About This Manual
This document describes command-line interface (CLI) commands you use to view and configure
7200 Series Switch software. You can access the CLI by using a direct connection to the serial port
or by using telnet or SSH over a remote network connection.
Audience
This document is for system administrators who configure and operate systems using 7200 Series
Switch software. It provides an understanding of the configuration options of the software.
Software engineers who integrate software into their hardware platform can also benefit from a
description of the configuration options.
This document assumes that the reader has an understanding of the software base and has read the
appropriate specification for the relevant networking device platform. It also assumes that the
reader has a basic knowledge of Ethernet and networking concepts.
Refer to the release notes for the application-level code. The release notes detail the platform-
specific functionality of the Switching, Routing, SNMP, Configuration, Management, and other
packages. The suite of features the packages support is not available on all the platforms to which
software has been ported.
About the Software
The software has two purposes:
• Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information contained
in the frames.
• Provide a complete device management portfolio to the network administrator.
Note: This document contains both standalone and stacking commands.

Scope
The software encompasses both hardware and software support. The software is partitioned to run
in the following processors:
• CPU – This code runs the networking device management portfolio and controls the overall
networking device hardware. It also assists in frame forwarding, as needed and specified. This
code is designed to run on multiple platforms with minimal changes from platform to
platform.
• Networking device processor – This code does the majority of the packet switching, usually at
wire speed. This code is platform dependent, and substantial changes might exist across
products.
Product Concept
Fast Ethernet and Gigabit Ethernet switching continues to evolve from high-end backbone
applications to desktop switching applications. The price of the technology continues to decline,
while performance and feature sets continue to improve. Devices that are capable of switching
Layers 2, 3, and 4 are increasingly in demand. The software provides a flexible solution to these
ever-increasing needs.
The exact functionality provided by each networking device on which the software base runs
varies depending upon the platform and requirements of the NETGEAR0 software.
The software includes a set of comprehensive management functions for managing both the
software and the network. You can manage the software by using one of the following three
methods:
• Command-Line Interface (CLI)
• Simple Network Management Protocol (SNMP)
• Web-based
Each of the management methods enables you to configure, manage, and control the software
locally or remotely using in-band or out-of-band mechanisms. Management is standards-based,
with configuration parameters and a private MIB providing control for functions not completely
specified in the MIBs.
