We have Cisco 3560G core switch on our network and we have a mixed flavors of Dlink and HP as slave switches. There are 4 Fiber uplinks ports connected to this switch.
Recently one of the uplink was shut down on the core switch because of the looping on the workstation side.
I have to completely disconnect all the slave switches which were uplinked through the fiber backbone and slowly connected one by one switch to find which port is causing this network looping. Finally I found the port on the switch side.
We have around 1000 network ports and my predecessors didn’t document the cabling numbering properly, and I am not able to find the actual port on the work station side.
Is there a way to find this?
