Description
These are the steps to change the network interface mode on the Sun Fire[TM] V60/V65 servers.
This procedure can be used to switch between full duplex and half duplex modes, and to change the speed of the interfaces.

Steps to Follow
Setting interface value for linux
To set the interfaces to full duplex, edit /etc/modules.conf and add the
following line:
options e1000 Duplex=2,2
To set the interfaces to half duplex, add this line instead:
options e1000 Duplex=1,1
To set the interface speed to 100, add this line:
options e1000 Speed=100,100
To set the interface speed to 1000, add this line instead:
options e1000 Speed=1000,1000
Then run the following:
depmod -ae
Reboot the server for the changes to take affect.
To view the settings for eth0 or eth1 use the command:
ethtool eth0
or
ethtool eth1
Setting for Solaris[TM] OS:
To set the interfaces to full duplex, edit /kernel/drv/e1000g.conf
Within this file you can set speed and duplex:
ForceSpeedDuplex
-Specify the speed and duplex mode for each instance.
Example:
If you set ForceSpeedDuplex=7,4
the e1000g0 is set to autonegotiate and e1000g1 is set to 100 Mbps, full duplex.
Fiber optic ethernet adapters ignore this setting.
The allowed values are:
1     10 Megabits per second, Half Duplex.
2     10 Megabits per second, Full Duplex.
3     100 Megabits per second, Half Duplex.
4     100 Megabits per second, Full Duplex.
7     Autonegotiate  speed  and  duplex.This is the default.
Reboot the server for the changes to take affect.
