The port was showing a green light (which it should). After some time it started turning orange and then back to green. This was due to an output that was going to another part of my network. When I took that output out then there was no collision, and as soon as I put it in the same thing would happen. Could you tell me what exactly is the problem?
Do you manually hardset all your interfaces to full (or half) duplex? Or do you use auto-negotiation? DO NOT TRUST AUTO-NEGOTIATION. Always hardset your ports. As troublesome as that can be, it will save you a lot of time in the long run.
