Re: Traps and frequency

I agree with you completely.

But my boss doesn't. :-)
I tried to explain him to meaning of synchronous (snmp getnext) and
asynchronous (snmp trap or informs) notifications, but they "explained" me
that they didn't even needed snmp access to the agent. They had configured
the monitor software (open view) to only receive traps.

Moving along...
OK. I will forget my initial suggestion as it is bad engineering. So I have
another question.

Is it right to trust snmp-v2 informs to have a certain degree of trust that
the message was received?

Many thanks in advance,
José Martins
