Acknowledgements & Credits BEGIN PART 2: =========== @40. ~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." @41. ~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: A. The Open Book: A Practical Perspective on OSI by: Marshall T. Rose ISBN 0-13-643016-3 (c) 1990 Prentice-Hall, Inc B. Open Systems Networking: OSI & TCP/IP by: David Piscitello & A. L.

The UT-SNMP projectgroup --------------------------- description: Currently, we are building version 4 of the UT-SNMP package. In this new version we initialize the PartyMIB by a configuration file(s). The layout of this initialization file is defined and described in the "SNMPv2 Administrative Configuration Proposal" by Dave Perkins and John Seligson (Synoptics). Some projectmembers have made software to create those configuration file(s) in a very convenient manner. The software asks some simple questions and depending on the input generates the initialization file(s). package: UT-PERKINS-1_0.tar.Z programmers: Martijn Visser & Erwin Bonsma. postal: The UT-SNMP projectgroup Tele-Informatics and Open Systems Group Department of Computer Science P.O.

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/ g.

(from Mark Wallace) The comp.protocols.tcp-ip.ibmpc faq had this info on a DOS SNMP monitor package: Downright Speculation SNMP monitor Free Available at file://sun.soe.clarkson.edu/pub/packet-drivers/snmpsrc.zip. Also available at file://enh.nist.gov/misc/snmpsrc.zip, snmpsup.zip,snmpsun.tar_Z. j. from UC Davis (see FTP list in Part 1 ) k. 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. ralex@world.std.com pwilson@world.std.com l. ISODE -- see section 39 in Part 1 of this FAQ B.

MIBS @1. ~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. @2. ~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. Dave Jagoda (dj@netlabs.com) writes to provide ... " ... some useful RFC's that I think might be of general interest (particularly since I think many people don't realize these exist and might try to invent something like these on their own). They all have in common the fact that they are assigned under the mib-2 portion of the tree." RFC1158, RFC1213, RFC1215: mib-2 ( 1 - 11 ) mib-2 ------------------------------------------- In the case of MIB-2 (12), brock@cs.unca.edu writes: In RFC 1229, Extension to the Generica-Interface MIB, the objects in ifExtensions, experimental (6), are defined. In RFC 1239, some experimental MIBs are reassigned to standard MIBs. At that time, the Generic IF objects are reassigned to mib-2 (12). However, RFC 1573 officially "obsoletes" RFC 1229, by defining a new class objects, in mib(30) and mib(31) that replace the the ones of RFC 1229. Also, there seems to be a new RFC -- RFC 1657 -- for mib-2 (15), BGP. ------------------------------------------- RFC1243: mib-2 ( 13 ) appletalk RFC1253: mib-2 ( 14 ) ospf RFC1269: mib-2 ( 15 ) bgp (obsolete?)

[MIB segments?] ---------------------------------- An enterprise MIB is a MIB created by an enterprise [company, etc] to define a set of objects that are related to some product[s] from this enterprise, and that the enterprise agrees to make public so that network managers can use the MIB to manage some products from this enterprise.

The number is 310-822-1511 x239. You'll be asked a few questions and be given you your number. This is faster than e-mail. Please supply: Company Name, Address, Voice Phone, Name of Contact, Contact's Address, Voice Phone, FAX Phone, Email. - You can snail mail: Internet Assigned Numbers Authority USC/Information Sciences Institute 4676 Admiralty Way Marina del Rey, CA 90292-6695 -- Mark Wallace Harris Corporation, Electronic Systems, Melbourne, Florida, USA mwallace@sur3ax.ess.harris.com If you utilize GNU Emacs, a profile is available which makes Emacs set up specifically for ASN.1 editing.

The object or objects used to represent a particular resource 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 mib-2 = 1 which is the global root prefix of every SNMP MIB object. For more details, read: I4B. SNMP, SNMPv2 and CMIP: The Practical Guide to Network Management Standards by: William Stallings @7. ~Subject: What is ASN.1? ------------------- ASN.1 : This is an Abstract Syntax Notation One. ASN.1 is an language used to define the formats of the PDUs that are exchanged by SNMP entities, and also used to defined the objects that are managed thru SNMP. This is a formal language, with a grammar that has been defined in : Information Processing Open System Interconnection Specification of Abstract Syntax Notation ONE (ASN.1). International Organization for Standardization (ISO) and International Electrotechnical Committee, 1987. International Standard 8824. In ASN.1, you can define Modules, which are collections of ASN.1 descriptions, each description referring to an object. Possible objects are types, values and macros. Types can be both simple or constructed, constructed types being based on one or more simple types. Simple types are : Integer, Octet String, Object Identifier, NULL. - Paul Rolland ASN.1 is well defined and explained in three of the books mentioned in this FAQ: From Philipp Hoschka: "I've assembled a number of ASN.1-related internet resources and included them in my homepage."
