This means you start by pinging between the two devices that cannot communicate.
It can be a hardware fault, someone plugging a PC in the wrong port, or anything else you need to fix. The technical term for a ticket is, in reality, incident: here’s the definition.Īn incident (ticket) is an issue in the infrastructure causing it to behave unexpectedly. Cisco introduces you to troubleshooting with the concept of the ticket, and because of that, we will do the same. You won’t implement anything new, but instead, you are going to work with issues. Since this article is all about switch troubleshooting, there is no specific configuration requirement. We will have to jump on the core device (TopSwitch元) and then telnet into other switches. Instead, we must check the configuration on the switches, doing real switch troubleshooting. This way, we cannot simply see where the cable goes.
We need to find out with troubleshooting.Īfter that, we have hidden all the switches. In the cloud, we have three switches, but we cannot see how they interconnect devices. This is the topology we are going to work in.
