Default Re: rfc: snmptrapd as sub-agent

HI,

Thanks for sending the link to the email.

Here is what I believe that you are doing. Please
confirm or correct....

On a system (and there can be 10s of thousands of them),
that right before a notification is sent as an inform,
that the system contacts another system and that system
adds a USM table entry to the agent associated with the
notification receiver (via SNMP sets) (and also adds
an entry in the "to Group" table, and I assume the
VACM access and view tables are already set up and
don't need to be updated). I couldn't tell what security
level you were using. I couldn't tell if you make these
USM and ToGroup entries persistent (and reuse them).

Is it correct that the USM and ToGroup tables will
then contain 10s of thousands of entries?

How often are entries added, removed, or updated
in the USM and ToGroup Tables?

What security level is being used on
a) creating the USM entries
b) sending the informs

How are the keys transmitted to the managed systems
sending the informs (if a security level other than
noAuthNoPriv is being used)?
