I would say 'no', but man ifconfig would be more authoritative.

Keeping the settings requires the update of the file mentioned by the 
other poster.  And ifconfig *reads* this file, I don't believe it writes 
to it though.
Redhat has their customary system-config-* utils the network flavors 
probably write to that file, but not sure if they work from the command 
line.
