We have about 20+ BS-G2116U swithes in my lan (300 computer Lan). We have experienced the slower and slower network performance after installing more this switches. I use microsoft network monitor to watch the network traffic and found the MAC address started from 10-6F-3F-xx-xx-xx were brocast to whole lan like crazy. It broadcast "UndescribedFrameData:Length = 46 ,[*BROADCAST [FF-FF-FF-FF-FF-FF]]" to net work 2,500 times in 2 minutes. 10-6F-3F-xx-xx-xx is belong to BUFFALO INC and double check the MAC on the switch and confirmmed the BUFFALO switch caused these problems. Can anyone help? :)
