GigE is PtP at the physical-layer by the IEEE 802.3ad specification. It's just not possible to have a dumb, GigE hub. You have to have a switch that can be told to L2-forward everything to one or more ports (e.g. through a port-mirroring feature, or by disabling MAC learning). Also, though probably not terribly relevant, various switches have various bugs/malfeatures that cause them to consume certain kinds of frames rather than forward them (e.g. consuming all or certain kinds of ISO frames). regards, -- Paul Jakma [email protected] [email protected] Key ID: 64A2FF6A Fortune: lisp, v.: To call a spade a thpade.
