Subject: Determine network devices on flat network
> Hello everyone and Happy New Year -

> I have about 20 switches set up as a flat network with no VLANs
> (10.0.0.0). Different device groups all have a common second octet
> (clients are 10.0.x.x, printers are 10.1.x.x, servers are 10.2.x.x) but
> the network is flat, as they all use a /8 (255.0.0.0) mask. The
> printers, for example, are scattered across all switches but have
> 10.1.x.x addresses. I need to find out what physical ports each printer
> is plugged into. I have ping-swept the 10.1.x.x range and found about
> 150 printers total. However, I need to now find out what switch port
> each printer connects to (actually all I need to know is which switch,
> not necessarily which port).
