Talk to your NAS and reset the IP address to what you want it to be. use the one you say in the ipconfig report.
This will give you a response for every device directly connected to the switch, and then you can do the MAC to IP lookup again. Go to the network card configuration on your PC and change it from DHCP to a fixed IP address. Of course, put your own subnet in the address. If the device is not currently in the ARP table, then you can PING the broadcast from the switch (again, I'm doing this from my 3750X) by doingĪssuming you have a /24 subnet. If you don t have a layer 3 switch, you'll need to do the MAC to IP check on your layer 3 device/router - which means the syntax might be different - but once you've got the MAC address, finding the associated IP address from your network kit is trivial. This'll give you the MAC address of the device connected to the port concerned Switch# show mac address-table | include 1/0/30 Put in the interface number of the interface the NAS is connected to - for example, on my 3750X if I wanted to find the device connected to port g1/0/30, I would do
Can someone please tell me how to find the IP Address of this device? I know the port on the Switch it's connected to? Number of address 224 (16 Million) MAC Prefix. MA-L: Mac Address Block Large (previously named OUI). I have a NAS device which has a static IP Address but it was not documented and now we cannot connect to it.
