My 2 cents:
1) What is the compatibility/uncompatibility between SNMP V1 and SNMP V2C
The problems with SNMP V1 and V2 are largely due to political and academic
differences among the members of IETF who could not agree on a standard of
management. They disagreed about the usefulness of traps or event-driven
notifications and they disagreed about the need for security and how it should
be implemented. They also couldn't agree on the many new constructs for MIBs.
The result was that most vendors kept their trap architecture despite the fact
that V2 does away with it and substitutes new categories of things called
notifications and reports. I don't know of any vendor implementing these. The
issues with security were so hotly debated that they were revised several times,
and so most vendors, unable to keep up with such academic wrangling, simply
opted not to support it at all. And finally, when the final standard for MIB
constructs turned out to be so different from the draft, some vendors were left
with a V2 MIB compiler that did not support all the new things. That is where
NetView is and why it has two of them. It's V2 MIB compiler does not yet
support all V2 constructs and NetView itself does not support any V2 security
nor V2 event reporting. This is not generally a big problem because no
vendors I know of support anything but the MIB constructs and most offer a V1
version of their V2 MIBs which can be used with NetView's snmpCollect, Ruleset
editor, and so on.
If you want details on this, I recommend you do some reading. My favorite
is Understanding SNMP MIBs by Perkins and McGinnis (Prentice-Hall, 1997).
2) Is Netview able to manage SNMP V2 agents, or what is needed to insure such a
compatibility
Yes, it does so now. (Where have you been?) But you will have to get the
V1 versions of their MIBs and load those if you want snmpCollect to gather data
on MIB constructs not in V1, or you have to edit the snmpCol.conf and
mibExpr.conf file by hand.
3) What is the time table for Netview migration to SNMP V2 or V3
Migration? It is unlikely, given what I have said, that NetView will ever
support all of V2, though you can bet that more work will be done on improving
the V2 compiler in releases following 6.0. But there are no announced
timetables for any feature in any IBM / Tivoli product. When new support is
added it will be announced.
The reason I have called this "my two cents" is that I don't want to be
bombarded or flamed with responses about how NetView not currently supporting
this or that feature of SNMP V2 or even SNMP V3 is holding up some project any
reader may I have. I do not control development of this product nor its
delivery schedules. As I have said many times, you can send your requirements
to netview@tivoli.com, or if that is not formal enough for you, you can contact
your marketing rep or open a problem to Support and ask them to open you an
enhancement request. That is how you influence NetView development.

Hi forumers,
I'm sure this question has already been posted several times, but as I'm quite
new on this forum, I have not seen it for the time being.
1) What is the compatibility/uncompatibility between SNMP V1 and SNMP V2C
2) Is Netview able to manage SNMP V2 agents, or what is needed to insure such a
compatibility
3) What is the time table for Netview migration to SNMP V2 or V3
Thanks for any reply
