I have got Cisco 3750 switch. The port link changes from green to Amber after almost every 30 minutes. Below is the difnition I pasted from the cisco site.
Link fault. Error frames can affect connectivity, and errors such as excessive collisions, CRC errors, and alignment and jabber errors are monitored for a link-fault indication.
I am pretty sure one of the computers connected to switch causing this issue. can anyone help me how can i found which computer or computers causing network down.
Or do you think this something else causing this issue?
