Determining the Private Network Interface
To determine which interface device name is assigned to each network interface, perform
the following steps:
1 Determine which types of NICs are in your system.
Refer to table Table 1-7 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
determine which you have.
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. This is your private NIC.
3 Determine which driver module your private NIC uses.
The Broadcom NetXtreme Gigabit uses
tg3 , and the Intel PRO/1000 family uses e1000 .
4 View the /etc/modules.conf file by typing:
more /etc/modules.conf
Several lines appear with the format alias ethX 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 ) have been assigned to the type of Gigabit NIC
that is connected to the Gigabit switch.
If there is only one entry in
modules.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" for the
correct driver module until you have identified the correct Ethernet interface.
