Incorporating External NICs HowTo

NOTE: The PCI bus ID does not apply to the model type rx8620 server.
• the Ethernet device port
• the Ethernet device's MAC address
On all model types except the rx8620, use the lshw command on the target node to return the
data for the Ethernet interfaces:
IMPORTANT: Do not use the lshw command to determine the Ethernet data for model type
rx8620 nodes. This action could cause those nodes to crash. See “Considerations for the Model
Type rx8620” for information on how to gather the data for the Ethernet interfaces.

This line identifies the PCI bus ID. The PCI bus ID follows the text “pci@”.
NOTE: PCI bus IDs have the following format: xx:yy.z
If two PCI bus IDs are identical except for the z parameter, those buses are on the same
board. For example:
02:00.0
05:00.0
05:00.1
The first bus is on a separate board from the other two, which are usually on the same board.

This line identifies the Ethernet device port.

This line returns the MAC address of the Ethernet device.
If the node is up, run this command to gather the communication data for all the Ethernet devices
on this node. For example:
