The code actually notices that the interface went away, but it's not clear when we should simply mark an interface as down versus actually removing it. We should probably define a snmpd.conf token to allow users to specify a timeout (with special values for 'immediately' and 'never').

For example, most recent Linux kernels keep their own internal idea of what the ifIndex is for an interface, so there's no reason for us to keep it around simply for that reason. In fact, this kernel behaviour causes it's own problems, as ppp interfaces that go down and come back up are assigned a new ifIndex by the kernel. We get complaints about this too, as old ppp interfaces don't go away, and new ones keep getting larger and larger ifIndex values. ------------------------------------------------------------------------------ Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.
