Full Description

Scope

IEEE 802.1Q specifies a single PVID variable (Port VLAN Identifier) for each port of a switch. The configurable value of this single PVID variable specifies the VLAN into which frames untagged at ingress to the port are to be classified. The project will develop a supplement to 802.1Q to specify optional additional classification rules per port based on the protocol (as designated in the frame by 802 family portocols identifiers) in the received untagged frame. The project will consider compatibility and interoperability with existing 802.1Q bridges.

Purpose

Classifying multiple protocols into a single VLAN often imposes VLAN boundaries that are inappropriate for some of the protocols, requiring th presence of a non-standard entity to relay between VLANs the frames bearing the protocols for which the VLAN boundaries are inappropriate. The non-standard relay makes the boundaries of the VLANs transparent to the relayed protocols, depriving those protocols of the benefits of the VLANs. The proposed supplement will benefit users of multi-protocol LANs by permitting them to specify VLAN structures suitable for each protocol present in a LAN, and removing the need for a non-standard relay function between VLANs.

Abstract

Amendment Standard - Superseded. This amendment to IEEE Std 802.1Q,1998 Edition describes enhancements to allow for classification of incoming packets by methods other than source port. Specifically, it defines rules for classification based on data-link layer protocol identification. The document identifies proposed changes to the text of IEEE Std 802.1Q,1998 Edition that have arisen as a consequence of this activity. These are documented in the usual form for amendments to IEEE 802 standards; i.e., as an explicit set of editing instructions that, if correctly applied to the text of IEEE Std 802.1Q,1998 Edition, will create a corrected document.
