SNMP requests are not done in response to failing polls.  SNMP requests are
done for new node discovery and config check.

Polling is done at the interface level. When a poll for an interface times
out, and all retries are exhausted without a response, you should see an
Interface down trap for that interface.  If the box still has other
interfaces which are up, you should see a Node Marginal trap.  When all
interfaces on the box are down, you should see a Node Down trap.

When netview polls a device for status and does not get a response what
happens next?

Does netview then generate a trap or
does it send an snmp request to the device?

I guess what I'm trying find out is let's say there is a router that is
completely out and netview does a status poll but receives no response, is
netview going to generate an interface down trap or something more
critical?
