(ETA: What if you can't get to the Console port? How do you get the IP address of the switch in order to SSH or (if you must) Telnet in?)Ĭouldn't you just use CDP? #show cdp nei detail will show you the ip of the connected devices. The amazing thing to me is, this far into the 21st Century, this is still the only way I could find to get this information - i.e. Also, 'sh ip arp | i 0/24' will show just the MAC address(es) on that port.) Scroll down to see your IPv4 and IPv6 addresses. If you're all Cisco, 'show cdp neighbor' (or 'sh cdp nei') will get you to the next switch. To find the IP address of your device, go to Command Prompt, and type ipconfig. (Small tip: When you see a large number of MAC addresses showing up on a single port, there's a switch on that port into which those MAC addresses are connected. It helps to Ping the subnet's broadcast address (e.g. :^D After beating Google to death over it, hoping for some useful tool, I ended up using exactly the same process (plus the online MAC address lookup to ID the device manufacturer), so I can affirm this works perfectly, if you work it.Īs you can see, the 'sh arp' or 'sh ip arp' commands also give you the MAC addresses, so essentially the 'sh mac add' is only to get the port in which the device is connected. Thanks for posting this *after* I finished a "What's Connected Where" jihad on our network. Click on the 'Spotlight' icon in the top menu bar (far right) Type 'Terminal' in the search field and press 'Enter'.
