This question is mainly about the logic of unmanaged switches.
I've seen posts here and elsewhere saying that it's okay to plug in a switch to a SOHO router (using a crossover if necessary), which is basically the same as plugging a switch into a switch. I need to do this for a business to extend the amount of ethernet ports on their router.
I don't understand how this is possible. Won't the router see many computers connected to one port, thus resetting what mac address it thinks is at that port every time a new message is sent? I would think that would have performance consequences, unless I'm wrong here.
