Cisco 3750G and 3560G Configuration for WheatNet-IP
Overview
Let’s take a look at what needs to be done to get your Cisco 3750G/3560G ready
for the installation of your Wheatnet-IP system. Properly configuring your switch
allows you to take advantage of the “management” capabilities to control network
traffic and allows the network to operate at its highest potential. This becomes
necessary to prevent overloading the network as the system size increases.
In this setup process you will setup switch ports according to the type of device
connecting to that port. You will be setting things like VLAN access, Trunking,
Speed, etc. Each section below gives you the exact commands needed to get your
Wheatnet-IP network up running.
Below is a chart that gives you some information about the command you will be
using to complete the setup. This can be a quick reference for you as

This document will explain the initial configuration of the Cisco 3750G/3560G
switch. To get started you will need the blue console cable that came with your switch.
Go ahead and connect the console cable to the serial port on your pc and the RJ-45
to the console port on the switch. If your pc is not equipped with a serial port you will
need a USB to Serial converter.
Next let’s get your pc ready to communicate. You will need a terminal program
such as HyperTerminal to finish this portion of the setup. HyperTerminal is an
application you can use in order to connect your computer to other remote systems.
These systems include other switches, routers, other computers, and Telnet sites.
HyperTerminal is located under the Start menu of your Windows 2000/XP PC. If
you are using Windows Vista or Windows 7 you will need to install a similar terminal
program to complete the setup.
