Of course, any multi-hop L2 path goes through MAC relays. But in your diagram, there is no L2 path from the *TX interface* of OAM sublayer A to *RX interface* of OAM sublayer Z, with or without MAC relays. It has nothing to do with VLC sublayer and where it is located.

OAM A and OAM Z are OAM Sublayer entities.

OAM A might be a “Manager” for OAM Z (e.g. OAM Z is on an ONU)

Agreed, an L2 path needs to exist… it could exist via the MAC relay, but VLC is below MAC relay, so how does the frame get back up the stack?

What are OAM A and OAM Z exactly, in IEEE terms? Are these OAM Clients?

For OAM Client A to talk to OAM Client Z, there should exist a L2 path from TX interface of OAM sublayer A to RX interface of OAM sublayer Z. You diagram does not show any such path.

I should have asked my question more specifically...

What happens if OAM A wants to talk to OAM Z via VLC?

The OAMPDUs received by the port on the left (MAC A) will be delivered to OAM client located above OAM SL Z (not shown). This is one direction of the use case described in 8A.3.

The diagram below corresponds to the direction from Station S to Manager M. Port A below is the same as Bridge Y Port 0 here, port Z is the same Port M (Manager) here. The diagram below shows only one intermediate bridge, but there can be any number of them.

Glen, et al,

Given the topology and rule in the picture below, what is the expected behavior?
