SNMPv3 Informs

Inform notifications require two−way communication. Inform messages expect a response. An Inform

notification is essentially a Trap that gets acknowledged by the SNMP application that receives it. The

sending SNMP application will repeat the Inform message until it gets an I got it response from the receiving

SNMP application. In this case, the receiving SNMP agent is authoritative, which means the inform message

should include the Security User credentials and the EngineID of the receiving agent. However, because this

is a two−way communication, it is possible for the sender to discover the Engine ID of the receiving agent.

And because the engineID can be discovered, it is not necessary to specify an engineID in the SNMPTrap

Service's configuration file. It is only necessary to provide security user/credential information in this file and

let the sender discover the engine ID as illustrated here.

Security information for Inform messages is defined using the

createUser

directive in the

snmptrapd.conf

file.
