2.00.00 FAQ PART 2 of 2:

2.01.00 --CMIP

2.01.01
SUBJECT: What is CMIP?
----------------
   YES, we do need to mention it here!
 
   Paul Rolland writes from France:
 
 "CMIP is the Common Management Information Protocol. It is an OSI
  protocol that has been defined for Network Management. It comes
  together with the CMIS (Commom Management Information Service). 
  This service provides :
    monitoring: in this case, you are using CMIP to gain information,
    control:    you can manipulate objects that you manage,
    reporting:  Managed objects can tell you something wrong is
                happening."
 
2.01.02
SUBJECT: What books should I read about CMIP?
---------------------------------------
   The collected OSI specifications are of sufficient bulk
   to sink a small craft in calm waters.  Start easy:

SUBJECT: What is OMNIPoint?
---------------------------
   "A common approach to the integrated management of
    networked information systems."
 
   In practical terms, a vehicle for helping to bridge
   the standards gap between SNMP and OSI/CMIP so that
   the end user customer can reap the benefits of both.

2.02.00 --Other Network Management Protocols

2.02.01
SUBJECT: What alternatives exist to SNMP?

1) CMIP/GDMO (Common Management Information Protocol/Guidelines for the
Definition of Managed Objects) is an ITU network management protocol.
Requires more resources on client and server to operate than SNMP but
provides a richer and a better object oriented basis than SNMP; still backed
by many telecommunications vendors and carriers but some question its future
now that CORBA has become so popular (see below). Try http://www.itu.int/

2) TL1 (Transaction Language 1) is a Network Element (NE) management
language defined by Telcordia (formerly Bellcore) that is used primarily in
North America in telecommunications equipment. Unlike all the other
protocols I mention here, it is ASCII based and designed to allow text entry
of commands via a "craft" port (EIA232 or X.25 connector) by a machine or
"craftsperson" and responses or autonomous messages to be easily parsed by
machines and read by craftspersons. Try http://www.tl1.com/ or
http://www.telcordia.com/

3) (There is a German NE management protocol that I always forget the name
of; don't know anything about it though.)

[I think you mean QD2, right? It is somehow a light version of Q3.
For more information on QD2, please contact mailto:tssinfo@de.bosch.com

--Frank Fock]

4) CORBA (Common Object Request Broker Architecture) is an object oriented
remote-procedure-call (RPC) protocol. While not designed specifically for
network management, it is now considered a more widely available and less
expensive alternative to CMIP/GDMO for NEs whose management requirements can
not be easily met by SNMP or TL1. Try http://www.omg.org/

5) HTML or XML. Starting to show up in IP equipment, such as network ready
printers. (Try pointing a web browser at a recent HP laser printer if you
have one on your network and see if it doesn't have a web server running on
it, along with an SNMP agent too!)

And then there are proprietary protocols, of which I have a small knowledge
of one or two:

6) TBOS (Can't remember what it stands for! A web search should help; very
simple alarm and control protocol.)

7) Badger and Larse low baud rate serial protocols for control and
monitoring of, for example, microwave sites. Try http://www.badger.com (I
consulted to Badger Technology for a while.)

James Logajan

I wouldn't suggest CORBA is a management protocol (it isn't) or that it
could be used as one.  CORBA is only a spec, not a product, and the
products from the specs vary so much they are often not interoperable.
CORBA is expensive to implement and difficult to manage.

[...]

However, Visual Edge makes a product called ObjectBridge that is a
COM/CORBA bridge that also has an SNMP agent built in, and generates
MIB files for the CORBA objects.  If you have to use CORBA to monitor
applications, as is often the case in UNIX when people try to use Java
for enterprise apps, this product would work well for adding monitoring
capabilities.

DMTF and CIM, and their associated technologies, like WBEM, are your
best bet for alternatives to SNMP.  I know of nothing else that is
industry-wide.

the PartyMIB by a configuration file(s). The layout
of this initialization file is defined and described
in the "SNMPv2 Administrative Configuration Proposal"

Some projectmembers have made software to 
create those configuration file(s) in a very

     "The tkined & scotty network management system
 
     The Technical University of Braunschweig has developed an
     extensible network management platform which uses the
     Tool Command Language (Tcl) as its primary extensions
     language.
 
     The tkined network editor is the graphical user interface
     which integrates applications that are usually written as
     Tcl scripts based on the scotty Tcl extension. scotty provides
     access to SNMPv1 and SNMPv2 and a number of well known
     Internet services like DNS, various ICMP packets, NTP, TCP,
     UDP, SUN RPCs (mount, rstat, portmap) etc.
 
     Applications distributed with the scotty and tkined sources
     include network discovery, trouble-shooting applications, 
     event filter, SNMP MIB browser etc. An experimental MIB
     browser is also available via WWW using the URL:
        
     http://www.cs.tu-bs.de/ibr/cgi-bin/sbrowser.cgi
 
     The SNMP Tcl extension uses a SNMPv1/v2 protocol stack written
     from scratch which was designed to directly support our Tcl
     API. This provides a portable and fast implementation. A brief
     history on SNMP Tcl extension is available using the URL:
        
     http://www.cs.tu-bs.de/ibr/projects/nm/scotty/tcl+snmp.html
 
     Information about the current status of the project, the
     mailing list and the availability of our software can be
     found at:
 
     http://www.cs.tu-bs.de/ibr/projects/nm/tkined/
     http://www.cs.tu-bs.de/ibr/projects/nm/scotty/

     [Editor's note: Holger Trapp has informed me that all of
      the above URL's for tkined & scotty should be replaced by

      http://wwwsnmp.cs.utwente.nl/~schoenw/scotty/

     Another Scotty URL:

     http://starbase.neosoft.com/~claird/comp.protocols.snmp/snmp.html
     has links both to Scotty, generally my favorite tool for this work, and
     snmpy, which is written in Python.  There also are solutions in Perl
     and other scripting languages. [Cameron Laird]

2.10.01.09
     from UC Davis  & Wes Hardaker (see FTP list in Part 1 )

What is it?
----------

  - Various tools relating to the Simple Network Management Protocol
    including:

	* An extensible agent
	* An SNMP library
	* tools to request or set information from SNMP agents
	* tools to generate and handle SNMP traps
	* a version of the unix 'netstat' command using SNMP
        * a graphical Perl/Tk/SNMP based mib browser

    This package is originally based on the Carnegie Mellon University
    SNMP implementation (version 2.1.2.1), but has developed significantly
    since then.

Is it free?
----------

  Yes.  See the enclosed COPYING file for copyright details.  With
  this version only (version 3.4), I'm asking people to send me a
  postcard of your home city, area, or country.  I intend to arrange
  them into a logo, take a picture of them all, and use the picture on
  the ucd-snmp web page.  If you wish to send a postcard, please send
  it to:

			General info
			------------
Subcription/unsubscription/info requests should always be sent to
the -request address of a mailinglist.  In this case, send these
requests to ucd-snmp-request@ece.ucdavis.edu.  

To subscribe to a mailinglist, simply send a message with the word
"subscribe" in the Subject: field to the -request address of that list.

To unsubscribe from a mailinglist, simply send a message with the word
"unsubscribe" in the Subject: field to the -request address of
that list.

Do not send multiple (un)subscription or info requests in one mail.
Only one will be processed per mail.

NOTE: The -request server usually does quite a good job in discriminating
      between (un)subscribe requests and messages intended for the maintainer.
      If you'd like to make sure a human reads your message, make it look
      like a reply (i.e. the first word in the Subject: field should be "Re:",
      without the quotes of course); the -request server does not react to
      replies.

     from pwilson:

"New portable SNMP agent distribution is available under GPL.
We call it snmp95. It is available for anonymous ftp from
          ftp://ftp.std.com/vendors/snmp/snmp95/snmp95.tar.Z

As well as number of other products named xxxx95 it is rather
a transtional product representing current intermediate state
of SNMPv1 -> SNMPv2 transition.

First, let me describe what is there.
 
1. It is bi-lingual SNMPv1/SNMPv2 implementation based on the
   recent drafts, which will change along with draft changes.

2. It includes two agents: base agent which will compile and run
   on all kinds of UNIXes, but without MIB-II and agent which will
   compile and run on SVR4/386 UNIX. Latter one has driver/kernel
   based (Karl are you reading ?) implementation of MIB-II for streams
   based TCP/IP.

3. Long time ago the thing was started from CMU-SNMP code, so it still
   shares common philosophy and some familiar names. At the same time
   basic SNMP library has error detection/reporting added to fully
   support new errors required by SNMPv2. Agent to MIB interface
   is also improved - MIBs can be hooked on the agent as binary modules.

4. The general design philosophy is to have a predictable minimal load
   on the underlying managed system from SNMP agent (e.g. agent does not
   use malloc's) while providing commercial level of capabilities: binary
   extensibility, fully implemented SETs and error-code support.
 
5. Admin/security portion of the code is separated from the rest of the
   code. So, if any new admin models will surface no changes in MIB or
   agent code will be required, unless some creative statistics will
   be stacked in.

6. Code is extremely portable. Practically 99% of system dependent
   code is contained within driver itself. I do not think that it 
   will take more than a couple of days to port it to something else.
   
7. Simple community based admin model codes are provided. An absolutely
   trivial one with base agent and a little bit more sophisticated
   with svr4x86 one.

8. Code is lightly tested in the respect that it will perform gets and
   get-nexts on all variables in MIB-II, supported by underlying system.
   It will also perform SETs on all read-write variables in MIB-II and
   in ipForwardTable, except tcpConnState. What was not tested yet is that 
   phase1 one of SET will reject absolutely all thinkable wrong routes
   without allowing for commit phase to take place: there is practically
   unlimited number of wrong routes. So, we tested against some most evident
   wrong ones but this is not finished yet."

There are several tools you can use. First of all is the ever popular scotty
(TCL/Tk) package for Unix.

The URL for Scotty is:

"sts is an SNMP trap switchboard, which can be configured to
display, log via syslog(8) or redistribute received traps to
other hosts.  The idea is to configure all network equipment
that is capable of generating SNMP traps to send all traps
to sts on a single host, under the assumption that it is
easier to adjust trap handling in a single tool than to
reconfigure a number of network devices whenever the
requirements of local network management change."

Getting started with SNMP on Windows NT

Windows NT comes with an extendible agent. You can install the extendible
agent, and a included MIBII extension, in Network in ControlPanel. Under
the Services Tab, you can press add service. The files should be included
on your CD. I don't think its possible to get the source code for the
extendible.

There are, however, source code available for extension agents. You should
be able to find a document called "Microsoft Windows NT ANMP Agent
Extension", by Steve Rosato, if you search in SDKs, MSDN or maybe
Microsofts Web-pages. This document together with the sample
(Toaster-agent) gives a starting point in developing own extensions. There
are also several extensions available from diffrent vendors.

Both SNMP Agents and Managers on NT (and Win95) use the SNMP API. There are
source code available for a simple manager called SNMPUTIL and SNMPWALK.
Try to search for these.  And of course it's possible to buy NT managers
form diffrent vendors.

ucd-snmp and Windows NT

  "The ucd-snmp applications (snmpget, snmpwalk, snmptrap,
   snmptable...) all work on Windows NT and Windows 95.  The agent,
   however, currently does not.  The agent was originally written for
   the unix operating sytem, and agent's in general are very operating
   system specific, so porting the (or any) agent to an entirely
   different platform, like Windows NT, would be a rather long task.
   The ucd-snmp toolkit has a very extensible agent that allows you to
   remove large sections of code from compilation easily, so porting
   the agent could at least be broken down into sections and tackled
   in small pieces."

Make sure you use the SNMP_malloc and SNMP_free routines. Also make sure
that you allocated (via SNMP_malloc) the varBindList.List memory
sizeof  RFC1157VarBind * # of variables (where # of variables equals

Well, you're in luck.  I finally found out what was going wrong myself.
There's a documented bug in Win95 which means extension agents don't work.
Nice huh? You have to install the winsock 2 update available from the MS
website.  Maybe this should go in the FAQ.  It mentions that SNMPAPI.DLL
is required, but not that you have to get a new version of SNMP.EXE as
well!

You have to do it directly by the windows registry. Microsoft
doesn't provides a tool to do it!!

Open the registry ->  regedit
Go under :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services...
    ...\SNMP\Parameters\TrapConfiguration

Add a key representing the communities you want to support.
Under this key, add string values representing the machines you want
to be in your community.

Go under :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services...
    ...\SNMP\Parameters\ValidCommunities
Add the communities that you which SNMP to Accept request from.
(I'm not sure if this key is used, because the NT tool to add
communities doesn't update this key!!).

you can find the MIBs for NT and related software (IIS...) at

You can find this file on the RK - CD also.

The Win95 MIB should be provided on the Win95 CD in admin\nettools\snmp, but
I don't know if there is a special Win95 MIB.

If you want to test the toaster mib extension agent dll,
you must compile the toaster.mib file with mib compiler, mibcc
(this mib compiler is in NT resource kit CD)
when you compile the toaster.mib,
you must consider the order of mib file.
i think <<mibcc smi.mib lmmib2.mib mib_ii.mib toaster.mib will work>>
and then restart the snmp service and
retest the snmputil.

Hae-Joo Kim

	1) Install the SNMP Agent network service in Windows 95/NT.  (Sounds
like you already did this.)
	2) Register the extension agent in your Window 95/NT registery via
regedit/regedit32.  (Sounds like you did this too.)
	3) If needed, compile the extension agent.  (Using Visual C++ 5.0, I
successfully compiled the toaster MIB as a DLL with a static link to
snmpapi.lib.)
	4) Install the extension agent (i.e. toaster MIB DLL) in the directory
you defined in regedit/regedit32.
	5) (And this is what took me a day to figure out...)  Install
snmpapi.dll in c:/windows.
	6) Restart your agent Windows 95/NT platform.  Your SNMP manager should
now be able to query the "toaster MIB" extension agent under
1.3.6.1.4.1.77.2.

Disappearing MIB Objects

I installed SNMP service on my NT4 w/s and ran perfmon and was hoping to
find the TCP/IP/UDP/ICMP objects to monitor them.. i just cannot find
them..any help why.. the documentation says they should show up!!

Some info I think I should add when i start the snmp service it says this
message :" The procedure entry point snmpsvcGetEnterpriseOID could not be
located in the dynamic link library snmpapi.dll"
But the service starts after that..

--Arni Raghu

This is a very common problem - The problem is that you've added SNMP after
you installed a Service Pack. You need to reinstall a service pack
(preferably Service Pack #3)

SUBJECT: More About CMU SNMP Software
--------------------------------------

2.16.01.01

I've released version 1.11 of the CMU SNMP Library.

	ftp://ftp.net.cmu.edu/pub/snmp  

This version contains a couple of bug fixes.  The most important one
is that it will correctly call the new parser to read the new mibfiles
(mib-v2.txt).

If you use our SNMP library, and wouldn't mind others knowing it,
please send me some mail describing what you are working on, and any
URLs you may have.  I'd like to collect this information and put it on
the CMU SNMP web site.

For examples of how to use this library, check out the snmpapps
collection:

	ftp://ftp.net.cmu.edu/pub/snmp/snmpapps/

An example of using the build-in miniclient can be found at:

	ftp://ftp.net.cmu.edu/pub/snmp/dns/dnscmd/

The main changes are:

Shared Library Support
----------------------

Now has the ability to build a shared library.

New Parser
----------

Added a new parser that will handle SMIv2 (and even some SMIv1) MIBs
without any MIB changes.  This was the #1 complaint about the previous
releases was the inability to use MIBs from within RFCs.  Now you can.

Check out ftp://ftp.net.cmu.edu/pub/mibs for more information on what
MIBs we've used without problems.  (Currently, we're using lots of
MIBs from RFCs, and from Cisco.)

The old parser is still there, so the file /etc/mib.txt will still be
parsed as it is now.  However, if the file /etc/mib-v2.txt (or the
env. var. MIBFILE_v2 is set), that MIB will be read instead.

I believe everybody that uses our software will be happy with the new
parser.

-Ryan

I've released a new version of the CMU SNMP Apps.  They are located
at:

	ftp://ftp.net.cmu.edu/pub/snmp/snmpapps

The major change in this version is the Win32 port.  Included is a
readme file that will tell you how to compile them under Win32 with
the newest CMU SNMP library (1.9).

The CMU SNMP library, available at ftp://ftp.net.cmu.edu/pub/snmp,
will encode and decode SNMPv1 (and v2) packets.  While it has a "C"
interface, the headers will correctly work with C++, and you can use
it there.

It does work in the Win32 environment, and currently comes with a set
of workspaces for Microsoft Visual C++ 5.0.

==ANSWER:

No.  V1.6 is the SNMPv1 package, modified to allow SNMPv2 requests.
It is not based on the 2.1.2 package at all, doesn't come with an SNMP
agent, and doesn't support parties.

Basicly, if you want to write an SNMP app, I'd suggest this library.
But that's just because it's what I'm currently using. :)

If you want an agent and/or the SNMPv2 party stuff, use the library
from ftp://ftp.ece.ucdavis.edu/.

==ANSWER:

UCD started out from CMU 2.1.2. CMU 1.6 is a rewrite
(started from CMU 1.1)that offers an API and the simple
applications (GET, GETNEXT, WALK, SET), but no agent functionality. 
UCD has a reasonably complete (extensible) agent for
many (Unix) operating systems.

Does CMU provide an agent?

===ANSWER:

The CMU SNMP Agent was part of the older SNMP software available via:

	ftp://ftp.net.cmu.edu/pub/snmp-dist/cmu-snmp2.1.2.tar.Z

We currently do not support that agent.  I'd suggest looking at the
UCD SNMP Agent.  It was based on this agent, but is more functional
and portable.

===ANSWER:

Yes.  Before you send each trap, reset the Version field of the
snmp_session structure to the appropriate value.

When the library decodes a PDU, it resets the version of the session
to what it received.  The version is only really used as a sanity
check when encoding V1/V2 specific PDUs.  If you change it before each
send, everything _should_ work.

       Adding MIB to CMU SNMP 1.7

==ANSWER:

Basicly, you need to do the following:

* Make sure it's a v2 MIB (MAX-ACCESS, not ACCESS; etc.)
* Remove MODULE-IDENTITY entries
* Remove TEXTUAL-CONVENTIONs
* Remove DEFVAL entries
* Remove (SIZE()) constraints on anything
   (IE: OCTET STRING and DisplayString)
* Make sure the first quote on all DESCRIPTION strings
  are followed by a space

That's all I can think of offhand.  Typicly, I make these changes, and
then stick the new MIB into the MIBFILE, and see what fails.

I've been placing the MIBs I've modified for use with our parser in:

	ftp://ftp.net.cmu.edu/pub/mibs/

If anybody comes up with other MIBS that have been modified, or
changes that need to be made, please send them to me, and I'll add
them to the HowTo / put them on the FTP site.

i'm trying to get the cmu snmp library and the included tools to work
with my cisco router. as far as i only use the included mib.txt
everything works fine. but i also would like to look at the private
parts of the cisco mib. therefor i wanted to include cisco mibs into
the mib.txt file. but i haven't succeeded so far.

there are a lot of parse errors. i even downloaded the modified cisco
mibs from cmu.edu but didn't work either.

what is the correct way to do this? what cisco mibs to use? just
append the mib to the end of the default mib.txt?

i've read the faq and found no clue. i would be very glad if someone
could give me pointers to get this to work. better even: a working
mib.txt with cisco's mibs already included.

--Ralph Schmieder

==ANSWER

The CMU code has a miserable parser when it comes to MIBFiles.

If you want some MIBs that will work with the CMU code, check out:

	ftp://ftp.net.cmu.edu/pub/mibs

This contains the MIBs I've modified to work with our code, as well as
a script to process them into something usable.  Check out the readme
for more info.

This site contains lots of cisco mibs.

-Ryan Troll

2.16.01.09

Hey! Where's the Documentation?

==ANSWER
The only true documentation for the CMU SNMP Library, aside from the
manpages, are the programs written using it.  The examples I'd suggest
are:

* The SNMP Apps collection (ftp://ftp.net.cmu.edu/pub/snmp/snmpapps)

* The BIND SNMP Agent (ftp://ftp.net.cmu.edu/pub/snmp/dns)

* DNSCMD: A small program to fetch data from the BIND SNMP Agent
(ftp://ftp.net.cmu.edu/pub/snmp/dns/dnscmd).

DNSCMD uses the snmp-mini-client, so it should be a good example.

Some of the other stuff in the ciscotools directory
(ftp://ftp.net.cmu.edu/pub/snmp/ciscotools) may use it as well, but I
don't remember.

I don`t know if it will solve your problem, but check this
URL: http://www.redpt.com

The product is called SNMP QL. It allows you to do SQL
queries on an SNMP MIB. 

Benoit Legare

If you want a lot of versatility in the use of enterprise MIBs,
as well as some fun, try SnmpQL from Redpoint Software
(http://www.redpt.com) .  It is an ODBC driver that reads SNMP
data as a database.   The ODBC driver setup has a built in MIB
compiler, and it ships with several MIBs.  Imagine tying in
SNMP Gets and/or Sets with an Excel spreadsheet, Access database,
etc.  It's a totally different approach than SNMPc or HPOV, but
it will give you some creative ways to use the NT enterprise MIBs
as well as the MIB-II structure.

I've played around with lots of SNMP code, most of it freely available. I've
found the best for Solaris 2.5.1 to be from MIT. It compiled without error and
the code was very clean, if a little too elegant. You can get it from
ftp://mercury.lcs.mit.edu/pub/snmp. However, documentation is thin on the ground.
I spent a couple of days with the code and it taught me a lot more than anything
else. I'm successfully building agents to monitor our remote applications and
databases with it. (If you need help getting started I'll send you the code I
have added so you can get a general idea)

It took me ages to crawl up the learning curve for SNMP. Everything seemed too
complicated in the beginning, and the FAQs were not all that much use. However,
I found a book that helped me a lot. [Total SNMP 2nd ed. (1998) Sean Harnedy

Data Collection Applications for SNMP

"Take a look at SNMX from WWW.CPRO.COM. [Note: See below]  This is a freeware,
very powerful SNMP scripting language.  It has some graphing capabilities built

tool to extract the SNMP variable values you are interested in, and then
using some other tool (Access, Excel, etc) to do your analysis."

May be you would like to try AGENT++, which is actually a
very _simple_to use C++ API based on SNMP++.

It offers even a simple way to create SNMP tables.

See http://www.fock.de/frank/english/agent++src for details.

AGENT++, examples, and documentation can be downloaded from there.
AGENT++ can be used with Linux, Digital Unix 3.2/4.0, Solaris 2.5.1/2.6.
Porting it to Windows NT should be easy...

Frank Fock

"I downloaded AGENT++ from Mr. Frank Fock's web site last week and ported it
to NT.  Now it can be used to write NT Extension Agents.
You can visit http://www.fock.de/frank/english/agent++src/ to see the

SNMP++ -- An SNMP API Class Library:

"Try SNMP++ from http://rosegarden.external.hp.com/snmp++!

"SNMP++ Revision 2.5 
===================================================================
I am pleased to announce the completion of the new SNMP++
specification. Over the last year SNMP++ has gone from a version
1 specification, which was presented at a Birds-of-a-Feather at
Networld-Interop '95, to the currently available 2.5 revision. The new
specification is freely available on the following FTP server. 

Where to Find the New Specification and Header Files:

             /pub/snmp++/include  *.h         (C++ class definitions)

Intent:
-------------------------------------------------------------------
The intent of the publication of this specification is to make 
SNMP++ an open specification as a C++ based SNMP API and as a C++
extension to WinSNMP. All developers are encouraged to review the 
specification and all comments and suggestions are welcome. 

What is SNMP++:
-------------------------------------------------------------------
SNMP++ is a set of C++ classes which provide SNMP services to a
network management application developer. SNMP++ is not an additional
layer or wrapper over existing SNMP engines. SNMP++ utilizes existing 
SNMP libraries in a few minimized areas and in doing so is efficient
and portable. SNMP++ is not meant to replace other existing SNMP APIs
such as WinSNMP, rather it offers power and flexibility would otherwise
be difficult to manage and implement. SNMP++ brings the Object Advantage
to network management development.

2.30.00 --The SNMP MIB (Management Information Base)

2.30.01
SUBJECT: What is a MIB?
-----------------
  A collection of objects which describe an SNMP managable entity.  
 
  An Important Note: There IS ONLY ONE SNMP MIB.  All these other
  "MIBs" which are cited herein are extensions to *the* SNMP MIB.
  Popular usage and strict definition do not agree on this point, so
  be careful in how and when you talk about the plural of MIB.
 
"Most people, when first starting to learn SNMP, believe that the MIB is a
database/datastore.  It is not.  The MIB does not contain data.  Nor does
the MIB retrieve data from your monitored product."

"When a network manager wants to learn about your node, be it hardware or
software, he must have some way of determining what information is available
to him, and what it means.  This is where the MIB comes in.  The MIB is not
a database.  It is a way of logically grouping data so that it is easily
understood by all.  When you design a MIB, you define and describe the
components of your product.  You also define and describe the data-objects
which the network manager would be interested in.  When building your MIB,
you logically place the data-objects within the product components that you
previously defined.  You now have a description of your product, and the
data-objects which a network manager may request.  At this point, you have a
simple MIB.  Note that your product is not running.  There are no values in
the MIB.  Only a description of each object.  And yet your simple MIB is
complete.  A network manager could look at it, and gain a basic
understanding of your product.  He could also determine what specific
data-objects he would like to query; after your product is running, and SNMP
enabled, of course.":

"The MIB compiler does not 'generate data'. The MIB file is still in the
same form that it was written in.  It is an ASCII text file, written in
SMIv2 syntax."

Wallace Gaebel
 
2.30.02
SUBJECT: What are MIB-I and MIB-II
-----------------------------
  MIB-I was the first SNMP MIB accepted as standard.
 
  MIB-II added some much-needed objects, and has become
  the standard SNMP MIB.
 
  Note that SNMPv2 expands upon MIB-II with new groups
  and objects, and is therefore not MIB-II but includes
  MIB-II. See below for more about SNMPv2.

On the following, "how can you convert a MIB in the SMIv1 format
to one in the SMIv2 format", the answer is that you cannot do this
mechanically. This is because there is more information content
in the SMIv2 format than the SMIv1 format. You can do much of
the work with a text editor, but not all. The process is covered
on pages 206-211 in "Understanding SNMP MIBs" by perkins and
mcginnis, and in RFC 1908 pages 1-6.

I don't know if it's still in service, but try to send your v2 mib
to following address:

mailto:mib-v2tov1@simple-times.org

[Editor's note: URL reported obsolete.
Mike Heard suggests "Try mailto:mib-v2tov1@dbc.fv.com"]

About Counter64 objects, there is no possible translation. You
should suppress them from the mib before sending it.

Olivier Miakinen


64-bit counters are not supported in SMIv1 nor are they supported in
SNMPv1 protocol. RFC 2089 covers the behavior of bi-lingual SNMP agents.

[post edited here]

The best approach for now is to NOT use the data type of Counter64 in
defining a new MIB object, and instead define two MIB objects.
One object is the low 32 bits of a counter value and the other object
is the high bits of a counter value. This places a burden on SNMP
applications, but is the best approach to be used until the high
capacity issue is addressed by the IETF SNMP community.

The format of MIB modules is independent of the protocol except for
objects that have data type of Counter64. This type is not supported
in the SNMPv1 protocol. So you can implement RFC 2233 using the SNMPv1
protocol, except for the Counter64 objects. RFC 2089 provides you with
information about implementing a bi-lingual agent.

If your tools support MIBs only in SMIv1 format, you can convert
them from the SMIv2 format to the SMIv1 format with MOSY and SMICng.
(I would suggest that you get a license for SMICng from SNMPinfo
at http://www.snmpinfo.com.)

David T. Perkins

2.30.04.03

You can use mosy to convert MIBs. However, mosy is not doing a very
good job in keeping things readable. It will also simply abort if it
encounters things like Counter64 object types in SMIv2 MIB modules.
Mosy is freely available.

There is a free embeddable SMI parser library package called libsmi
which includes a program called smidump. The smidump utility can
output SMI MIB modules in various formats such as SMIv1, SMIv2, SMIng
and mosy. Future versions will also support CORBA IDL and OID files
(JIDM mappings) as well as various ASCII formats to be used by humans
to analyze MIB modules.

Finally, you can use the SMICng compiler written by Dave Perkins. This
is a commercial product and probably the best compiler you can get
right now. (I am sure there are more commercial products you can use
that I do not know about.)

These are the top level OIDs. From here it gets very detailed. I have

The first two bytes are the year (0x07CD = 1997)

	8th byte is "deci-seconds"

	indicating direction from UTC.

	10th byte is hours from UTC.

	11th byte is minutes from UTC.

This problem would be much easier to figure out if you
provided the MIB definition. There is no one standard
format for storing date/time values.
 
The hex value 07cd in decimal is 1997.

The hex value 002d0600 could be the number of nano seconds, but
you can only determine this by reading the MIB definition.

In SNMPv1, there is no "automated" way of "discovering" what MIBs an agent
supports, so, yes, you would have to query something in each MIB module to
verify it (not that this would verify that the agent supported everything in
these modules).  I'm not sure what the difference between your two questions
was, though, since the only thing different seems to be that you used the word
"dynamically" the first time.  This, unfortunately, does not make any sense, as
everything in SNMP is more-or-less "dynamic".

In the now historical (some say hysterical ;-}) SNMPv2, they introduced a
mechanism which is being carried forward to the now-proposed SNMPv3: agent
capabilities statements and other MIB techniques for defining explicitly what
groups of attributes an agent supports.  These features are not yet widely
supported, nor is it clear exactly what role they will play or how solidly they
will be implemented.

Is there a standard way to represent a float as an attribute in a mib ?
The problem I see with an OCTET STRING or DisplayString is  that
in ascii text
	1.5 < 1.50
hence any comparisons may be mistaken. The only other way around
it that I see is to make every float item actually 2 items as such:
	float_val intenger
	float_exp integer
where 1.5 would be written as 15x10^-1 and
float_val = 15
float_exp= -1

However this seems extremely combersome. There has got to be a better
way.

--Randy Sharpe

Not in the spec or in the V2/V3 spec.  No way to create floats that are
universally understood as floats.  RFC1902 takes away the old opaque
declaration that possibly could have been used.  We are looking forward
to Counter32, Counter64 and Integer32 to carry numbers.  What do you
need to float?

This is a FAQ about counters.
The basic question is "Can counters be 'reset'." The answer is no, not
ever. If not, then how can the number of occurrences be obtained?
Answer, you obtain the value of a counter at the first of a time
interval and then at the end of a time interval, and you subtract.
Note, you must also accomodate for counter rollover and counter
discontinuity.

For a short description of counters, see

SUBJECT: How can I change a published MIB?

RFCs 2578-80 describes the allowed changes that can be made to MIB
modules. Changing the name of descriptors in "published" MIB modules
is not allowed. See section 10 of RFC 2578. (Unfortunately, this
section does not say "descriptors cannot be changed" directly. It
says this in a roundabout way with the last two sentences in
section 10.2).

[...]If the MIB module has not been published, then you can modify
it as much as you want. If it has been published, and the errors are
recognized soon, then you can modify it. However, if the module
has been available for some time and has been made widely
available, then you probably have to live with the problems.

David T. Perkins

2.38.01
SUBJECT: How unique must MIB variable names be?

1) OIDs are unique identifiers for all-space-and-time. An OID value
   is an ordered sequence of nonnegative integers that contains at
   least two members with the value of the first member restricted
   to 0, 1, or 2, and the value of the second member restricted to
   0 to 39 if the value of the first is 0 or 1. SNMP calls members
   of the sequence sub-identifiers. SNMP restricts an OID value
   to have at most 128 members, and no member can have a value
   greater than 4G-1 (4294967295).

2) For convenience of people, a label can be associated with
   each member of a sequence. Additionally, there are "well
   known" labels for OID values. SNMP reccognizes only
   "ccitt", "iso", and "joint-iso-ccitt" as well known
   labels for the first member in a sequence.
 
3) There can be multiple labels associated with an OID value!
   (Few SNMP utilities can cope with this.)

4) OID values in SNMP messages are sequences of integers. A
   sequence of labels is never used.

5) Most items defined in SNMP MIB modules are identified by
   an OID value. The exceptions are TRAP-TYPES defined in
   MIB modules in the SMIv1 format and textual conventions -
   either defined with a type assignment or TEXTUAL-CONTENTION
   construct.

6) All items defined an a MIB module have a label, which is
   called a DESCRIPTOR by the SMI. The descriptors for all
   items defined in a MIB module MUST BE UNIQUE. MIB modules
   are a somewhat arbitary scoping mechanism for definitions.

7) The SMI further restricts descriptors defined in MIB modules
   found in standard track documents to be unique. However,
   there is no such restriction on descriptors in non-standards
   track documents or descriptors in MIB modules created
   by enterprises. The SMI requires that MIB module names
   found in standards-track documents are unique. However,
   no such restriction applies to MIB modules created
   by enterprises.

8) People generally perfer to identify items by descriptor
   value instead of a sequence of nonnegative integers.
   However, for each example of identification by descriptor,
   a counter-example can be given that shows that the
   identification is ambiguous. For example, a single
   descriptor is not globally unique. A descriptor
   qualified by a MIB module name is not unique because
   MIB module names are not globally unique. A
   sequence of descriptors is not globally unique
   because the descriptors for all the children do
   not have to be unique.

Only an OID value written as a sequence of numbers is unique.

SUBJECT: What is the SMI?

"In order for the MIB to serve the needs of a network-management

    must be the same at each node. [...]
 
 2. A common scheme for representation must be used to support 
    interoperability."  -  William Stallings, op. cit. below
 
In both Internet and OSI network management these two objectives
are met by a common structure of managment information (SMI)
which is defined in RFC 1155.  The SMI is the specification
for the tree of MIB objects which which provides a means of
associating a common numerical identification code for a
given object.
 
The top of the SMI tree is the familiar mapping:
 
iso = 1
   org = 3
      dod = 6
         internet = 1
            mgmt = 2

Good index design is one of the harder aspects of MIB design.

In the good old days of SMIv1, all indices were read-only columns
in the table where they were used. Then MIB designers started
using existing indices in new tables under certain situations.
Then SMIv2 was created that specified two important changes.
It introduced the AUGMENTS clause for tables that had a
one-to-one relationship between rows, and specified that the
usual case for access of indices is "not-accessible".
Then MIB designers went sort of crazy with specifying indices.

There is a white paper on the SNMPinfo site (www.snmpinfo.com)
that describes inter-table indexing. Some MIB designers think
it is too strict. However, if you follow it, your indexing
will always be valid.

you need an ASN.1 compiler. Also, do not fall for the believe that
you need an ASN.1 compiler for processing MIB modules.

Whether one or not a asn.1 compiler is free does not matter, because
you really do not need one!

Stallings has: "2's complement representation with the minimum number of
octets."

That would be 02 01 FF, where 02 is the type tag, 01 the length, and FF the
value

2.50.02
SUBJECT: What is the Maximum Size of an SNMP Message?

"The limit on the message size is the minimum of the maximum that the
receiver can process and the maximum that the sender can generate.
The minimum can be no smaller than 484 octets.

A practical maximum is the size that can fix in a UDP message that
does not cause IP fragmentation. This is around 1200 octets on
Ethernet networks. 

Many networks use UDP messages that are around 4K octets, even though
IP fragmentation occurs. Going over routed connections where you
might get packet loss, you would probably not want to have fragementation."

SUBJECT:    A Special, Personal Thanks
            --------------------------
My meager, threadbare knowledge of SNMP and SNMPv2 would be
all the more so except for the patient attention of
Jeff Case and Steve Waldbusser.  These two fellows are
not only masters of their craft, they are also true
gentlemen in every sense of the word. My gratitude.
