Cisco LAN Switching Fundamentals: Configuring Switches

Chapter Description

This chapter provides guidance and configuration examples for connecting switches running both native and hybrid software configurations, and offers examples of both Layer 3 and Layer 2 connectivity between switches.

Configuration Overview

Figure 7-2 shows a diagram of four switches that are yet to have any connections configured. These four switches comprise the primary components of the network that will be configured and added onto throughout the remainder of this chapter.

A mix of platforms, software levels, and interfaces was chosen to provide a variety of configuration examples. Table 7-2 lists the switches in use.

The software versions installed on these switches are not recommendations for these platforms, only versions that support the modules and features required for these exercises. Administrators should utilize the tools on the Cisco Software Center at Cisco.com, such as the IOS Upgrade Planner, Software Advisor, and Cisco Bug Navigator, to help select a satisfactory software level. After a software level has been selected, administrators should reference the release notes for a list of Open and Resolved Caveats in that version.
