Wow - what a great switch, without the hassle of anything associated with Cisco. This switch does link aggregation, and I had bought it to connect to a Synology Disk Station 412 - the combination works perfectly giving me huge transfer rates for streaming content to multiple devices - for the price it has amazing functionality.
The hardware is fan-less, providing silent running; although it is powered by an external power adapter - the adapter is well made, and comes with a detachable 'kettle lead' allowing you to plug it into a UPS without having to do creative wiring. The case is well made and finished off, and feels like a quality piece of kit.
The switch has two SFP ports on it - which I have also connected up to a second switch (of the same type) for handling IP Cameras - the PoE works perfectly too; auto detecting and supplying power where needed. Creating a VLAN trunk over a LAG to the second switch using NetGear SFP cables was very easy indeed (it took me approx 20 minutes to plan and deploy) - the LAG provides 2 Gb connectivity between the two switches providing more than enough bandwidth. I can also confirm that the spanning tree protocol on these devices works well - unlike many other higher priced switches.
The switch does not have any real layer 3 capability - but the layer 2 capability it has is robust, and quite easy to configure via a web based GUI.
The only real cons I have regarding the switch is the lack of security related to a basic configuration out of the box. It would have been nice if NetGear had provided the device with default SSL configuration - and local users. Out of the box the configuration is a simple password and no SSL for the management interface, which is adequate for most small deployments. Another small frustration is that the GUI is a little unpolished (the help text is a little lacking) - however, this is to be expected for a device at this price point.
The switch is also connected to a SonicWall TZ105 - again this works perfectly, segregating my wi-fi traffic into VLANs for better QoS management relating to guests and local users.
During the first week of use I transferred over a 2 terabytes of data through the switch, during which the device dropped 22 packets with errors (which I think was because I was unplugging stuff).
I am very happy with this component, and I can't recommend Netgear equipment high enough - on the whole I find it much easier to configure and setup than Cisco, and often it has fewer firmware bugs. Netgear, unlike Cisco also provide you with access to all the documentation for the components that you own... you don't need to be a member of a special club or a re-seller.... i.e. they treat you like a proper customer!
