Determining the Private Network Interface
To determine which interface device name is assigned to each network interface, perform the
following steps:
1
Determine the types of NICs in your system.
See Table 1-8 to identify which integrated NICs are present in your system.
For add-in NICs, you may have Intel PRO/100 family or PRO/1000 family cards or Broadcom
NetXtreme Gigabit cards. You may have to open your system and view the add-in cards to identify your
card.
2 Verify that a Broadcom NetXtreme Gigabit or Intel PRO/1000 family NIC is connected with
a Cat 5e cable to the Gigabit Ethernet switch, which is your private NIC.
3 Determine the driver module your private NIC uses (see Table 1-8 above).
4 View the /etc/modprobe.conf file by typing:
more /etc/modprobe.conf
Several lines appear with the format alias eth x driver-module , where x is the Ethernet
interface number and
driver-module is the module you determined in step 3.
For example, the line
alias eth1 tg3 appears if your operating system assigned eth1 to
a Broadcom NetXtreme Gigabit NIC.
5 Determine which Ethernet interfaces (eth x ) are assigned to the type of Gigabit NIC that is connected
to the Gigabit switch.
If only one entry exists in
/etc/modprobe.conf for your driver module type, then you have successfully
identified the private network interface.
6 If you have more than one of the same type of NIC in your system, experiment to determine which
Ethernet interface is assigned to each NIC.
For each Ethernet interface, follow the steps in "Configuring the Private Network Using Bonding" for
the correct driver module until you have identified the correct Ethernet interface.
