Configuring the Driver Parameters |
The e1000g (Solaris) and e1000 (Linux and Windows) device driver controls the Sun x4 PCI-Express Quad Gigabit Ethernet interfaces. You can manually set the e1000g or e1000 device driver parameters to customize each device in your system.
This chapter lists the available device driver parameters and describes how you can set these parameters.
Each of the four e1000 channels provides 10BASE-T, 100BASE-T, or 1000BASE-T networking interfaces. The device driver automatically sets the link speed to 10, 100, or 1000 Mbit/sec and conforms to the IEEE 802.3 Ethernet standard. The single MAC/PHY chip provides the PCI-E interface and media access control (MAC) functions.
The e1000 driver is capable of the following operating speeds and modes:
TABLE 5-1 describes the functions of the e1000g driver parameters.
You can view the driver parameter settings by using the e1000g.conf file:
TABLE 5-2 lists the tunable e1000 driver parameters for Linux operating systems, and describes their function.
In a Linux operating system, the driver parameters can only be set at the time the driver is loaded. If you have already loaded the driver and have not set the parameters at the same time, remove the driver and reinstall it.
Use ethtool to change operating speeds and modes.
ethtool -s eth14 speed 1000 duplex full autoneg on ethtool -s eth15 speed 100 duplex full autoneg on ethtool -s eth16 speed 100 duplex half autoneg on ethtool -s eth17 speed 10 duplex full autoneg on |
To Configure Jumbo Frames |
Use the ifconfig command to increase MTUs to allow transmission of Jumbo Frames.
