    Default Connect a 4404 to a 3350 switch

    All,

    Never worked with wireless other thank my Netgear before and I find myself helping a friend today on her CCNA wireless.

    I am setting up a Cisco 4402 WLC to connect to a Cisco 3550 switch here in a lab. When I directly connect my laptop I get physically connectivity fine. But when I attempt to plug into a switch I get nothing. No lights or anything. I tried another switch jut to be sure. Same thing.

    I am GUESSING there is some sort of trunking going on that I need to configure or some CDP setting I need to tweak. Any reason you guys can think that I would not be getting layer 1 connectivity here? tried a cross over cable as well, thought it might be a MDI thing. Nope.

    hmm, often even from the laptop I am getting random lost packets. Starting to think this is a bad GLC-T.

    I know you have to setup a dot1q trunk from the switch to WLC but I don't think that would cause layer 1 issues. Not sure if you'll need a crossover cable since from the 3560s onward it has autosensing which converts a straight cable to crossover so we never have to think about looking for a crossover cable when cabling stuff anymore. Can you console into the wlc? Is it set to default? If not there may be some obscure previous config screwing up the connection.

    I haven't deployed a WLC in a couple of years so I don't remember the exact details. You can try googling it there were plenty of walk throughs.
    In life you have to make your own opportunities. Don't let anyone stop you from your dreams to many negative people want you to fail because they can't succeed.

    From what I can remember, GLC-Ts don't negotiate speed; they only work when connected to gigabit ports. Are you using a GBIC on your 3550?
