Determine Physical Port on a Switch

0

Is there any way to use Wireshark to identify which physical port on a switch or, even better, the jack that the computer is plugged into?'

If the port on the switch is running CDP or LLDP, those protocols advertize the physical interface details on the wire which Wireshark can then decode.

As for the actual wire jack, basically there would need to be some information about it conveyed on the wire in order for it to show up in Wireshark so I would say not.
