The dd variable was used in this example to denote the last portion of the MAC address.
Record the information, as shown here:

Considerations for the HP Integrity rx8620 rx8620
You cannot use PCI bus IDs to configure an additional NIC for the HP Integrity rx8620 model
type; instead you must use the Ethernet device name. Use the ifconfig -a command to
determine the MAC address for each Ethernet device:
# ifconfig -a | grep eth
eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:10
eth1 Link encap:Ethernet HWaddr 00:00:00:00:00:20
eth2 Link encap:Ethernet HWaddr 00:00:00:00:00:30
...
The value following HWaddr in this line is the MAC address for the corresponding Ethernet
device. If you are unsure of which Ethernet device is which, use the following procedure:
1. Determine the number of Ethernet devices from the ifconfig -a command. In this
example, there are three: eth0, eth1, and eth2.
2. Disconnect one of the Ethernet devices from the node and take note which one you
disconnected.
3. Enter ethtool ethn | grep detected on the command line for each of the Ethernet
devices.
In this example, the command was entered each time for eth0, eth1, and eth2:
# ethtool eth0 | grep detected
Link detected: no
# ethtool eth1 | grep detected
Link detected: yes
# ethtool eth2 | grep detected
Link detected: yes
