3.11.3 Ethernet MAC Addresses
The naming of the interfaces may differ depending on the operating system. The MAC
addresses on MC50M are:
Table 20. Ethernet MAC addresses
"00 C0 3A" is the duagon vendor code. The last six digits form the unique MAC address
for each board. The last three digits correspond to the serial number of each MC50M:
Serial number 42 (ETH1):
0x002A = 0x002A.
3.11.4 Ethernet Status LEDs
Table 21. Ethernet status LEDs
The unique MAC address is set at the factory and should not be changed.
Any attempt to change this address may create hardware address
conflicts and thereby render the board inoperable.
