Did you create VLAN 10 on each device? Modern switch code will automatically create the VLAN when you assign an access port to it, but if I recall correctly setting a trunk native does not create the VLAN on its own.
Also, if you have interface F1/X and a .net file, you are talking about a 3725 or 3745 in Dynamips, not a 3750. Very different, and the IOS switches definitely need the VLAN to be created before its assigned. Bob -- Sent from my iPhone, please excuse any typos.
