User Tracking—Used in the creation and management of dynamic VLANs. Cisco switches permit
VLAN assignments based on dynamic VLAN assignments. This means the Media Access Control
(MAC) address is used to assign the port to a specific VLAN. User Tracking defines these dynamic
VLANs and maintains the whereabouts of workstations throughout the network.
VlanDirector—Another GUI−based application. It is a very powerful tool to aid in the creation of
multiple VLANs on a switch. This tool helps the administrator add users and assign ports, and it
makes managing VLANs easy.
TrafficDirector—A GUI component that is a great way to create usage baselines and to troubleshoot
switched environments. This tool allows you to view the switched network as well as trunked and
switched ports. A screen capture of TrafficDirector appears in Figure 16.4.

AtmDirector—Used in Asynchronous Transfer Mode (ATM) networks. This tool can be used to
configure, administer, and troubleshoot ATM switched networks.

IOS Software Troubleshooting Commands

Some command−line interface commands are available to aid you in troubleshooting a switch. You can also
use a few GUI applications to simplify some of the functions involved in maintaining and configuring the
Cisco IOS. These applications are helpful and will be discussed later in this chapter.
Let's look at some the commands that you can use to view the switch configuration and perform diagnostics
in order to troubleshoot switch problems and configuration issues. We'll describe the following commands;
then, in the Immediate Solutions section of this chapter, I'll give an example of the output you should see
when using them:
