Command to find mac address on network7/12/2023 ![]() Without it, you will not see MAC addresses. The command will list machines that respond to the Ping and will include their MAC address along with the vendor. However, I'm thinking by now you already figured this out. Open Nmap (or Zenmap) and use the command sudo nmap -sn (network IP) to scan the entire network (without port scan). In summary, you'll want to be careful and key off indicators such as in ifconfig noting: status: no carrier vs active and for those with IP assignment on the individual interface, you can match via the inet address. To use it, open a Command Prompt or Windows Terminal window and type ipconfig / all. I have exhibited the following alignment where ext-1 = em2 (from the list of em0, em1, em2, and em3) You can also find your network adapter’s MAC address by running the ipconfig command via the Command Prompt, Windows Terminal, or Windows PowerShell in Windows 10 or 11. ![]() For instance ( color coding used to emphasize what one *may* expect):Įven the InfiniBand ports don't align as you *may* expect:ġ) When you have the 2 on-board (Cu) 1gig interfaces, the numbering while it doesn't match, is at least aligning in ascending order: ( em0 = ext-1 and em1 = ext-2)Ģ) However, notice the 10gig interfaces where while cxgb1 = 10gige-1 (number reference matches), *but* then cxgb0 = 10gige-2 which doesn't match the ascending order.ģ) This changes when you have 4x (Cu) 1gig interfaces (2x onboard + 2x expansion). ![]() Simply wanted to point out that mapping the (individual) interface names at the OS level (via ifconfig) to the naming used by OneFS could be a bit confusing.
