Remote Network Monitoring MIB Protocol Identifier Macros

Status of this Memo

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].
    
    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:

ether2
llc
snap
vsnap
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'."
    DECODING
       "The first packet of many SUNRPC transactions is sent to the

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."

       itself it is used to establish sessions between clients and

       "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.

    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 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. The countsFragments(1) parameter indicates whether a probe can (and should) attribute non-leading fragments to the child protocol (above NSP in this case) or not.

       Recognition of DRP data packets and fragments is beyond the scope
