Sorry, It was very late in the night when I wrote my posting
and effectively my exemple was wrong.
ifconfig eth0 down , drop down the interface and it's effectively normal
(Thanks you Alexey !)
The good is example is :
ifconfig eth0:0 192.168.1.1
ifconfig eth0:1 192.168.1.2
ifconfig eth0:1 ----> Drop down eth0:1 AND eth0:0 too.
And sorry for my bad english....
