Short answer: this is perfectly normal. What happened was that an IP address was added to the interface without a differentiating label.
Believe it or not, the "ifconfig" application is strongly discouraged because it has a tendency to dramatize situations like this. It would probably have been removed years ago if not for legacy support.
Anyway, if you want to understand a bit more about what is happening, take a look at this iproute2 documentation. They explain that although all alias addresses are secondary addresses, the inverse is not necessarily true.
Then try the following:
Code:
[root@uscltest2 ~]# ip addr show dev eth0
[root@uscltest2 ~]# ip addr add 10.200.218.86/24 broadcast 10.200.218.255 dev eth0
[root@uscltest2 ~]# ip addr
[root@uscltest2 ~]# ifconfig
[root@uscltest2 ~]# ip addr add 10.200.218.87/24 broadcast 10.200.218.255 label eth0:alias dev eth0
[root@uscltest2 ~]# ip addr
[root@uscltest2 ~]# ifconfig
You will notice that after the first add, the output of "ip addr" showed the address, but the output of "ifconfig" did not. Additionally, when you added a label the second time, the output of "ip addr" still shows the address, but the output of "ifconfig" also show our new label. (which only says "eth0:alias" because we told it to - it could literally be anything)
After this little demo, reset things to normal:
Code:
[root@uscltest2 ~]# ip addr del 10.200.218.86/24 dev eth0
[root@uscltest2 ~]# ip addr del 10.200.218.87/24 dev eth0

Hi All,

aoe-stat
aoe-stat(8) System Manager's Manual aoe-stat(8)NAME
aoe-stat - print aoe device status report
SYNOPSIS
modprobe aoe
aoe-stat
env sysfs_dir=/sys aoe-stat
DESCRIPTION
The aoe-stat script collects information on ATA over Ethernet devices from sysfs.
For each AoE device the kernel has discovered, there is one row in the script's output. Each row has the following columns.
devicename
The device name is of the form eX.Y,
with X being the AoE device shelf address, and Y being the AoE slot address.
size The size of the AoE device is in gigabytes (billions of bytes).
ifname The network interface name is printed in the third column.
payload
The number of bytes read from or written to the storage target in each AoE packet appears in the fourth column, unless the aoe
driver does not export this information.
status The device status is in the last column. Possible values are up, down, and down,closewait. The "up" status means the aoe driver
considers this device ready for I/O. The "down" status means the opposite. The "down,closewait" status means that some software
still has the device open, and when this straggler closes the device, it will enter the "down" state.
ENVIRONMENT VARIABLES
If the sysfs_dir variable is set in the environment, it will override the default location where aoe-stat will look for sysfs, namely
/sys.
WARNINGS
If the minor device number of a device node does not match that of its namesake, aoe-stat will print a warning as shown below.
nai:~# aoe-stat
e0.3 0.104GB eth0 up
e0.4 4398.046GB eth0 up
e20.0 1000.215GB eth0 up
e42.0 2000.431GB eth0 up
aoe-stat Warning: device node /dev/etherd/e45.1 has wrong minor device number
e45.1 1152.874GB eth0 up
Using such a device node is dangerous, because its name doesn't match the actual device that you would be reading from and writing to.
Such a broken device node should be removed. Device nodes are created by udev or (on systems without udev) by aoe-mkdevs.
EXAMPLE
In this example, the root user on a host named nai loads the aoe driver module and then prints a list of all the available aoe devices.
Then he remembers to bring up the storage network interfaces, does an AoE discovery, and prints the list again. This time the list shows
all the devices in shelf seven.
nai:~# modprobe aoe
nai:~# aoe-stat
nai:~# ifconfig eth3 up
nai:~# aoe-discover
nai:~# aoe-stat
e0.0 10995.116GB eth0 up
e0.1 10995.116GB eth0 up
e0.2 10995.116GB eth0 up
e1.0 1152.874GB eth0 up
e7.0 370.566GB eth0 up
