In order to use SNMPv3, it's necessary to know the "engineID" of the agent (or strictly speaking, the "authoritative SNMP engine" - which is the agent for GET* and SET requests). One way to do this is to specify the engine ID explicitly (e.g. via the -e command line option). A number of other SNMP toolkits work this way. But the Net-SNMP code attempts to probe the remote agent to discover this value, by sending a request without the engineID in place. This request will fail, but the response that comes back includes the engine ID (and possibly the boot count/uptime values as well). The client can then re-send the request including this information, and hopefully the request should then succeed.
