I configure the switch to send traps to the Nagios server (received
using snmptrapd and processed using snmptt), and configure the switch
so that traps are sent if switch-switch links go up/down but not
ordinary switch ports with servers and PCs on.

Other than that, I monitor link bandwidth where it really interests
me, for example on the ports serving our most busy systems and one or
two which link main data centres together.

The usual rule with Nagios parent relationships is that the parent is
the device closer to the Nagios server than the child.  Don't forget
you can have more than one parent if that's how your network is.

Jim
