2.2.6.1 MAC-Address for ETH0/ETH1
Each LAN interface is clearly identifiable on the Ethernet via a unique MAC Address (hardware
address).
The MAC addresses given for the LAN interfaces can be read in WebGUI of the appropriate
board or be evaluated via the
hmc
Network Configuration Assistant.
The MAC address for ETH1 is incremented hexadecimal by 1 to the MAC address of ETH0.
Example:
•
MAC address ETH0 = 00:03:C7:12:34:59
•
MAC address ETH1 = 00:03:C7:12:34:5A
The MAC address is uniquely assigned for each LAN interface by the company
hopf
El-
ektronik GmbH.
