mac-address

There is two are interconnected Cisco WS-2950T.

By the one GBIC port on first switch connected a first NIC of bonding interface, and by the one GBIC port on second switch connected a second NIC of bonding interface.

Of course the both switches sees the bonding MAC-address only on one interface (eg it is GBIC on first switch) and all incoming traffic for bonding interface passes through this GBIC.

But in "mode=5" all outgoing traffic are distributed between the all interfaces that make bond. In this case, the packets will be dropped from the second switch and anyway will going through the first switch? Or the division will be working?
