In an effort of figuring out a metro ethernet access network to carry =
Internet access services,=20

I'm comparing the approaches of several equipment manufacturers insofar =
as how,

they allow a metro service provider to provide point-to-multipoint =
E-TREE public services,

(where the leaves of the multipoint tree are different billing entities =
from that of the root of the tree),

such that it remains possible to distinguish at the root traffic =
originating from a given service provider demarcation device in the =
tree.

In an effort to solve this problem, I am finding myself diving deep down =
into the behaviour of Ethernet switches at the 802.1Q 2005 bridge =
behaviour.

I would appreciate feedback from people whom are aware since WHEN and =
under which conditions, Ethernet switches have begun to implement =
separate MAC addresses for every client ports.

and whether such MAC addresses draw from the global pool of MAC =
addresses.

A cursory understanding of this leads me to believe that as soon as a =
switch is capable of spanning tree on a downstream client port, it must =
have separate MAC addresses for every client port.

Feedback appreciated
