• Activate the device.
Based on the type interface being added, issue an
# ifup eth<n>
# ifup tr<n>
6.2.2. Working With the QETH Device Driver
The QETH network device driver supports zSeries HiperSockets, OSA-Express Fast Ethernet,
Gigabit Ethernet (including 1000Base-T), High Speed Token Ring, and ATM features (running
Ethernet LAN emulation) in QDIO mode.
Based on the type of interface being added, the QETH driver assigns one of three base
interface names:
• hsi for HiperSocket devices
<n>
• eth for OSA-Express Fast Ethernet and Gigabit Ethernet
<n>
• tr for Token Ring
<n>
The value is an integer that uniquely identifies the device.
<n>
type, 1 for the second, and so on.
• Load the device driver:
# modprobe qeth
• Create the group device:
# echo <read_device_bus_id>,<write_device_bus_id>,<data_device_bus_id> >
/sys/bus/ccwgroup/drivers/qeth/group
Due to the length of this command, it has been broken into two lines.
• Configure the device.
