How is the OSI model used in troubleshooting?

There are three different ways to use the OSI model: Bottom up – troubleshooting by going from the physical layer (layer 1) up to the application layer (layer 7) Top down – troubleshooting by going from the application layer (layer 7) down to the physical layer (layer 1)Click to see full answer. People also ask, which layer of the OSI model should be the first layer to start your troubleshooting?In any network, most of the problems occur at the physical, data-link, and network layers. Therefore, it is always advisable to start troubleshooting from the physical layer and gradually proceed to the application layer.Also, at what layer do cabling problems occur? IP addressing and routing errors occur at Layer 3. The Physical Layer (Layer 1) and Data Link Layer (Layer 2) are implemented in both hardware and software. The Physical Layer is closest to the physical network medium, such as the network cabling, and is responsible for actually placing information on the medium. Also know, what are some common problems that would fall under certain specific OSI Layer S? Problems that can occur at this layer include, MAC addressing errors, duplex errors, collisions, CRC frame errors, and spanning-tree problems. Ways to detect if Layer 2 errors are occurring are by using various show commands. These include show interface, show port, show spanning-tree commands.How do I troubleshoot a Layer 2 issue?1) Eliminate Layer 1 issue using “show ip interface “command. 2) Verify VLAN exist on the Switch using “Show VLAN “command. 3) Verify that the interface is assigned to the correct VLAN using “show interface switchport” command. 4) Verify that VLAN is allowed on trunk port using “show interface trunk” command.
