Not all switches nessasarily have IP addresses. Would it do layer 2 discovery?

I need to be able to identify even layer-2 hubs and which computers are connected to it.

What is the purpuse of that? Are you looking into comercial products? Do you want to do Inventory or some kind of policy?<br />
<br />
I would recomand portnox if you are looking for Access Control solution, although you do need to enter the managed switches manually...<br />
<br />
Just for scope scanning (IP) you can use nmap as well

Inventory. I'm trying to replace couple of switches need to know how those switches are attached to core router and what else is attached to them, without doing to much cable tracing.

I'm looking for a tool which would allow me to do some basic discovery of workgroup layer switching equiment. Environment has switches of different brands: Cisco, Netgear, Dell etc. <br />
I need to find out the following - how switches are connected,to each other and which devices are attached to a particular switch. &nbsp;<br />
Recomendations? <br />

Switching Environment Discovery

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.
