IANA-CHARSET-MIB

Last Updated
2021-01-04
Registration Procedure(s)
See [Character Sets]
Description
This MIB module defines the IANACharset
TEXTUAL-CONVENTION. The IANACharset TC is used to
specify the encoding of string objects defined in
a MIB.

Each version of this MIB will be released based on
the IANA Charset Registry file, see [RFC2978] at
[https://www.iana.org/assignments/character-sets].

Note: The IANACharset TC, originally defined in
[RFC1759], was inaccurately named CodedCharSet.

Note: Best practice is to define new MIB string
objects with invariant UTF-8 [RFC3629] syntax
using the SnmpAdminString TC defined in [RFC3411]
in accordance with IETF Policy on Character Sets and
Languages [RFC2277].

Copyright (C) The Internet Society (2004). The
initial version of this MIB module was published
in [RFC3808]; for full legal notices see the RFC
itself. Supplementary information may be

IANA-IPPM-METRICS-REGISTRY-MIB

Last Updated
2015-08-14
Registration Procedure(s)
This module has been designated Obsolete. The registry will no longer be updated, and the current contents will be maintained as-is.
Description
With the approval and publication of [RFC6248], this module is
designated Obsolete.

The registry will no longer be updated, and the current contents will
be maintained as-is on the day that [RFC6248] was published.

The original Description text follows below:

This module defines a registry for IP Performance Metrics.

Registrations are done sequentially by IANA in the ianaIppmMetrics
subtree on the bases of 'Specification Required' as defined in
[RFC2434].

The reference of the specification must point to a stable document
including a title, a revision and a date.

The name always starts with the name of the organization and must
respect the SMIv2 rules for descriptors defined in
[RFC2578, Section 3.1];

A document that creates new metrics would have an IANA
considerations section in which it would describe new metrics to
register.

An OBJECT IDENTITY assigned to a metric is definitive and cannot
be reused. If a new version of a metric is produced then it is
assigned with a new name and a new identifier.

this MIB module was published in [RFC4148]; for full legal notices

Registration Procedure(s)

Expert(s)
Juergen Schoenwaelder, David Levi
Description
The MIB module registers object identifier values for
well-known programming and scripting languages. Every
language registration MUST describe the format used
when transferring scripts written in this language.

Any additions or changes to the contents of this MIB
module require Designated Expert Review as defined in
the Guidelines for Writing IANA Considerations Section
document. The Designated Expert will be selected by
the IESG Area Director of the OPS Area.

Note, this module does not have to register all possible
languages since languages are identified by object
identifier values. It is therefore possible to registered
languages in private OID trees. The references given below are not
normative with regard to the language version. Other
references might be better suited to describe some newer
versions of this language. The references are only
provided as `a pointer into the right direction'.
