The fiber (uplink) ports (on, say, 1900XLs and 2900XLs) are a perfect example of what we're talking about. To the switch, it's just another 100Base-FX port, with no concern as to whether it's "uplinked" to another switch or router, or even to a server with a 100Base-FX NIC. > Usually an uplink port is not crossed, I thought. > > A hub or switch must do a cross-over internally at each normal > (network) port to make sure TX gets to RX and RX gets to TX. > > An uplink port is not crossed, however. I believe you are correct here. I said something that didn't represent what I was thinking. My thought was that normally you connected an end-device to a hub with a straight-through cable, whereas to connect a "regular" hub port to another "regular" hub port would need a crossover, and a connection to a "uplink" hub port wouldn't. Oh well.... it's all the same..... Thanks! Mike W.
