customer network. It is important to
note that a trouble−free setup in the lab does not necessarily mean a trouble−free setup in a customers
network. In a controlled lab environment, noise may not be an issue; while in real life, it can be quite the
opposite. However, this procedure can be used to rule out issues that arise from the Cisco IOS® Software
Release, the configuration, the hardware, and Radio Frequency (RF).

There are no specific requirements for this document.

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.
