I have an odd question. I know if I have a half duplex configured port on one side of an Ethernet interface and full duplex on the other that I get a duplex mismatch and while it "works" performance is degraded from the runt frames. If I replace the non-half duplex side with a switch with a SFP fiber module that connected to a fiber to Ethernet media converter to change the physical media would the situation be exactly the same? i.e. it would "work" but I would get runts accumulating in the counters. My understand is on a 10Gbe interface that since the concept of half-duplex never existed that the port would always be full duplex so negotiating to half duplex wouldn't be an option.
