I think we are talking about dependencies in different ways. ;)  If switch2 
is wired through switch 1 with a cross-over cable, it is in many ways 
dependant on switch 1 for general functionality, which is the type of 
dependency I thought you were talking of in your diagram.  Yes, you get 
proper parent/child relationships in relation to Nagios, but you don't get 
overall network dependencies is my point.  Anyway, if you can specify what 
switch a given Nagios server is connected to, with everything else having 
its parents defined, then Nagios should be able to easily build the 
parent/child maps from its point of view, regardless of where it is 
attached into the network.
