Hi,
I am also looking for similar situation in my network.
If parent device went down, then all the devices connected to it will showed up as unreachable. With that my mailbox got full of emails.
So is there any way out for it. What I want is if particular device went down and the devices which went unreachable should come in a Single Email ?
Above all I do not want my general monitoring to get disturbed. If particular device went then there should be email for it in my mailbox.
Any Suggestions....
