To Configure Jumbo Frames in a Linux
Environment
1. Ensure that the ixge software is installed.
2. Plumb the Sun 10-Gigabit Ethernet PCI-X interface:
# modprobe ixge
# ifconfig eth2 xxx.xxx.xx.xxx up
# ifconfig eth2 mtu 8170
where
xxx.xxx.xx.xxx
Setting ixge Driver Parameters
You can set the ixge device driver parameters in two ways:
Using the ndd utility
Using the ixge.conf file
If you use the ndd utility, the parameters are valid only until you reboot the system.
This method is good for testing parameter settings.
To set parameters so they remain in effect after you reboot the system, create a
/platform/sun4u/kernel/drv/ixge.conf file and add parameter values to this
file when you need to set a particular parameter for a device in the system.
Setting Parameters Using the ndd Utility
Use the ndd utility to configure parameters that are valid until you reboot the
system. The ndd utility supports any networking driver that implements the Data
Link Provider Interface (DLPI).
The following sections describe how you can use the ixge driver and the ndd utility
to modify (with the -set option) or display (without the -set option) the
parameters for each ixge device.
= the IP address of the interface.
