Subject: Re: [nv-l] Problems loading
Extreme net MIBs and some other as well
It's unlikely
that anyone can give you all the assistance you need just by looking at the
error messages. They would have to look at the MIBs as well, and try to
reproduce the problem. I can give you some general hints and some
suggestions, but I think that your best course of action is to open a
problem to IBM Support and get them to assist you. You can send them
your problem MIBs for analysis, as well as your MIB databases. I am
forbidden to take customer problems directly from the list, but if you open a
problem to IBM Support, then you can get expert help from someone, if not from
me.
General hints:
(1) How to tell an SNMPv2 MIB
from an SNMPv1 MIB.
After the IMPORTS section, an
SNMPv2 MIB starts with a MODULE-IDENTITY clause, while an SNMPv1 MIB does not.
The MODULE-IDENTITY clause does not exist in SNMPv1. That's how
you tell the difference between an SNMPv1 and an SNMPv2 MIB.
(2) Look at the IMPORTS
section in the MIB before you try to load it.
All MIBs start with an
IMPORTS section which tells you what other MIBs you need to load them
properly. Generally speaking, you do not need to load any of the early
RFCs, the ones with numbers lower than 1500 because those constructs are
already built-in to the NetView loaders and browsers. The newer RFC's,
the ones with numbers higher than 1500 you will almost certainly need.
But the number one use for IMPORTS clause is so that you know what other
VENDOR MIBs need to be loaded in order to resolve what's in the one you have.
If you don't get the vendor MIBs mentioned in the IMPORTS section and
load them first, then you will almost certainly get a "left over nodes"
warning message such as the one you posted. That's the typical cause of
that message, that the MIB databases does not have the anchor point for all of
the elements that some other MIB requires. Another reason might be that
the basic definition of the anchor point has a problem, but usually the issue
is a missing pre-req. These latter syntax problems will never be in
RFC's, they will be in vendor MIBs.
Specific
suggestions:
How does this specifically
apply to your situation? The "left over nodes" message is only a
warning. That means that the MIB you tried to load in fact did load.
But you were warned that not all of it could be resolved. If you
did not immediately unload it, then, from that point on however, any other MIB
you try to load will get the same warning message because the loader produces
it while incorporating the new MIB into the entire MIB database. That's
why you see the high line number (185827). The
problem is already in the MIB database, and not in the MIB you are trying to
load; in this case the TOKEN-RING-RMON-MIB.txt, but in some previous MIB
you already loaded. How can you find out what MIB that is?
Each MIB loader has both a
text file and a binary file. The SNMPv1 loader, xnmloadmib, has
/usr/OV/conf/snmpmib (text file) and /usr/OV/conf/snmpmib.bin (binary file).
The SNMPv1/SNMPv2 loader, xnmloadmib2, /usr/OV/conf/snmpv2mib
(text file) and /usr/OV/conf/snmpv2mib.bin (binary file). To find what
MIB is causing your error, browse the text file for that loader and find
out what MIB contains the first clause in the warning message. Locate
the definition for
Left-over node rptrInfoResetEvent ::= { 5 }
(0)
and then scroll up until you
find the keyword BEGIN that indicates the start of the MIB. If you
unload that MIB, then your warning messages should go away. But this
requires care because if you have been ignoring this message and have loaded
many new MIBs already, you may have introduced new dependencies that will
cause new warnings when you unload your problem MIB. Compiling MIBs is
very much like compiling a program. It is best to resolve the first
error you come to rather than to try to continue.
Now based upon what I know
about the native NetView MIB loaders, the fact that this error message
has this peculiar value at the end of each line, "(0)", indicates to me
that the MIB which contains it has a syntax problem that our loader cannot
resolve. Would that be the entityXMIB? You can try using the process
I just outlined to determine that and remove it from the
database.
Finally, I have to say
once again that MIBs are like program source code, and each MIB compiler has
different syntactical requirements depending on how they are built. Just
as some program compilers are more picky about spaces and punctuation, so also
some MIB compilers are pickier than others about the same things. Are
some vendors don't compile their MIBs at all before shipping them. They
just think they have done it right. So there are no automatic tools to
correct MIB syntax. What you need is experience. Which is why a
call to IBM Support is in order when you cannot figure it out for yourself.
You can learn from them.

[nv-l] Problems
loading Extreme net MIBs and some other as
well |
|
Hi all,
I am a newbie to Netview world, so, please, do not hesitate
to correct
me. I have a lot of
problems loading MIBs, most of which are down to
some problems in the MIBs themselves. Some, however, are
not. I have
used a way recomended
on this list to tell if the file is v2 or v1. So
far I have not been able to load any of the v2 files, and
you can se the
output
bellow:
bash-2.05b#
xnmloadmib2 -load
/usr/mibs/standards/TOKEN-RING-RMON-MIB.txt
-replace
Warning: This entry has
no sub-identifier(entityXMIB): On or around line
185827 of the snmpv2mib file.
Warning: The mib description doesn't seem to be
consistent.
Some nodes couldn't be
linked under the "iso" tree.
These
nodes are left:
Left-over node
rptrInfoResetEvent ::= { 5 } (0)
Left-over node rptrInfoHealth ::= { 4 }
(0)
Left-over node rptrResetEvent
::= { 3 } (0)
Left-over node
rptrGroupChange ::= { 2 } (0)
Left-over node rptrHealth ::= { 1 }
(0)
Left-over node
dot1xSuppMaxStart ::= { dot1xSuppConfigEntry 5 } (1)
Left-over node dot1xSuppStartPeriod ::= {
dot1xSuppConfigEntry 4 } (1)
Left-over node dot1xSuppAuthPeriod ::= {
dot1xSuppConfigEntry 3 }
(1).................
I have these leftover nodes more than 1000... I have tried
to load all
v2 CISCO mibs.... I
have tried also all the standard v2 mibs...
If you say that I have to start over, I will do that
gladly...
On the other hand,
below is another one, for Extreme networks. I can not
see any problems with the file. I have tried with the
official one (from
Extreme net)
and the one from ByteSphere's
http://www.oidview.com/mibs/detail.html
bash-2.05b# xnmloadmib2 -load
/usr/mibs/Enterprises/Extreme\ Networks\
Inc/ExtremeWare\ -\ Extreme\ 7.2.0\ MIB/extreme_m1.mib
-replace
Warning: This entry has
no sub-identifier(entityXMIB): On or around line
185827 of the snmpv2mib file.
Error detected while loading MIB File:
/usr/mibs/Enterprises/Extreme
Networks Inc/ExtremeWare - Extreme 7.2.0
MIB/extreme_m1.mib.
This MIB
cannot be loaded until the following problem is
corrected:
Bad format of
optional clauses(}): On or around line 6532
Bad parse of OBJECT-TYPE: On or around line
6532
Mib table is
bad.
Since, I will,
probably have to start changing mibs, do you have any
tools (freeware if possible, we have bought Tivoli Netview
and TEC :))
which could help me,
or some links where I could find the exact
definition for a MIB file (no RFCs please, I have tried,
trust me, I do
not have the time
for that.
I hope that I am not
too picky.
In the end: We are
running NetView 7.1.4 on AIX 5.2L
bash-2.05b$ uname -a
AIX tivoli 2 5 005D6ACC4C00
Thank you all for your patience with this

Have a nice
