If you look in /etc/sysconfig/network-scripts/ifup, you'll see that it 
will call /sbin/ifup-pre-local if it exists, before bringing up the 
network interface.

That script also calls .../network-scripts/ifup-post after bringing up 
the network interface, which in turn will call /sbin/ifup-local, if it 
exists, as its last step.

Neither is interface-specific, but they get the interface name passed to 
them, so if you needed to do something different for different 
interfaces, you could.
