Express slot number. You can confirm that it matches the mounting location of the operational target NIC.
2. Collect information about interfaces on the same NIC.
For a NIC that has more than one interface, you will need to deactivate all the interfaces on the NIC. Use
the following procedure to check each interface that has the same bus address as that confirmed in step
1. Then, make a table with information including the interface name, hardware address, and bus address.
Note
Collect the following information even if the NIC has only one interface.
- Confirm the correspondence between the bus address and interface name.
Execute the following command, and confirm the correspondence between the bus address and
interface name.
Example: The bus address is "0000:0b:01".
# ls -l /sys/class/net/*/device | grep "0000:0b:01"
lrwxrwxrwx 1 root root 0 Sep 29 10:17 ¥
/sys/class/net/eth0/device
->../../../0000:00:01.2/0000:08:00.2/0000:0b:01.0
lrwxrwxrwx 1 root root 0 Sep 29 10:17 ¥
/sys/class/net/eth1/device
->../../../0000:00:01.2/0000:08:00.2/0000:0b:01.1
The ¥ at the end of a line indicates that there is no line feed.
The following table shows the correspondence between the bus addresses and interface names from
the above output example.

Note
When recording a bus address, include the function number (number after the period).
- Confirm the correspondence between the interface name and hardware address.
Execute the following command, and confirm the correspondence between the interface name and
hardware address.
Example: eth0 [For a single interface]
# cat /sys/class/net/eth0/address
00:0e:0c:70:c3:38
Example: eth0 [For a bonding interface]
The bonding driver rewrites the values for the slave interface of the bonding device. Confirm the
hardware address by executing the following command.
# cat /proc/net/bonding/bondY
Ethernet Channel Bonding Driver .........
.
.
Slave interface: eth0
.
Permanent HW addr: 00:0e:0c:70:c3:38
.
.
You can use this procedure only when the bonding device is active. If the bonding device is not active
or the slave has not been incorporated, use the same procedure as for a single interface.
Also, the correspondence between the interface name and hardware address is automatically
registered by the system in the udev function rule file, /etc/udev/rules.d/70-persistent-net.rules.
Confirm that the ATTR{address} and NAME items have the same definitions as in the above output.
Example: eth0
