Don't really know what your asking.

You can setup a ifstated loop, there are examples on the net and in
ifstated.conf

Or 

If immediate action isn't required or wanted after an unknown event, you
could just use.

ifconfig fxp0 || do something (e.g. ifconfig fxp0 create or /bin/sh
netstart)
ifconfig fxp0 && do something/nothing
ifconfig fxp0 | grep UP && do something/nothing
ifconfig fxp0 | grep UP || do something (e.g ifconfig fxp0 up)
