Abstract
This document defines the procedures for IANA to administer and
maintain the Object Identifier (OID) tree under the Remote Monitoring
(rmon) root. This memo also documents the currently assigned values.
1. Introduction
The RMONMIB Working Group so far has maintained its own registry for
OID assignments for new MIB modules under the root OID for rmon
[RFC2819]. This has worked reasonably well, although errors had to
be corrected at a late stage one or two times, and a few now defunct
assignments have been made as well.
It is also a somewhat non-standard way of doing things, because
normally a new standards track MIB module will get a MIB root
assigned at the time that the module is being published as part of an
RFC.
This document lists the currently assigned rmon OIDs. It also
describes the procedures and rules for new assignments and asks IANA
to take over the responsibility for existing and future assignments.
The current assignments are not all too logical. Initially normal
MIB OIDs were assigned under rmon, but at a later time the WG used
the rmon root OID to create new MIB modules underneath it. Some
people will claim 'an OID is just an OID', and while this is true, it
does not make things easier if the organisation of OIDs is not
logical. However, we cannot change what has been assigned in the
past. From now on, only MODULE-IDENTITY macro (MIB root) assignments
will be made (by IANA) under the 'rmon' node. Within a MIB module,
the working group authors/editors can then assign their own OIDs
according to normal procedures.
2. Currently assigned OIDs under the rmon root
At the time of this writing, the following OIDs have been assigned
and IANA has picked up this information in their public registry of
assigned values. They are listed as part of the already existing
smi-numbers registry at:
http://www.iana.org/assignments/smi-numbers
...mib-2.rmon (1.3.6.1.2.1.16)
The assignments under ...mib-2.rmon were maintained by the RMONMIB
Working Group until publication of RFC 3737. Some (early)
assignments may not look all too logical. That is true, but that is
history and cannot be changed. From now on, only MODULE-IDENTITY
macro (MIB root) assignments will be made (by IANA) under the 'rmon'
node.

3. How to request a new assignment for a MIB module
When anyone is writing a internet-draft for which a new assignment is
needed/wanted under the rmon OID, then the proper way to do so is as
follows:
EXAMPLE-MIB DEFINITIONS ::= BEGIN
IMPORTS
rmon FROM RMON-MIB
.. other imports ..
exampleMIB MODULE-IDENTITY
... other normal MODULE-IDENTITY stuff ...
::= { rmon nnn } -- IANA: please assign nnn
-- RFC-Editor: replace nnn with IANA-assigned
-- number and remove this note
IANA will assign the number as part of the RFC publication process.
4. Security Considerations
This memo describes procedures for IANA assignment of OBJECT
IDENTIFIER values, and has no impact on the security of the Internet.
5. IANA Considerations
IANA has picked up the initial set of assignments and integrated them
into the existing registry for smi-numbers at:
http://www.iana.org/assignments/smi-numbers
The list is presented in Section 2.
IANA is requested to maintain this registry for future assignments.
New assignments can only be made via Standards Action as described in
[RFC2434].
IANA will assign the number as part of the RFC publication process.
6. Acknowledgments
This document was produced as a result of discussion between the
Operations and Management AD responsible for Network Management and
the WG chair for the RMONMIB Working Group. Thanks to Andy Bierman
for keeping and administering the registry up to this point in time.
The document has been reviewed by the RMONMIB Working Group.

§1Why the Registry Moves to IANA
The RMONMIB Working Group had so far kept its own registry of Object Identifier (OID) assignments under the rmon root of RFC 2819. It worked reasonably well, but errors had to be corrected at a late stage once or twice, and a few now defunct assignments had been made.
It was also unusual. Normally a new standards track MIB module gets its MIB root when it is published as an RFC. So this document lists the current assignments, sets out the rules for new ones, and asks IANA to take over responsibility for existing and future assignments.
The authors admit the current assignments are not very logical: normal MIB OIDs were first assigned under rmon, and later the working group used the rmon root to create new MIB modules beneath it. That history cannot be changed. From now on, only MODULE-IDENTITY macro (MIB root) assignments will be made by IANA under the rmon node.
One group kept its own list of numbers, which was a bit messy. Now the official number-keeper takes over the list.
§2Numbers Already Assigned
The assignments under mib-2.rmon (1.3.6.1.2.1.16) were maintained by the RMONMIB Working Group until this RFC was published. IANA has picked them up in its existing smi-numbers registry.
The first table lists numbers { rmon nnn } from 0 to 32. Entries 0 to 9 come from RFC 2819 (statistics, history, alarm, hosts, hostTopN, matrix, filter, capture, event, plus the notifications root at 0). Entry 10 is tokenRing from RFC 1513, and entries 11 to 20 come from RFC 2021. Later entries are module roots such as switchRMON (22, RFC 2613), apm (23, RFC 3729), dsmonMIB (26, RFC 3287), interfaceTopNMIB (27, RFC 3144) and hcAlarmMIB (29, RFC 3434).
Some entries are special. Number 24 is available, number 25 (pmCapsMIB) is defunct, and numbers 28, 30, 31 and 32 are reserved for sspmMIB, tpmMIB, raqmon and raqmonDs, which were still Internet-Drafts.
A second table covers the rmonConformance node (1.3.6.1.2.1.16.20), with ten entries for compliance and group definitions and for hcRMON (5) and rmonMibModule (8).
The RFC prints the full list of drawer numbers already used, and marks which ones are free, reserved or no longer in use.
§3How to Request a New Assignment
An author of an Internet-Draft who needs a number under the rmon OID writes the MIB module with a placeholder. The module imports rmon from RMON-MIB, defines a MODULE-IDENTITY, and ends with ::= { rmon nnn } followed by a note asking IANA to assign nnn and asking the RFC Editor to replace it and remove the note.
IANA assigns the number as part of the RFC publication process. Within the new module, the authors and editors then assign their own OIDs by the normal procedures.
When you write a new monitoring document, you leave a blank where the number goes. The number-keeper fills it in when the document is published.
EXAMPLE-MIB DEFINITIONS ::= BEGIN
IMPORTS
rmon FROM RMON-MIB
.. other imports ..
exampleMIB MODULE-IDENTITY
... other normal MODULE-IDENTITY stuff ...
::= { rmon nnn } -- IANA: please assign nnn
-- RFC-Editor: replace nnn with IANA-assigned
-- number and remove this note§4IANA Considerations
IANA has integrated the initial set of assignments into the existing smi-numbers registry and is requested to maintain the registry for future assignments. New assignments can only be made via Standards Action, as described in RFC 2434, the guidelines for writing an IANA Considerations section.
New numbers are only given out for documents that have gone through the full standards process.
§5Security Considerations
The RFC describes procedures for IANA assignment of OBJECT IDENTIFIER values and states that it has no impact on the security of the Internet. It adds no protocol and changes no behavior of any monitored device.
It is just a numbering rule, so it does not change how safe anything is.
