        Remote Network Monitoring MIB Protocol Identifier Macros

Status of this Memo

   This memo provides information for the Internet community.  It does
   not specify an Internet standard of any kind.  Distribution of this
   memo is unlimited.

Abstract

   This memo contains various protocol identifier examples, which can be
   used to produce valid protocolDirTable INDEX encodings, as defined by
   the Remote Network Monitoring MIB (Management Information Base)
   Version 2 [RFC2021] and the RMON Protocol Identifier Reference
   [RFC2895].

   This document contains protocol identifier macros for well-known
   protocols.  A conformant implementation of the RMON-2 MIB [RFC2021]
   can be accomplished without the use of these protocol identifiers,
   and accordingly, this document does not specify any IETF standard.
   It is published to encourage better interoperability between RMON-2
   agent implementations, by providing a great deal of RMON related
   protocol information in one document.

   The first version of the RMON Protocol Identifiers Document [RFC2074]
   has been split into a standards-track Reference portion [RFC2895],
   and an "RMON Protocol Identifier Macros", document (this document)
   which contains the non-normative portion of that specification.

1.  The SNMP Network Management Framework

   The SNMP Management Framework presently consists of five major
   components:

    o   An overall architecture, described in RFC 2571 [RFC2571].

    o   Mechanisms for describing and naming objects and events for the
        purpose of management. The first version of this Structure of
        Management Information (SMI) is called SMIv1 and described in
        STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
        1215 [RFC1215].  The second version, called SMIv2, is described
        in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
        STD 58, RFC 2580 [RFC2580].

    o   Message protocols for transferring management information. The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [RFC1157]. A second version of the
        SNMP message protocol, which is not an Internet standards track
        protocol, is called SNMPv2c and described in RFC 1901 [RFC1901]
        and RFC 1906 [RFC1906]. The third version of the message
        protocol is called SNMPv3 and described in RFC 1906 [RFC1906],
        RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

    o   Protocol operations for accessing management information. The
        first set of protocol operations and associated PDU formats is
        described in STD 15, RFC 1157 [RFC1157]. A second set o
        protocol operations and associated PDU formats is described in
        RFC 1905 [RFC1905].

^L
RFC 2896                     RMON PI Macros                  August 2000


    o   A set of fundamental applications described in RFC 2573
        [RFC2573] and the view-based access control mechanism described
        in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo does not specify a MIB module.

2.  Overview

   The RMON-2 MIB [RFC2021] uses hierarchically formatted OCTET STRINGs
   to globally identify individual protocol encapsulations in the
   protocolDirTable.

   This guide contains examples of protocol identifier encapsulations,
   which can be used to describe valid protocolDirTable entries.  The
   syntax of the protocol identifier descriptor is defined in the RMON
   Protocol Identifier Reference [RFC2895].

   This document is not intended to be an authoritative reference on the
   protocols described herein. Refer to the Official Internet Standards
   document [RFC2600], the Assigned Numbers document [RFC1700], or other
   appropriate RFCs, IEEE documents, etc. for complete and authoritative
   protocol information.

   This is the the second revision of this document, and is intended to
   replace Section 5 of the first RMON-2 Protocol Identifiers document
   [RFC2074].

   The RMONMIB working group has decided to discontinue maintenance of
   this Protocol Identifier Macro repository document, due to a lack of
   contributions from the RMON vendor community. This document is
   published as an aid in implementation of the protocolDirTable.

2.1.  Terms

   Refer to the RMON Protocol Identifier Reference [RFC2895] for
   definitions of terms used to describe the Protocol Identifier Macro
   and aspects of protocolDirTable INDEX encoding.

2.2.  Relationship to the Remote Network Monitoring MIB

   This document is intended to describe some protocol identifier
   macros, which can be converted to valid protocolDirTable INDEX
   values, using the mapping rules defined in the RMON Protocol
   Identifier Reference [RFC2895].

   This document is not intended to limit the protocols that may be
   identified for counting in the RMON-2 MIB. Many protocol
   encapsulations, not explicitly identified in this document, may be
   present in an actual implementation of the protocolDirTable. Also,
   implementations of the protocolDirTable may not include all the
   protocols identified in the example section below.

2.3.  Relationship to the RMON Protocol Identifier Reference

   This document is intentionally separated from the normative reference
   document defining protocolDirTable INDEX encoding rules and the
   protocol identifier macro syntax [RFC2895].  This allows frequent
   updates to this document without any republication of MIB objects or
   protocolDirTable INDEX encoding rules.  Note that the base layer and
   IANA assigned protocol identifier macros are located in Reference
   document, since these encoding values are defined by the RMONMIB WG.

   Protocol Identifier macros submitted from the RMON working group and
   community at large (to the RMONMIB WG mailing list at '
   rmonmib@cisco.com') will be collected and added to this document.

   Macros submissions will be collected in the IANA's MIB files under
   the directory "ftp://ftp.isi.edu/mib/rmonmib/rmon2_pi_macros/" and in
   the RMONMIB working group mailing list message archive file
   "ftp://ftpeng.cisco.com/ftp/rmonmib/rmonmib".

2.4.  Relationship to Other MIBs

   The RMON Protocol Identifier Macros document is intended for use with
   the RMON Protocol Identifier Reference [RFC2895] and the RMON-2 MIB
   protocolDirTable [RFC2021]. It is not relevant to any other MIB, or
   intended for use with any other MIB.

3.  Protocol Identifier Macros

   This section contains protocol identifier macros for some well-known
   protocols, although some of them may no longer be in use.  These
   macros reference the base layer identifiers found in section 4 of the
   RMON Protocol Identifier Reference [RFC2895].  These identifiers are
   listed below:

         llc
         snap

         ianaAssigned
         802-1Q

   Refer to the RMON Protocol Identifier Reference [RFC2895] for the
   protocol identifier macro definitions for these protocols.

3.1.  Protocol Stacks And Single-Vendor Applications

   Network layer protocol identifier macros contain additional
   information about the network layer, and is found immediately
   following a base layer-identifier in a protocol identifier.

   The ProtocolDirParameters supported at the network layer are '
   countsFragments(0)', and 'tracksSessions(1).  An agent may choose to
   implement a subset of these parameters.

   The protocol-name should be used for the ProtocolDirDescr field.  The
   ProtocolDirType ATTRIBUTES used at the network layer are '
   hasChildren(0)' and 'addressRecognitionCapable(1)'. Agents may choose
   to implement a subset of these attributes for each protocol, and
   therefore limit which tables the indicated protocol can be present
   (e.g. protocol distribution, host, and matrix tables).

   The following protocol-identifier macro declarations are given for
   example purposes only. They are not intended to constitute an
   exhaustive list or an authoritative source for any of the protocol
   information given.  However, any protocol that can encapsulate other
   protocols must be documented here in order to encode the children
   identifiers into protocolDirID strings. Leaf protocols should be
   documented as well, but an implementation can identify a leaf
   protocol even if it isn't listed here (as long as the parent is
   documented).

    DESCRIPTION
       "SUN Remote Procedure Call Protocol. Port mapper function
       requests are sent to this destination port."
    CHILDREN
       "Specific RPC functions are represented as children of the sunrpc
       protocol.  Each 'RPC function protocol' is identified by its
       function number assignment. RPC function number assignments are
       defined by different naming authorities, depending on the
       function identifier value.
       From [RFC1831]:

       Program numbers are given out in groups of hexadecimal 20000000
       (decimal 536870912) according to the following chart:

                     0 - 1fffffff   defined by rpc@sun.com
              20000000 - 3fffffff   defined by user
              40000000 - 5fffffff   transient
              60000000 - 7fffffff   reserved
              80000000 - 9fffffff   reserved
              a0000000 - bfffffff   reserved
              c0000000 - dfffffff   reserved
              e0000000 - ffffffff   reserved

       Children of 'sunrpc' are encoded as [ 0.0.0.111], the protocol
       identifier component for 'sunrpc', followed by [ a.b.c.d ], where
       a.b.c.d is the 32 bit binary RPC program number encoded in
       network byte order.  For example, a protocolDirID-fragment value
       of:
           0.0.0.111.0.1.134.163

       defines the NFS function (and protocol).

       Children are named as 'sunrpc' followed by the RPC function
       number in base 10 format. For example, NFS would be named:
           'sunrpc 100003'."

       port- mapper program, and therefore decoded statically by
       monitoring RFC portmap requests [RFC1831]. Any subsequent packets
       must be decoded and correctly identified by 'remembering' the
       port assignments used in each RPC function call (as identified
       according to the procedures in the RPC Specification Version 2
       [RFC1831]).

       In some cases the port mapping for a particular protocol is well
       known and hard coded into the requesting client.  In these cases
       the client will not send portmap requests; instead it will send
       the SUNRPC request directly to the well known port.  These cases
       are rare and are being eliminated over time.  NFS is the most
       significant SUNRPC program of this class.  Such programs should
       still be declared as children of SUNRPC as described under
       CHILDREN above.  How an implementation detects this behaviour and
       handles it is beyond the scope of this document.

       The 'tracksSessions(1)' PARAMETER bit is used to indicate whether
       the probe can (and should) monitor portmapper activity to
       correctly track SUNRPC connections."

    DESCRIPTION
       "Novell Service Advertising Protocol.  This protocol binds
       applications on a particular host to an IPX/PEP or IPX/SPX socket
       number.  Although it never truly acts as a transport protocol
       itself it is used to establish sessions between clients and
       servers and barring well-known sockets is the only reliable way
       to determine the protocol running over a given socket on a given
       machine."
    CHILDREN
       "Children of SAP are identified by a 16 bit service type.  They
       are encoded as [ 0.0.a.b ], where 'a' is the MSB and 'b' is the
       LSB of the service type.

       Children of SAP are named as 'nov-sap a' where 'a' is the service
       type in hexadecimal notation.  The novell NCP protocol is
       referred to as 'nov-sap ncp' OR 'nov-sap 0x0004'."
    DECODING
       "The first packet of any session for a SAP based application
       (almost all IPX/PEP and IPX/SPX based applications utilize SAP)
       is sent to the SAP server(s) to map the service type into a port
       number for the host(s) on which the SAP server(s) is(are)
       running.  These initial packets are SAP packets and not
       application packets and must be decoded accordingly.

       Having established the mapping, clients will then send
       application packets to the newly discovered socket number.  These
       must be decoded by 'remembering' the socket assignments
       transmitted in the SAP packets.

       In some cases the port mapping for a particular protocol is well
       known and SAP will always return the same socket number for that
       application.

       Such programs should still be declared as children of nov-sap as
       described under CHILDREN above.  How an implementation detects a
       client which is bypassing the SAP server to contact a well-known
       application is beyond the scope of this document.

       The 'tracksSessions(1)' PARAMETER bit is used to indicate whether
       the probe can (and should) monitor nov-sap activity to correctly
       track SAP-based connections."

       "There is only one child of DRP, NSP.  This is encoded as [
       0.0.0.1 ]."
    ADDRESS-FORMAT
       "There are three address formats used in DRP packets, 2-byte
       (short data packet and all control except ethernet endnode &
       router hello messages), 6-byte (ethernet router & endnode hello
       messages) and 8-byte (long data packet).  All of these contain
       the 2-byte format address in the last 2 bytes with the remaining
       bytes being unimportant for the purposes of system
       identification.  It is beyond the scope of this document to
       define the algorithms used to identify packet types and hence
       address formats.

       The 2-byte address format is the concatenation of a 6-bit area
       and a 10-bit node number.  In all cases this is placed in little
       endian format (i.e. LSB, MSB).  The probe, however, will return
       them in network order (MSB, LSB).  Regardless of the address



Bierman, et al.              Informational                     [Page 62]

       format in the packet, the probe will always use the 2-byte
       format.

       For example area=13 (001101) and node=311 (0100110111) gives:
         0011 0101 0011 0111 = 0x3537 in network order (the order the
         probe should return the address in).

         In packets this same value would appear as (hex):

          2-byte  37 35
          6-byte  AA 00 04 00 37 35
          8-byte  00 00 AA 00 04 00 37 35

       Notice that the AA 00 04 00 prefix is defined in the
       specification but is unimportant and should not be parsed.

       Notice that control messages only have a source address in the
       header and so they can never be added into the conversation based
       tables."
    DECODING
       "NSP runs over DRP data packets; all other packet types are DRP
       control packets of one sort or another and do not carry any
       higher layer protocol.

       NSP packets are deemed to start at the beginning of the DRP data
       area.

       Data packets may be fragmented over multiple DRP data packets.

-- packets is beyond the scope of this document.]
--
-- Children of NetBIOS/NetBEUI are identified by the following (32 bit)

--
--      1   smb (Microsoft's Server Message Block Protocol)
--      2   notes (Lotus' Notes Protocol)
--      3   cc-mail (Lotus' CC Mail Protocol)
--
-- Children of NetBIOS/NetBEUI are encoded as [ a.b.c.d ] where 'a', 'b',
-- 'c' and 'd' are the four octets of the enumerated value in network
-- order (i.e.  'a' is the MSB and 'd' is the LSB).
--
-- For example notes over NetBEUI is declared as
--      'notes ::= { netbeui 2 }'
-- but is referred to as
--      'netbeui notes' OR 'netbeui 2'.
