Not sure on HP but this doc I have followed for Cisco and the IOS's are similar to a point now. It may point you in the correct way by using ARP and then MAC - IP etc.<br />

You would then go to the next switch and do a show mac-address there. If the address is out a port that goes to another switch, then go to that switch and repeat.

What's the best way to trace exactly which switch and port a device is connected to using only the Mac address on a large network?<br />
<br />
I've done a show mac-address on the core switch and found the Mac address but I think it's connected to another switch, not sure how to figure out which switch this is?<br />

Locate device on network by Mac address

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

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.
