not receive notifications from devices that depend on a device of a top node

Hi
Is there a way to not receive notifications from devices that depend on a device of a top node?
e.g. if I have a switch with 5 devices connected and it gets disconnected, is it possible to receive only a notification from the switch instead of 1 from the switch and 5 from the other devices?
it is useless to receive hundreds of emails when the problem goes back to a single device
Thanks

Yes you can set the parent on each device.

Thanks that worked but sometimes I still get some e-mail from a child device, I think it is due to the polling synchronization: the polling on the child device came before the polling on the parent device, so I get the child e-mail anyway
Is there a workaround?
