i ended up just pinging the IP - and that was enough to force it to populate the arp cache. &nbsp;I thought i had tried that before i posted the question. &nbsp;thanks for your help.

Machine can have MAC on port but no IP.

Unic equivalent of IP tracker is arpwatch<br />
When you get IP conflict you look where abuser is connected.<br />

I have a stack of Nortel 5650 switches. &nbsp;We currently have a single, flat network, but will be breaking out traffic accross multiple VLANs in the near future. &nbsp;<br />
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).<br />

i have been able to find a few statically assigned IP addresses by viewing the arp cache - but that is not working for all.<br />
What is the best way to do this? &nbsp;<br />

Nortel 5650 stack of switches - find IP plugged into a specific port

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
