the contextEngineID identifies the snmp entity that should process the
request and the contextName tells the agent in which context it should
search for the objects that are requestet in the PDU (an snmpv3 agent
can have multiple objects with the same oid).

Any book about SNMPv3 and the SNMPv3 RFCs should contain a more
detailed/better explanation.

Kind regards,
