Note: PT does not support the show ip default-gateway command used in the example. The show dhcp lease command used in this example includes default gateway info. We did not support. You can, however, experiment with the ipconfig command in PT. You can also open a command prompt on your own computer and try the commands that match your OS per the various examples. I have a question about a command you show in Vol2-Chapter 7. I tried to run the command on different platforms CML, PT, and on real a bit old hardware but is not vailable in any of the them.
I just type the whole command without short keys or autocoplete and it works?!?!? So this command has no help support? But, your instincts are correct. I just tried it on a and X. No help, but the command works, even abbreviated, as long as it was unique vs. EG: sh ip def worked for me.
Real Cisco gear would not include 3. PKT does not except the brief option. Uses can use show ip ospf interface and look through the output to find the information needed. Note that PT does not include that same section of output in the version of PT 7. The example lists two alternative configurations, so we supplied two PT files. PT does not support the brief option on the show ip ospf interface brief command, but you can use the command without the brief keyword to find more detailed information.
I just purchased CCNA and early in the ebook, there is a link to this website. In this case, was able to download the PKT. But, where are the labs? Usually in the past there would be a lab that would open up and required to follow the lab? Is there a seperate book. Plus the chapters here, such as Chapter 20 do not match the book?
Paul, Sorry you found it confusing. Let me clarify. Short version: A post like this one helps you re-create the examples in the book. These posts are not separate lab exercises. Maybe the page linked above is enough to connect the dots. Hope this helps! See the accordion table at the end of the post, EG, for example Start Cisco Packet Tracer. From the top menu, select Help… Contents.
The following figure shows a screen capture from the help system. Note the table of contents on the left side. Cisco Packet Tracer provides a useful lab environment, but it does not tell you what to do. It's like buying a bunch of tools at the hardware store, getting home, and wondering what you can make with your great new tools.
In this case, what routing and switching features should you configure and verify? What topologies make sense? What should the goals be for routing and switching? What specific commands should you use? If you feel comfortable just taking PT and making up what to do, great! But for those who want some tips, I'll explore three approaches you can take to figure out how to decide what to do:. Clearly, you could practice the commands you learned so far in whatever course or book you are using for CCNA.
But that doesn't give you much to go on. Whatever CCNA course you take live or video or book you read, it will show examples with a topology, explain what should happen, and then list the configuration and verification steps and commands. Use those — and then do variations on that theme. I've formalized it a bit to help you along with these major activities:. Look back for examples that require configuration and verification, with a figure showing routers and switches, along with text explaining the configuration before the example and the configuration to be added.
For example, you might see a figure like the one below that states that the switch needs to be configured with VLANs, and the ports need to be assigned to those VLANs.
Step 1: Create the topology for your chosen example. Also, re-creating the example may be easier to match the same interface IDs between the example and PT. For those of you just getting into networking, creating the topologies can be a great learning experience all by itself. As I noted in the introduction to this article, some of you may not have or have access to any Cisco hardware. Working through the PT design tools to create a supplied topology helps you learn about real Cisco hardware — it's well worth the effort.
Step 2: Predict the initial configuration required by the example — and configure it. Almost every example in a CCNA course or book has a figure that shows the topology, along with some configuration and verification commands that help you learn the topic. But that example may have some initial configuration, either implied or stated. For instance, your course likely has examples about configuring OSPF a routing protocol. Making yourself think about that initial configuration state of an example helps you review your learning and commands.
Then configuring the commands allows you to review the particulars of each command. Step 3: Configure as shown in the example. If it shows configuration commands, then you configure those same commands in PT.
Did the commands work? Do you understand what happened? Try those in PT and think about the output. Does it match what you see in your course? If it differs, do some troubleshooting. Step 4: Create a Similar Example: You do not have to re-create the same examples from a book.
Instead, try and create a similar example, just different enough to make you think about how to change the configuration.
Use different VLAN numbers, different subnets, different interfaces, different topologies, different numbers of switches and routers. Explore and enjoy! Packet Tracer has several wonderful portability features. For example, when you create a topology and configure devices, PT stores all that content in a single file filetype.
Then you can share the file with anyone, and they can open it if their version of PT is at least as recent as yours. Those same sharing features allow anyone to create lab exercises that include. You will likely soon be getting many opportunities to download files, open them in PT, and follow scripted lab exercises that happen to use PT. Once you've found a source of some labs, the overall flow will be:. Download one or more. For a single lab, open the specified. Follow the lab exercise steps. The lab may integrate the steps into the PT user interface or supply the steps as a separate document.
At the beginning configuration activities can be difficult but with more practice it becomes easy and funny for a network engineer. By practing thesse labs, you will become more familier to Cisco Command Line Interface and after a while you will automatically configure almost all network protocols and topologies. This special page of IPCisco. You can practice with these files or build your own topology on your computer with the help of these files. With more practice, you will get more familier to the configuration lessons of CCNA So, you should practice more on the configuration lessons.
You can download them and practice by yourself. If there is a missing one,m do not worry! It will be added shortly.
Packet Tracer is known as a beginner similuation program. But in recent years, it has developed a lotm and become very well especially for CCIE level labs. Especially fort he junior network engineers, it is an amazing tool. Because, downloading, installing and using packet tracer is very easy. Beside this user friendly part, it do not make your computer heavy.
