Hi,
You can delete the whole configuration and put it back this will stop
and restart all the processes.
What you need is a restart command that can be given a part of the
configuration tree that can delete and then put back the
configuration. You can emulate this behaviour by using the save command
to save the config, then delete the config, followed by loading the
saved config.
