What is the different between the authPriv and authNoPriv?
authNoPriv — Authentication, but no data encryption. With this security level, users send SNMP messages that use the SHA key or password for authentication, but not a DES key or AES128 for encryption. authPriv — Authentication and data encryption.
What is engine ID in SNMPv3?
The Engine ID is used by SNMPv3 entities to uniquely identify them. An SNMP agent is considered an authoritative SNMP engine. This means that the agent responds to incoming messages (Get, GetNext, GetBulk, Set) and sends trap messages to a manager. The agent’s local information is encapsulated in fields in the message.
