I think that the reason this kind of thing doesn't exist is that it's
more practical to do it on the server.
I.E. monitor the network status and traffic from your server's point of
view.
It's more practical because it's easier to maintain a list of your
servers than to keep Nagios configured to know which switch ports should
be active.
Also set up the switch (should be the default) to send link up/down
traps and have Nagios watch for them so you can quickly correlate your
server network status and know if the switch is the problem when the
server alarms.
