If youIf you want the port to be displayed all the time, you can click the menu "Options" a "Preferences", open the dialog box shown in Figure 4-M2, and check "Show Port LabelThe checkbox "Label". The user can customize it, such as turning off animation and sound, hiding the device label, showing the port label, etc. The topology diagram after showing port labels and hiding device labels is shown in Figure 4-1-13. If the reader is not used to this interface, the Show Port Label option can be removed.Figure 4-1-13 Topology diagram showing port labels This completes the installation of the PacketTracer software and the design of the topology. Save this topology and open it directly when you use it later. Click the "Save" icon to open the Save dialog box shown in Figure 4-1-14. Make a file name for saving. The Chapter 2 video section of the CD describes the use of Packet Tracer simulation scenarios, and Packet Tracer is simply unparalleled for teaching purposes.k82 Figure 4-1-12 Selecting the Show Port Labels check boxTalking Together Chapter 4 Cisco Routers .

Here is another classic router and switch simulator, Dynamips, and I would like to thank the author of Dynamips, "Chris", for his hard work and making this a convenient learning opportunity. Although there have been many Cisco router and switch simulators in the past, no router and switch simulator can compare to Dynamips because it is fundamentally different from the previous simulators. First of all, Dynamips simulates the hardware of the router and switch, and it is up to the user to decide what version of IOS (Internet Operate System, the operating system of the router or switch, equivalent to whether the computer installs Windows XP, Windows Server 2003, etc.) to load. Dynamips simulated routers have all the functions of real routers; secondly, Dynamips simulated routers and switches can be interconnected with real networks, and can even be used in actual production environments, while the previous simulators are only a virtual environment and cannot be connected to real network.If Dynamips is so good, why is the Packet Tracer simulator introduced earlier? This is because Dynamips can only simulate routers, and although you can install switching modules on routers to simulate switches, the configuration commands are subtly different from those of most pure switches nowadays, and in order not to affect your ability to take the CCNA exam, many of the experiments in this book involving In order not to interfere with taking the CCNA exam, many of the experiments involving switching in this book are mostly done in the Packet Tracer simulator. In order to bring the reader closer to the real environment and develop more engineering experience, most of the configuration and experiments are done in Dynamips as much as possible, and only those that cannot be done in Dynamips are considered to be done in the Packet Tracer simulator.
