8. Confirm the hardware address of the newly added interface.
Confirm the hardware address (HWaddr) and the created interface by executing the ifconfig command.
For a single NIC with multiple interfaces, confirm the hardware addresses of all the created interfaces.
Example: eth1 is a new interface created for the added NIC.
# /sbin/ifconfig -a

9. Create an interface configuration file.
Create an interface configuration file (/etc/sysconfig/network-scripts/ifcfg-ethX) for the newly created
interface as follows. In "HWADDR," set the hardware address confirmed in step 8.
If multiple NICs are added or if a NIC where multiple interfaces exist is added, create a file for all the
interfaces.
The explanation here assumes, as an example, that a name automatically assigned by the system is
used. To install a new interface, you can use a new interface name different from the one automatically
assigned by the system. Normally, there is no requirement on the name specified for a new interface. To
use an interface name other than the one automatically assigned by the system, follow the instructions in
step 14 of the
The contents differ slightly depending on whether the interface is a single NIC interface or a SLAVE
interface of the bonding configuration.
