I am working on a Rack Clean up project. I can not remove any wire until I know 100% what device is attached to my switches. I am dealing with Cisco 2950s and 3750s. I can not trace the wires because I am not allowed to go under the Data centers floors. Is there a command or program out there that I can run that will let me know what the other devices Mac address and or IP address are. I am using what ever information I can and I have a few IP addresses but Im not 100% that the device that is answering is the next hop over.
