same problem here. we used to have 155 enterasys switches that was working perfectly. after extreme buy enterasys we started to change our switches to 450 and 460G2 and that was when our life became a hell! All kind of problems!! Power suply that burns, poor and confusing online documentation, no support for netsight management. We are now going to change our switches to huawei and so far very pleased with our choice. came here because we still have like 20 switches that we need to authenticate by radius and we are going to the 3rd day and so far no success!! All our 100 huawei switches are already authenticating by radius, all done in one day!! A simple image download is EXTREME difficult to get done. You need an account, then you gave to login at theys website, the you find a bunch of versions not organized!
I GUESS THAT IS WHY THEY NAMED THEIR COMPANY "extreme"!! Everything EXTREME difficult!!
Good slogan for you guys!!
