To see the state of interfaces...
ifconfig
To bring eth0 back up with the proper settings...
ifup eth0
The problem with what you tried is that ifdown and ifup utilize the interface configurations, but ifconfig takes configuration from command line arguments. So what you did for an interface is like what a wrecking ball does for a house. One cannot demolish a house and then put it back by "undemolishing it". You need house plans to rebuild it.
Using ifdown and ifup work well and take into account all the dynamic configuration (like use of dhcp), related routes, etc. when bringing an interface down and up.
