How can we get address of bonding devices? For example, if I executed
above
^^^^^^^
code on my system, this is what I get:
oops.. I mean aliases.
bond0 device address is: 0x80000203 (128.0.2.3)
bond0:0 => no such device
eth0 device address is: 0x80000203 (128.0.2.3)
This is, ifconfig output:
bond0 Link encap:Ethernet HWaddr 02:00:00:00:01:00
inet addr:128.0.2.3 Bcast:128.0.7.255 Mask:255.255.248.0
inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link
