Abstract
This memo defines textual conventions to represent the commonly used
Virtual Local Area Network Identifier (VLAN-ID). The intent is that
these textual conventions (TCs) will be imported and used in MIB
modules that would otherwise define their own representations.

Internet-Draft Textual Conventions for VLAN-ID september 2004
1. Introduction
Various Working Groups have defined standards-track MIB documents
(for example [RFC2613], [RFC2674] and [RFC3318]), that contain
objects and Textual Conventions to represent a Virtual Local Area
Network Identifier (VLAN-ID) [IEEE.802-1Q.2003]. New definitions are
showing up in various Internet-Drafts (for example
[I-D.ietf-ipcdn-qos-mib], [I-D.ietf-rmonmib-sspm-mib]).
Unfortunately the result is a set of different definitions for the
same piece of management information. This may lead to confusion and
unnecessary complexity.
This document defines a set of textual conventions (TCs) that can and
should be (re-)used in MIB modules, so that they all represent a
VLAN-ID in the same way. In fact, PIB modules can and should also
use these TCs when they need to represent a VLAN-ID.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].

4. Security Considerations
The MIB module contained in this memo does not define any management
objects. Instead, it defines a set of textual conventions which may
be used by other MIB modules to define management objects.
Meaningful security considerations can only be written for MIB
modules that define concrete management objects. This document has
therefore no impact on the security of the Internet.
5. IANA Considerations
IANA is requested to assign an OID under mib-2 to the MIB module in
section Section 3.
6. Acknowledgments
This document was produced as a result of a review of the use of
VLAN-ID in several MIB modules. Further investigation found that
VLAN-ID objects were defined in a few other MIB modules. The editor
would like to thank all who contributed to the discussion which
resulted in this document. Specifically Les Bell, Andrew Smith, Mike

Juergen Schoenwaelder, Richard Woundy, Tony Jeffree and William
Murwin. We also received input and feedback from IEEE confirming
that the values 0 and 4095 are not used for identifying a specific
VLAN-ID and so can be used to represent none or a wildcard (see
Appendix A).

Subject: RE: VLAn ID
Bert et al -
We have concluded that the use of 4095 as a wildcard is acceptable
to 802.1, and we will make any necessary changes to 802.1Q in due
course to relax the current stated restriction. However, we need
to know whether that is all that needs to be done to 802.1Q - i.e.,
is there any need to change our definitions of the managed objects
in the document (Clause 12) to reflect the interpretation of 4095
as a wildcard, or is this simply an issue for the SNMP machinery
to handle?
Regards,
Tony
