thanks for your answer, jaiber john.

I have another cuestion I beg an answer to:

if i am implementing an agent and a manager what is better, (1) to open and close a SNMP session for each PDU or (2) to open the session at the benining, and close it at the end.

thanks a lot.

Hello,

This is the first time I'm answering a question ;-). Experts please correct me if I'm wrong. To my understanding, there is no concept of "session" (similar to telnet, ssh, etc) because:

1. SNMP is a UDP-based stateless (request <-> response) protocol, and 2. Each PDU is supposed to have authorization information, if any. Essentially the Agent is not needed to keep track of client-connections.

But there are confusing similarities. Some SNMP libraries and SDKs provide session APIs. Between NetSNMP Agent and an AgentX subagent there is a session.

There's a memo draft http://www.potaroo.net/ietf/idref/draft-hardaker-snmp-session-sm/ that attempts to address this.

 HTH,
Jaiber John

Hello !!!!

I am finishing my tasks with NET-SNMP. These tasks are a part of my thesis.
In this state, a doubt arises. It is almost a philosophical one.

Knowing SNMP is not oriented to conexion, what is exactly a SNMP session?

Perhaps you could think it is a silly quiestion, and perhaps it is, but I
can't find the answer and it is important for the documentation of my
project.

Could somebody clarify this concept (SNMP session) to me? Could you tell me
what does the opening and closing of a SNMP session involve exactly?

Thanks a lot to all.
