Speed/Duplex Auto-Negotiation Problems
02/25/2014
This review is from: Cisco Small Business 100 Series SG100D-08P-NA Smart 8-Port PoE Desktop Gigabit Switch
Pros:
Small size.
Reasonable PoE power budget for the 4 ports which are PoE enabled.
Cons:
Large external power brick but that's the trade-off for having the switch itself remain small.
The much larger issue is the speed auto-negotiation problems. It is consistently not able to negotiate gigabit speed with anything plugged into it. Nearly all devices I connect will negotiate 10mbps, half-duplex. That sort of behavior is difficult or impossible to fix if the other device is another switch. Even when hard-setting the connected device to 1Gbps, there is no guarantee that it will actually work.
Overall Review:
I've had consistently better results with the ZyXEL PoE switches and usually at a better price. I went with this Cisco switch because physical size is an issue in this particular installation.
