I have a stack of Nortel 5650 switches. We currently have a single, flat network, but will be breaking out traffic accross multiple VLANs in the near future.
I am looking for a way to identify which physical port on the switch is associated with particular IP addresses (i need to move the majority of the ports to a different VLAN, but dont want to move any network devices, printers, etc).
i have been able to find a few statically assigned IP addresses by viewing the arp cache - but that is not working for all.
What is the best way to do this?
