I would also love to see some documentation on how the bridge-mibs
are meant to be used.. Now, from memory, I think that ifStackTable
is used, so your interfaces appear in that table, and your ports
should also appear. The ifStackTable then says which port has which
interface as its parent. (That's a reaction to your last paragraph..)
