Refer to your AIX documentation (http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base/aix43.htm , etc.). Gigabit ethernet is sometimes known as "MTU 9000". Per AIX doc: Increase MTU size for the network interfaces. For the Gigabit Ethernet adapter use the device attribute jumbo_frames=yes to enable jumbo frames (just setting MTU to 9000 on the interface is not enough). Richard Sims, BU
