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].

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.

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'.
