Remote Network Monitoring MIB Protocol Identifier Macros
Remote Network Monitoring MIB Protocol Identifier Macros 🎀
Okay bestie, this is RFC 2896 💖 Its title block lists the authors as A. Bierman, C. Bucci (Cisco Systems, Inc.) and R. Iddon (3Com, Inc.). It's Informational, dated August 2000, and the title block doesn't list anything it obsoletes or updates ✨

Abstract 🌸
Okay so this memo has a bunch of protocol identifier examples, and you can use them to build valid protocolDirTable INDEX encodings. That's defined in the Remote Network Monitoring MIB (Management Information Base) Version 2 [RFC2021] and the RMON Protocol Identifier Reference [RFC2895] 🧚
This doc has protocol identifier macros for well-known protocols. You can run a conformant RMON-2 MIB [RFC2021] implementation without using these identifiers at all, so this document doesn't specify any IETF standard. It's published to encourage better interoperability between RMON-2 agent implementations, because it packs a ton of RMON-related protocol info into one place 💅
The first version of the RMON Protocol Identifiers Document [RFC2074] got split up. The standards-track Reference portion is now [RFC2895], and this document is the "RMON Protocol Identifier Macros" one, which holds the non-normative part of that spec 🍓

The SNMP Management Framework is currently made of five major components 🧩
- An overall architecture, described in RFC 2571 [RFC2571].
- Mechanisms for describing and naming objects and events for management purposes. The first version of this Structure of Management Information (SMI) is called SMIv1, and it's described in STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215 [RFC1215]. The second version, SMIv2, is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
- Message protocols for transferring management information. The first version of the SNMP message protocol is SNMPv1, described in STD 15, RFC 1157 [RFC1157]. A second version, SNMPv2c, isn't an Internet standards track protocol, and it's described in RFC 1901 [RFC1901] and RFC 1906 [RFC1906]. The third version of the message protocol is SNMPv3, described in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
- Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is in STD 15, RFC 1157 [RFC1157]. A second set of protocol operations and associated PDU formats is in RFC 1905 [RFC1905].
- A set of fundamental applications described in RFC 2573 [RFC2573], plus the view-based access control mechanism described in RFC 2575 [RFC2575].
If you want a deeper intro to the current SNMP Management Framework, check out RFC 2570 [RFC2570] 🦋
Managed objects get accessed through a virtual information store called the Management Information Base, or MIB. Objects in the MIB are defined using the mechanisms in the SMI.
This memo doesn't 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 has examples of protocol identifier encapsulations, which you can use to describe valid protocolDirTable entries. The syntax of the protocol identifier descriptor is defined in the RMON Protocol Identifier Reference [RFC2895].
This doc isn't meant to be the authoritative reference on the protocols it covers. For complete and authoritative protocol info, go to the Official Internet Standards document [RFC2600], the Assigned Numbers document [RFC1700], or other appropriate RFCs, IEEE documents, and so on ✨
This is the second revision of this document, and it's meant to replace Section 5 of the first RMON-2 Protocol Identifiers document [RFC2074] 💜
The RMONMIB working group has decided to stop maintaining this Protocol Identifier Macro repository document, since the RMON vendor community didn't contribute much. It's published to help with implementing the protocolDirTable 🫶
2.1. Terms
Check the RMON Protocol Identifier Reference [RFC2895] for definitions of the terms used to describe the Protocol Identifier Macro and the aspects of protocolDirTable INDEX encoding 📖
2.2. Relationship to the Remote Network Monitoring MIB
This document describes some protocol identifier macros. You can convert them into valid protocolDirTable INDEX values using the mapping rules in the RMON Protocol Identifier Reference [RFC2895] 🎀
This document doesn't limit the protocols that can be identified for counting in the RMON-2 MIB. Lots of protocol encapsulations that aren't explicitly listed here might show up in a real protocolDirTable implementation. Also, a protocolDirTable implementation doesn't have to include all the protocols in the example section below 🍓
2.3. Relationship to the RMON Protocol Identifier Reference
This document is intentionally kept separate from the normative reference doc that defines protocolDirTable INDEX encoding rules and the protocol identifier macro syntax [RFC2895]. That means this doc can get frequent updates without republishing any MIB objects or INDEX encoding rules. The base layer and IANA assigned protocol identifier macros live in the Reference document, since the RMONMIB WG defines those encoding values 💅
Protocol Identifier macros submitted by the RMON working group and the wider community (to the RMONMIB WG mailing list at rmonmib@cisco.com) will be collected and added to this document 🫶
Macro submissions get 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 meant to be used with the RMON Protocol Identifier Reference [RFC2895] and the RMON-2 MIB protocolDirTable [RFC2021]. It isn't relevant to any other MIB, and it isn't intended for use with any other MIB 🙅♀️
3. Protocol Identifier Macros 🦋
This section has protocol identifier macros for some well-known protocols, though 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]. The base layer identifiers are listed below:
ether2
llc
snap
vsnap
ianaAssigned
802-1QCheck the RMON Protocol Identifier Reference [RFC2895] for the protocol identifier macro definitions of these protocols 📖
3.1. Protocol Stacks And Single-Vendor Applications 🧚
Network layer protocol identifier macros hold extra info about the network layer. They sit right after a base layer identifier in a protocol identifier 🌸
The ProtocolDirParameters supported at the network layer are countsFragments(0) and tracksSessions(1). An agent can 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 can choose to implement a subset of these attributes for each protocol, which limits which tables the indicated protocol can appear in (for example, protocol distribution, host, and matrix tables) 💜
The protocol-identifier macro declarations below are only examples. They aren't meant to be an exhaustive list or an authoritative source for any of the protocol info given. That said, any protocol that can encapsulate other protocols must be documented here, so its children identifiers can be encoded into protocolDirID strings. Leaf protocols should be documented too, but an implementation can identify a leaf protocol even if it isn't listed here, as long as its parent is documented 🍓
3.1.1. The TCP/IP protocol stack 🌈

DESCRIPTION
"The protocol identifiers for the Internet Protocol (IP). Note
that IP may be encapsulated within itself, so more than one of
the following identifiers may be present in a particular
protocolDirID string."
CHILDREN
"Children of 'ip' are selected by the value in the Protocol field
(one octet), as defined in the PROTOCOL NUMBERS table within the
Assigned Numbers Document.
The value of the Protocol field is encoded in an octet string as
[ 0.0.0.a ], where 'a' is the protocol field .
Children of 'ip' are encoded as [ 0.0.0.a ], and named as 'ip a'
where 'a' is the protocol field value. For example, a
protocolDirID-fragment value of:
0.0.0.1.0.0.8.0.0.0.0.1
defines an encapsulation of ICMP (ether2.ip.icmp)"
ADDRESS-FORMAT
"4 octets of the IP address, in network byte order. Each ip
packet contains two addresses, the source address and the
destination address."
DECODING
"Note: ether2.ip.ipip4.udp is a different protocolDirID than
ether2.ip.udp, as identified in the protocolDirTable. As such,
two different local protocol index values will be assigned by the
agent. E.g. (full INDEX values shown):
ether2.ip.ipip4.udp =
16.0.0.0.1.0.0.8.0.0.0.0.4.0.0.0.17.4.0.0.0.0

sunrpc PROTOCOL-IDENTIFIER
PARAMETERS {
tracksSessions(1) -- learn port mapping of programs
}
ATTRIBUTES {
hasChildren(0) -- port mapper function numbers
}
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."

Okay the Novell stack is giving main character energy 💅 Here's the base IPX protocol first:
ipx PROTOCOL-IDENTIFIER
PARAMETERS { }

DESCRIPTION
"Novell IPX"
CHILDREN
"Children of IPX are defined by the 8 bit packet type field. The
value is encoded into an octet string as [ 0.0.0.a ], where 'a'
is the single octet of the packet type field.
Notice that in many implementations of IPX usage of the packet
type field is inconsistent with the specification and
implementations are encouraged to use other techniques to map
inconsistent values to the correct value (which in these cases is
typically the Packet Exchange Protocol). It is beyond the scope
of this document to describe these techniques in more detail.
Children of IPX are encoded as [ 0.0.0.a ], and named as 'ipx a'
where a is the packet type value. The novell echo protocol is
referred to as 'ipx nov-echo' OR 'ipx 2'."
ADDRESS-FORMAT
"4 bytes of Network number followed by the 6 bytes Host address
each in network byte order."
REFERENCE
"The IPX protocol is defined by the Novell Corporation
A complete description of IPX may be secured at the following

802-1Q 0x05000001 -- 1Q-IANA [5.0.0.1]
-- (ipxOverRaw8023)
}So IPX is the base layer, and its children hang off the 8-bit packet type field, written as [ 0.0.0.a ]. The doc is honest that a lot of real IPX stacks use that field inconsistently 😭 so implementations are encouraged to map the weird values to the right one (usually PEP), and the doc says the details of how are out of scope. Its address format is 4 bytes of network number plus 6 bytes of host address, both in network byte order.

Its children are keyed by 16-bit socket values, and the doc says how source and destination sockets get mapped to that one socket value is out of scope.

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."

::= { nov-pep 0x0452 }SAP is the Service Advertising Protocol and it's the matchmaker 💘 Clients ask the SAP server which socket a service lives on, then send their real app packets to that socket. The doc says those first SAP packets are not app packets, so they have to be decoded as SAP. Sometimes the port is well known and SAP just always returns the same number, but those programs still count as children of nov-sap. And tracksSessions(1) tells you whether the probe can (and should) keep an eye on nov-sap activity to track those connections. The service type list lives at the ftp link in the reference, which I've kept exactly as written.

REFERENCE
"BANYAN"
::= { vipc 0x00 }Banyan Vines is where things get extra spicy 🌶️ vip is the main IP-ish layer, and its children are picked out by the one-byte protocol type at offset 5, with a vipc example in the doc. vipc is the IPC thing, and the doc has a little note saying Banyan treats vipc, vipc-dgp and vipc-rdp as one protocol even though IPC really comes in two flavours 🦋 Unreliable datagrams are packet type 0x00 and reliable ones are 0x01, so they need two "virtual" protocols to tell them apart. vipc-dgp is the unreliable datagram bit, and it's got a short 6-byte header with a single padding byte. Main character energy for sure 💅✨

::= { vipc 0x01 }So the big vibe here: children of vipc-rdp are found by the 16-bit port numbers sitting in the vipc header 💅 Their children get written as [ 0.0.a.b ], and StreetTalk rides on top as vipc-rdp streettalk or vipc-rdp 0x000F ✨ Which port gets used to pick the child is up to each implementation, and the spec doesn't go there 🙈
The decoding part is where it gets spicy 🌶️ The child protocol starts after the error/length field at the end of the vipc header, and that header is a "long" one, 16 bytes total with that final field included 🫶 vipc-rdp also has a fragmentation scheme that lets up to four vipc packets go out as one atomic PDU.

DESCRIPTION
"DEC Routing Protocol."
CHILDREN
"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
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
of this document."

}The address bit is the one I'm most obsessed with 😭 DRP has three address formats, 2-byte, 6-byte, and 8-byte, and they all end with the same 2-byte address. The 2-byte one is a 6-bit area plus a 10-bit node number, stored little endian in packets but returned in network order by the probe 🫶 The spec's example is area 13 and node 311, which comes out as 0x3537 in network order, and the byte layouts are shown in the block above. The AA 00 04 00 prefix is in the spec but it's not important and shouldn't be parsed 🙈 Also, control messages only carry a source address, so they can never be added to the conversation-based tables. Not me being dramatic about it, it's just the rule 💀
Decoding-wise, NSP runs over DRP data packets, and every other DRP packet type is a control packet that doesn't carry a higher layer protocol 🦋 NSP packets start at the beginning of the DRP data area, and data can be fragmented across multiple DRP data packets. The countsFragments(1) bit says whether a probe can and should attribute the non-leading fragments to NSP-and-above or not ✨ And figuring out what counts as DRP data packets and fragments is out of scope here 💅

Okay, NetBIOS is where the spec really sets the scene 🌈 The comment block below explains that NetBIOS and NetBEUI run over a bunch of different transports, but they all share two things: sessions get set up by connecting to locally named services, and sessions carry the application data between the client and that named service 💖 Which application protocol is inside those data packets is out of scope, so the children are just a 32-bit enumeration: smb, notes, and cc-mail 💜
-- CHILDREN OF NETBIOS
-- The NetBIOS/NetBEUI functions are implemented over a wide variety of
