    What are you plugging into the switches and what does the log say.

    Are you looking for auto crossover detection (auto MDI/MDIX)?

    If so, I honestly didn't notice it until the Cat 2960s were released. I don't think that it was supported on the 2950s (but could be wrong).

    I just read something to suggest this is the case, only later switches support auto mid-x. Support for auto mdi in routers is worse so using the correct cables is a must.

    My understanding is that the term "autosensing" is referring to 10/100 and not the auto mid-x, and from switch to switch would be cross over (like to like) need a cross over, and unlike to unlike a straight through would work is what I have learned in the Cisco world... My main home switches use auto mid-x.

    What tazdevil said.

    Autosensing = It will automatically select the required port speed and duplex.
    Auto-MDIX = It will automatically do the crossover for you if necessary.

    Easy to assume that it's supported - After all, $20 Netgear switches have had an auto uplink port for years :)
