CCNA Lab Practice with Cisco Packet Tracer: Troubleshooting Network Connectivity

This means that a candidate should definitely pay attention to such a section. In this lab and later labs, we will be looking as different troubleshooting scenarios and how to resolve them, not just from an I-want-to-pass-the-exam point of view but from a real-world angle.

We will be using the following setup for this troubleshooting scenario, which covers sections 7. A couple of problems have been reported on the network above: Host1 and Host2 cannot communicate with each other. Even though Host2 can access the web server using www. Resolve these issues making sure there is connectivity between the hosts and that the hosts can access the web server. Two files are attached to this article: This Packet Tracer file contains the lab setup with the problems described above.

This Packet Tracer file contains the lab with the issues resolved. A Note on Troubleshooting Troubleshooting is an art that requires great analytical skills and an understanding of how things work.

We sometimes make the mistake of jumping into troubleshooting without first trying to understand the problem. As a result, we fumble about with different tools and methods in a brute-force manner instead of taking a step back to understand what is going on. That being said, there is no one-size-fits-all method for troubleshooting and the method you use will differ from scenario to scenario. For example, if you are dealing with Layer 3 IP forwarding, you probably want to start with understanding the traffic flow: How is traffic supposed to flow from device A to device B?

On the other hand, if you are troubleshooting why two routers are not forming EIGRP neighbor adjacency, then you will use another method — one that is specific to EIGRP like checking K-values, and so on. Troubleshooting Scenario Resolution The most basic troubleshooting scenario you will get as a network engineer is that a computer cannot connect to the network; e. In a real-world scenario, you will want to ask questions such as: Is this the only user affected or are all users on the network or a subset of users affected?

When did this problem start? What changed on the network that could have caused the problem? It is always best not to assume that the user is really experiencing the issue and to see if you can replicate it yourself. In this type of scenario, you usually have access to the computer that is experiencing issues and one of the easiest things to kick your troubleshooting off with is Ping. It is assumed that you have studied the lab setup and that you are familiar with the different IP addresses.

As you can see, the problem really does exist. Now we need to isolate whether the problem is with both devices or just one of them. One way we can do this is to test whether each device can reach any other device on the LAN apart from each other.

Since this is a network problem, what we can do is to check that the IP settings on the host are correct: On a Linux computer, you will use the ifconfig command instead of ipconfig. So Host1 has the correct IP address even though the default gateway is wrong. This is where understanding comes in: At this point, you want to make sure that the device is properly connected to the network, i.

Since we are using Packet Tracer, this step will not apply. The next device to check is the switch to which the device is connected to. In this step, we will check things like the state of the port up or down , its VLAN membership, its switchport mode, etc.

We will use commands such as show interface, show vlan brief and show run. The next output, however, reveals something: We have solved the first problem. The second problem is that Host1 cannot access the web server even though Host2 can. Again our focus will be on Host1, since the issue is specific to that host. Thinking about the problem for a minute, two things come to mind: While troubleshooting the first problem, we already saw that the default gateway was wrong.

So we can change that from the IP Configuration tool. If you are observant, you should also notice that the DNS server is wrong— With both changes made, if you try to open that URL again, it should work: Summary This brings us to the end of the lab where we began our troubleshooting series. The scenario presented in this lab is very simple and we will encounter more difficult labs as we go along.

I hope you have found this article helpful.
