on my earlier install yesterday I had both WiFi and ethernet running at the same time. The MAC was the same,
I can't find any mention of what Raspberry Pi hardware you are using.
But I would expect each network interface to have a unique MAC address.
This is from an RPi 3B+
Code:
pi@RPi3BplusOffice:~ $ ip link show eth02: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether b8:27:eb:fd:34:bd brd ff:ff:ff:ff:ff:ffpi@RPi3BplusOffice:~ $ ip link show wlan03: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether b8:27:eb:a8:61:e8 brd ff:ff:ff:ff:ff:ffpi@RPi3BplusOffice:~ $ And this is from an RPi[5]
Code:
david@rp54bw64full0512:~ $ ip link show eth02: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether d8:3a:dd:a9:b1:f5 brd ff:ff:ff:ff:ff:ffdavid@rp54bw64full0512:~ $ ip link show wlan03: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether d8:3a:dd:a9:b1:f9 brd ff:ff:ff:ff:ff:ffdavid@rp54bw64full0512:~ $ Wireless might be able to cope, but for cabled Ethernet having a unique ethernet MAC address is a fundamental part of how the protocol works and I would anticipate 'bad' (unpredictable, unreliable) things to happen if there are duplicate addresses present on a LAN.
