There was an impression that this is some kind of strictly confidential information that is hidden from the user. I connected the microboard via a network cable to a WiFi router. On the board, the LED indicators blink accordingly, the connection indicator is displayed on the router. The logs of the router indicate that there is a connection to the FastEthernet0 / 4 interface. First, DHCP does not assign an IP to my device, although yesterday it did it once and how it happened I don’t understand. I want to configure manually via PUTTY, but I cannot find out the MAC address of the microboard. Router: ZyXEL

  • I do not quite understand what you want to do after recognizing the mac-address, but you can see all the mac-addresses on the switch port, for this look for specifications for it. Or simply connect the board to the PC (for example) and with the help of wireshark / tcpdump look at the network activity on the PC port. - nobody
  • Assign IP to known mac, is it possible? - Ayrat Arifullin
  • on linux, which is at the heart of most modern router firmwares, it is possible to assign a specific ip to a specific mac. But whether such an option was added to the settings of a specific router depends not only on the manufacturer, but also on the model and even on the firmware version. As for the recognition of mac, few routers can show this until they themselves give out ip. Mikrotik like able to show FDB - Mike
  • The problem is that my microplate gets IP only occasionally, otherwise it seems to be inactive - Ayrat Arifullin
  • one
    So, it is necessary. If I had such a problem before me, I would connect the controller to the PC, pick up some simple dhcpd and use wireshark/tcpdump see how the board and the PC communicate based on rfc 2131. Such cases :) - nobody
