Summary: I bought this switch to replace an aging 5-port gigabit switch. I needed the additional ports, wanted the ability to do separate VLANs, and admired the Cisco name. Unfortunately, the SG200 series has been crippled in comparison to its SG300 series cousins. This switch will often behave like a L3 firewall. It drops IP fragments and it doesn't support jumbos. None of these "features" are readily described in the documentation.
Summary: On my third order I ultimately received a switch where all the ports worked.. I suspect this degree of QC may not be limited to Cisco: I ultimately ordered 4 of the D-Link 5 port Gigabit switches for the 2 that I needed.. Same problem: one or more of the channels was quiet..
Summary: Overall, this is a nice switch for a fair price, but BEWARE the latest firmware, 1.06.2 at the time I publish this review. I took 1 networking class in college, but I do remember that switches should operate at Layer 2 of the OSI model, meaning the datalink level. Ok, that sounds like technical babble to most of you, but let me tell you why you should care.
