So Host1 has the correct IP address even though the default gateway is wrong. Hint: On a Linux computer, you will use the ifconfig command instead of ipconfig. Since this is a network problem, what we can do is to check that the IP settings on the host are correct: This tells us that we can focus our efforts on Host1’s connectivity issue. Here we see that Host2 can access the EDGE-RTR but Host1 can’t. In our own case, another device on the LAN is the EDGE-RTR with IP address of 192.168.10.1 so let’s test from each device:
One way we can do this is to test whether each device can reach any other device on the LAN (apart from each other). Now we need to isolate whether the problem is with both devices or just one of them. Note: It is assumed that you have studied the lab setup and that you are familiar with the different IP addresses. 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 always best not to assume that the user is really experiencing the issue and to see if you can replicate it yourself. When did this problem start? What changed on the network that could have caused the problem? In a real-world scenario, you will want to ask questions such as: The most basic troubleshooting scenario you will get as a network engineer is that a computer cannot connect to the network e.g., the user is unable to access some company resource or the Internet. 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. 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? When you’ve got this, then you want to start analyzing why traffic is not flowing that way for those devices and continue drilling down until you find the issue. That being said, there is no one-size-fits-all method for troubleshooting and the method you use will differ from scenario to scenario. 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. We sometimes make the mistake of jumping into troubleshooting without first trying to understand the problem. Troubleshooting is an art that requires great analytical skills and an understanding of how things work.
CISCO PACKET TRACER EXAMPLES SOFTWARE
This study provides evidence in support of the instructional effectiveness of the use of Simulation software tool for the teachers and the learners who are interested in networking concepts.Trblsht_netwk_conn_final.pkt: This Packet Tracer file contains the lab with the issues resolved. This paper presents the features of the simulation tool and analyzes the student’s performance over this simulation soft-ware with the given questionnaires. It includes assessment task with automatic scoring and reporting. One of the best simulation tools for Networking is Packet Tracer which can be freely downloadable from Cisco Networking Academy Students. Now in net, we can find out more simulation software for networking. Like wireless networking labs, if we want to construct the lab with the equipment like wireless router, access points, different cabling it is more cost effective. This is because a topic can be taught effectively to large numbers of people without the need of buying expensive equipment. Simulation tools provide significant cost savings in Education. Rather than just explaining the theory concepts, using animating slides, simulation software that explain the theory concepts easily can be used by the instructor to develop the stu-dent’s skill in the particular subject. Students can more easily understand and adapt the information from the subject, when they can visually see how it really works.
It entails the use of visual aids to convey ideas even more effectively. Practical Learning is a great way of learning as it aids to increase a learner’s interest in a certain subject.
