Identify device on port

[radovan.vojtek]

Hi all,

i've one port (GigEth, if depends) w/o description and I need to identify device on this port (remotely, indeed ) . I've tried MAC table (empty for that port), I've tried to shutdown the port down and enable it again, I've tried to ping whole subnet - still no MAC entry for that port.

Is there any other way to identify the remote device? As it's the SAN port, i do not want to disable it and wait "what will fall down"

Thanks!

use packet sniffer if you can

Hello Ziga,

thank you for your reply!

Do you mean using SPAN port? Unfortunatelly, there is no free port left on switch and more - I cannot change configuration of any other port in production environment nor have any multihomed device connected to that switch...
