Master troubleshooting of Cisco switches with a systematic approach, using labs and downloadable guides to prepare for CCNA, CCNP, and CCIE exams, including TSHOOT.
Explore a four-router, three-switch switching lab topology with vlan 10 and vlan 20, where a layer 3 switch acts as the default gateway, and diagnose router-to-router ping failures.
Troubleshoot connectivity between router 1 and router 2 by creating VLAN 10 on switch 1 and switch 2, aligning trunk encapsulation to dot1Q, and resolving inconsistent ports to restore ping.
Troubleshoot connectivity between router 1 and router 3 by creating VLAN 20 on switch 2, assigning Ethernet 0/3 to VLAN 20, and bringing up interface VLAN 20 for a successful ping.
Troubleshoot Router 1 to Router 4 connectivity by fixing trunk ports, disabling bpdu guard on Ethernet 0/1, creating VLAN 10, and placing Ethernet 0/2 in VLAN 10 to restore ping.
Explore switching lab 2 topology and tickets, identical to lab 1, diagnose why routers cannot ping, with rule to avoid changing switch two and use only show commands on switch.
Resolve connectivity between router 1 and router 2 by creating VLAN 10, configuring switchport access, and using VTP; fix root guard by making switch 1 the root, then ping succeeds.
Resolve connectivity between router 1 and router 3 by creating VLAN 20 on switch 1 and propagating it to switch 2 via VTP, adjust spanning-tree root guard, and ping verification.
Configure trunks on switches, add VLAN 10 to the trunk, synchronize the VTP domain, and verify full router connectivity through ping tests.
*** Part of the full Course: Cisco Troubleshooting Labs For CCNA, CCNP, and CCIE Students (The best seller course in the IT troubleshooting Category ) ***
Troubleshooting is an essential and important skill for network engineers. As a network engineer, you have to know not just how to configure network devices, but also how to troubleshoot them. And for troubleshooting to be efficient, it has to be systematic and logical and not by random trial and error attempts.
Switches are the foundation of your network, connecting all other devices together. Therefore, knowing how to troubleshot them is the first and the key step in the overall troubleshooting process.
In this course, I will demonstrate troubleshooting of Cisco Switches. You can use this course to learn how to troubleshoot Cisco switches in real production and to help you to prepare for the CCNP TSHOOT exam and the Troubleshooting sections of the CCIE lab exams. If you are already have CCNA level knowledge and/or experience, or you are in the middle of your CCNA studies, then you can use this course as a start for learning advanced troubleshooting.
This course uses multiple explaining ways in addition to videos. At the beginning of the course there is an article for summarized troubleshooting steps that is available for download as a PDF and which I recommend to be read before watching the videos. And for each lab, initial configuration will be available for download in order for students to practice the labs and challenge themselves if they can solve the tickets before watching the videos or even after. In addition, there will be a practice test for the student to check what he has learned. Some tickets have multiple possible solutions. Therefore, restrictions have been set so that there should be only one valid solution.
Let us start the course together and begin the troubleshooting journey. Happy troubleshooting !
