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. 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 Wijnen Expires March 25, 2004 [Page 1] Internet-Draft Textual Conventions for VLAN-ID September 2003 [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]. 3.

" SYNTAX Integer32 (0 | 1..4094) END 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. 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 Heard, Randy Presuhn, Dan Romascanu, Eduardo Cardona, Tom Petch, 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 Appendix A.

Email from Tony Jeffrey from IEEE -----Original Message----- From: Tony Jeffree [mailto:tony@jeffree.co.uk] Sent: Friday, 6th of June 2003 17:16 To: Wijnen, Bert (Bert) [mailto:bwijnen@lucent.com] 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?
