What is wrong here? What you've shown is a correct operation
as far as I can see. May be you wanted "ifup"/"ifdown" instead
of "ifconfig up"/"ifconfig down"? Former are scripts which parse
"interfaces" file and setup things as described, while latter
are simple commands to bring interface up/down.

PS And consider using "ip addr" and friends instead of venerable
"ifconfig". "ip" command is newer way of operating network
interfaces.
