Chapter 4: Linux Base Driver for PRO/1000 Family of Adapters
4-5 Additional Configurations
Configuring the Driver on Different Distributions
Configuring a network driver to load properly when the system is started is distribution
dependent. Typically, the configuration process involves adding an alias line to
/etc/modules.conf or /etc/modprobe.conf as well as editing other system startup scripts
and/or configuration files. Many popular Linux distributions ship with tools to make these
changes for you. To learn the proper way to configure a network device for your system,
refer to your distribution documentation. If during this process you are asked for the
driver or module name, the name for the Linux Base Driver for the Intel® PRO/1000
family of adapters is e1000.
As an example, if you install the e1000 driver for two PRO/1000 adapters (eth0 and
eth1) and set the speed and duplex to 10full and 100half, add the following to
modules.conf or /etc/modprobe.conf :
alias eth0 e1000
alias eth1 e1000
options e1000 Speed=10,100 Duplex=2,1
Viewing Link Messages
Link messages will not be displayed to the console if the distribution is restricting system
messages. In order to see network driver link messages on your console, set
dmesg to
eight by entering the following:
dmesg -n 8
Jumbo Frames
Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
to a value larger than the default value of 1500. Use the
ifconfig command to increase
the MTU size. For example:
ifconfig eth<x> mtu 9000 up
This setting is not saved across reboots. The setting change can be made permanent by
adding MTU=9000 to the file:
/etc/sysconfig/network-scripts/ifcfg-eth<x> (Red Hat
distributions). Other distributions may store this setting in a different location.
NOTE: This setting is not saved across reboots.
NOTE: To enable Jumbo Frames, increase the MTU size on the interface
beyond 1500.
