quality of allied telesyn switch
most of switches used in my organization are allied telesyn. recently i have a strange experience with our servers at dmz. upload files via ftp is very slow and never completed at all, but the download is fine and normal. i’ve tried sftp too but also had the same problem. slow upload but normal download.
i suspected the problem was on our mikrotik router which using HP desktop. i thought may be it was the LAN card. i even built a new mikrotik router using IBM thinkcenter to replace the HP. but did not have the chance to replace it because i had another thought that it could be the switch allied telesyn AT-FSW716 who caused the problem.
so i took a cross cable, plug it to connect the mikrotik and a server directly, then do ftp again from a computer on LAN zone. the result was very good, upload is very fast as it was the download. so my guess was right that it could be the switch who caused the problem.
so then i took a new switch from our supply, it’s AT-FS750/16 and installed it on the rackmount under the troubled AT-FSW716… move all cables to the new switch and rip off the troubled switch from the rack…. 
test upload and download again, the result was very well… what’s the lesson in this? do not use AT-FSW716 ever again…….
