Incorporating External NICs HowTo

description: Ethernet interface
product: NetXtreme BCM5703 Gigabit Ethernet
vendor: Broadcom Corporation

The dd variable was used in this example to denote the last portion of the MAC address.
Record the information, as shown here:
MAC AddressPCI Bus IDEthernet Device
00:00:00:00:00:0002:00.0eth0
00:00:00:00:00:0103:00.0eth1
00:00:00:00:00:0205:01.0eth2
Complete the corresponding portions of Table 4 (page 14) with the information from this section.
Considerations for the Model Type rx8620
You cannot use PCI bus IDs to configure an additional NIC for the model type rx8620; 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, enter:
# ethtool eth0 | grep detected
Link detected: no
# ethtool eth1 | grep detected
Link detected: yes
# ethtool eth2 | grep detected
Link detected: yes
This indicates that the disconnected Ethernet device is eth0.
4. Repeat steps 2 and 3 for the remaining Ethernet devices.
Complete the corresponding portions of Table 4 (page 14) with the information from this section.
