Safety Information and Technical Specifi cations
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
NOTE: This setting is not saved across reboots.
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 ifconfi g command
to increase the MTU size. For example:
ifconfi g 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 fi le: /etc/sysconfi g/network-scripts/ifcfg-
eth<x> (Red Hat distributions). Other distributions may store this setting in a
different location.
NOTES:
To enable Jumbo Frames, increase the MTU size on the interface beyond 1500.
