10/27/2017 TestOut LabSim 1/2 6.7.2 Switch Troubleshooting Facts The following table lists several problems you might encounter when managing switches on your network: Issue Description Collisions A collision occurs when two devices that share the same media segment transmit at the same time. In a switched network, collisions should only occur on ports that have more than one device attached (such as a hub with workstations connected to it). To eliminate collisions, connect only a single device to each switch port. For example, if a hub is connected to a switch port, replace it with another switch. If collisions are still detected, troubleshoot cable and NIC issues. Duplex mismatch A duplex mismatch occurs when two devices are using different duplex settings. In such a case, one device will try to transmit using full duplex, while the other will expect half duplex communications. By default, devices are configured to use auto- negotiation to detect the correct duplex setting to use. If a duplex method cannot be agreed upon, devices default to half duplex.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
