Intermediate LAN Switching

This chapter starts with an introduction to Cisco IOS software, discussing some basic configuration commands and how to access a Cisco device. Switching concepts are covered in this chapter, including EtherChannels and the Spanning Tree Protocol. You’ll also take a look at the IOS, including configurations and the file system.

To access a Cisco device, you need to use a console cable and connect it to the console port on the router of a computer with a terminal emulator. Your computer needs to be configured as follows (also see Figure 5-1):

  • Speed (baud rate): 9600
  • Parity: None
  • Data bits: 8
  • Stop bits: 1
