# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 02:00:00:00:00:01
inet addr:192.168.70.87 Bcast:192.168.70.255 Mask:255.255.255.0

Note that the
HWaddr
field in the first line of the
ifconfig
command output. The value after that must
be added to the
ifcfg-eth1
file. Add a line like the following to that file:
HWADDR=02:00:00:00:00:01
Now
ifcfg-eth1
looks similar to the following:
# IBM QETH
DEVICE=eth1
HWADDR=02:00:00:00:00:01
BOOTPROTO=static
IPADDR=192.168.70.69
NETMASK=255.255.255.0
ONBOOT=yes
NETTYPE=qeth
SUBCHANNELS=0.0.0600,0.0.0601,0.0.0602
TYPE=Ethernet
Check the routing for the new interface:
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.70.0 * 255.255.255.0 U 0 0 0 eth1
9.12.20.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
default pdlrouter­if5.p 0.0.0.0 UG 0 0 0 eth0
Verify your changes by using the
ping
command to ping the gateway:
# ping ­­c 1 192.168.70.8
PING 192.168.70.8 (192.168.70.8) 56(84) bytes of data.
64 bytes from 192.168.70.8: icmp_seq=0 ttl=63 time=8.07 ms
If the default route information has changed, you must also update
/etc/sysconfig/network
accordingly.
22.6.2. Quick Reference for Adding Network Devices
There are several basic tasks for adding a network interface on IBM System z.
• Load the device driver.
• Create the group device.
• Configure the device.
• Set the device online.
