Specify the IEEE 802.3 frame format when optional envelope information is present while preserving the original MAC service data unit. Also, specify related adjustments to IEEE 802.3 Media Access Control (MAC) parameters and management attribute definitions. The purpose of this project is to extend the size of the IEEE 802.3 frame format to accommodate IEEE 802.1ad Provider Bridging, IEEE 802.1AE MACSec and other applications requiring envelope information. Amendment Standard - Superseded. This amendment to IEEE Std 802.3-2005 extends the IEEE 802.3 basic frame format with the addition of an envelope frame to accommodate additional prefixes and suffixes required by higher layer encapsulation protocols such as those defined by IEEE 802.1 (e.g., Provider Bridges, MAC Security), ITU-T or IETF (e.g., MPLS).
