Extreme just began shipping its combined wireless and wired switches: I talked to the company for a story I did a while back and was impressed. I hate to say it, but I suspect that the presence of already established switch makers like Extreme in the WLAN switch market is bad news for the WLAN switch startups.
Extreme's CEO, Gordon Stitt, is pretty critical of Cisco's approach to WLANs. Even though he's talking about his competitor, he's right when he says that Cisco is in a tough spot because it is trying to offer management features to an installed base of customers that already have Cisco APs, which were designed to operate independently. Cisco is now trying to add on central management functions, but I'm not sure that's possible as an afterthought.
