Can I have multiple NICs in one computer, having same MAC address? OS - Ubuntu Linux. Thanks
Technically it is possible. But the reality is that a lot of funny (and painful) things will start happening. So better do not do it.
If you have a special case we can work with that.
Yep, it's possible. To change the MAC address you can use
ip link set dev <iface> address <mac>
Is it possible to have same MAC address on multiple NICs plugged to same Linux computer?
Will that work as desired/expected?
For instance MAC-addresses are supposed to be unique within the same broadcast domain for TCP/IP to work as designed.
