    What if there is a hub, other switch, or host with multiple MAC addresses connected to the switch interface? That is common enough. Join the IEEE to propose your solutions, but such speculation is off-topic her. This is not a discussion forum, and questions seeking primarily opinion-based answers are off-topic.

  • @RonMaupin, yes I neglected the case where multiple MACs can be on a single port so you are correct. You gave me a technical answer to my question. I don't believe my question was off topic, if anything, the I phrased the title so it might have appeared that way by referring to "standards". However, it was more about the technical feasibility.

  • (sigh) NO. This is yet another hair-brained scheme from someone who does not understand what they're trying to change. SRC/DST MAC's exist at layer-2 for a reason. (there is an infinity of edge cases you're ignoring or are simply unaware of.) Read all of the questions w.r.t. doing away with IP "because we have MACs". (also, those 6 bytes are about 0.4% of an ethernet frame.) Commented Nov 16, 2024 at 16:14
  • @Ricky, Hair-brained scheme or a question from someone new to the topic? :) Commented Nov 16, 2024 at 16:25
