Is not a Valid Static Ethernet Address Vsphere

Is not a Valid Static Ethernet Address Vsphere

When you change the Mac-Address you might encounter an error stating that “Failed to start the virtual machine. XX:XX:XX:XX:XX:XX is not a valid static Ethernet address. It conflicts with VMware reserved MACs for other usage“.

The first six letters of the Mac-Address represents OUI which is vendor specific who manufactures the network card. Mac-Address starting with “00:50:56” are manufactured by VMware.   The next two letters of the MAC addresses must be in a range between 00-3F which is a restriction from VMWare. If you put the the letters outside the range, it will fail to power on. Last 4 letters can be chosen by you.

So if you prefix “00:50:56” VMWare OUI Mac-Address then it  has to be in the range 00:50:56(00 to 3F):XX:XX:XX.

Hope this helps!!
