Creating a virtual interface on opensuse11

• a normal network interface can be queried via the command ifconfig
  

opensuse01:~ # ifconfig

============================================

• To add the virtual interface.

ip addr add 192.168.80.135/24 brd + dev eth2 label eth2:1

• ifconfig again to the command prompt will display this

eth2:1 Link encap:Ethernet HWaddr 00:0C:29:4F:74:C5

inet addr:192.168.80.135 Bcast:192.168.80.255 Mask:255.255.255.0
