Re: [Isms] IsmsQuestions on TLSTM/TSM and RFC 5343

Hi Wes,

Thanks for your reply (and also those of Tom
and Juergen).

I understand that RFC 5343 solves the
contextEngineID discovery problem, but
within the last 10 years with SNMPv3
I learned, that most SNMPv3 users do not
understand the authoritative and context engine
ID concepts.

There are also a couple of companies
creating SNMPv3 devices with identical
authoritative engine ID for all instances
of their device. We API developers are then
asked to work around these problems :-(

That's why I thought about simplifying
the SNMPv3 and making the discovery of
a contextEngineID unnecessary if not
required by the command generator.

Nevertheless, I agree that using a single
magic contextEngineID for the local context,
would interfere with proxy applications,
for example.

I will now first finish my implementation
and then make a complete report and analysis
of the result. This will also include using
contextEngineId discovery with USM.

Best regards,
Frank
