Standard and Enhanced Images
The DGS-3120 Series is embedded with two different software images - Standard Image (SI) and Enhanced Image (EI). The Standard Image provides sophisticated features for campus, or enterprise. It includes advanced Quality of Service (QoS), traffic shaping, L2 multicasting, and robust security features. The Enhanced Image supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, sFlow, IPv6 features which are suitable for the next generation IPv6 networks or triple play applications in Metro Ethernet.



Enhanced Network Reliability
The DGS-3120 Series targets enterprise/campus and customers who require a high level of network security and maximum uptime. All the models in DGS-3120 series support an external redundant power supply so that continued operation can be assured. They also include other features, such as 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and Broadcast Storm Control, that enhance network resilience. The G.8032 Ethernet Ring Protection Switching (ERPS) function minimizes the recovery time to 50 ms. For load sharing and redundancy backup in switch cascading/server attachment configuration, the DGS-3120 Series provides dynamic 802.3ad Link Aggregation Port Trunking. Comprehensive Security The DGS-3120 Series provides users with the latest security features such as Multi-layer and Packet Content Access Control Lists (ACL), Storm Control, and IP-MAC-Port Binding (IMPB) with DHCP Snooping. The IP-MAC-Port Binding feature allows administrators to bind a source IP address with an associated MAC and also define the port number to enhance user access control. With the DHCP Snooping feature, the switch automatically learns IP/MAC pairs by snooping DHCP packets and saving them to the IMPB white list. In addition, the D-Link Safeguard Engine identifies and prioritizes “CPU interested” packets to prevent malicious traffic from interrupting normal network flows, and to protect switch operation.

Identity Driven Network Policies
The DGS-3120 Series supports authentication mechanisms such as 802.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control and easy deployment. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each host. In addition, the switch also supports Microsoft® NAP (Network Access Protection). NAP is a policy enforcement technology that allows customers to protect network assets from unhealthy computers by enforcing compliance with network health policies.

Traffic Management for Triple Play
The DGS-3120 Series implements a rich set of multilayer QoS/CoS features to ensure that critical network services like VoIP, video conference, IPTV and IP surveillance are served with high priority. The Traffic Shaping features guarantee bandwidth of these services when the network is busy. With L2 Multicast support, the DGS-3120 shows its ability to handle growing IPTV applications. Host-based IGMP/MLD Snooping allows multiple multicast subscribers per physical interface and ISM VLAN sends multicast streams in a multicast VLAN to save bandwidth and to provide better security to the backbone network. The ISM VLAN profiles allow users to bind/replace the pre-defined multicast registration information to subscriber ports quickly and easily.

Proactive, Effective Network Management
To uphold enterprise customers’ Service Level Agreements (SLA), service providers must reduce the Mean Time to Repair (MTTR) and increase service availability. Ethernet OAM features address these challenges and enable service providers to offer carrier-grade services. The DGS-3120 Series supports industry-standard OAM tools, including IEEE 802.3ah, IEEE802.1ag, and ITU-T Y.1731. Connectivity Fault Management (CFM) provides tools to monitor and troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate network issues, and identify customers affected by network issues.

IPv6 Technology
The DGS-3120 Series is fully compliant with the future IPv6 networks. It supports remote IPv6 manageability from telnet, HTTP, or SNMP. To create secure IPv6 networks, the DGS-3120 Series uses IPv6 ACL, DHCPv6 Snooping and Neighbor Discovery (ND) snooping functions to protect the network from illegal IPv6 clients. The DGS-3120 Series has been certified with IPv6 Ready Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium. The IPv6 Ready Logo Program provides conformance and interoperability of IPv6 products.

D-Link Green Technology
D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DGS-3120 Series implements the D-Link Green Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and cable length detection. The power saving feature automatically powers down ports that have no link or link partner. The Smart Fan feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.

Manageability
D-Link’s Single IP Management (SIM) simplifies and speeds up management tasks, allowing multiple switches to be configured, monitored and maintained from any workstation running a web browser through one unique IP address. This virtual stack is managed as a single object, having all units maintained by one IP address. The DGS-3120 Series also supports standard-based management protocols such as SNMP, RMON, Telnet, Console, Web-based GUI and SSH/SSL security authentication.

Great key board and worth the money
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
I have had this key board for over two years. Still works great with awesome battery life. The feel and design of the key board is great. Feels like I am typing on my MacBook Pro. Easy to par with multiple computers. Every once in a while it will become disconnected to my main computer and I will power off and on to reconnect. I have not had any other issues and would definitely purchase again.

Love this keyboard.
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
It's much like their more expensive model that comes with backlighting. I don't need the backlighting on this one because it's for the office so I'm never typing in the dark. I also like that it just uses regular batteries so between that and the lack of backlighting, the batter life is expected to be phenomenal. Clean looking keyboard and a pleasant typing experience.

Perfect Work Keyboard
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard, Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
This keyboard is perfect and exactly what I needed. I wanted a higher quality wireless keyboard for work and this one is that plus some. Keys are not too loud but also not silent. The keyboard itself is thin but not too thin and has weight to it. Also love the ability to connect to other computers with the press of a button. I have a PC for work and Mac for personal use, it switches fast and easy without fail. It’s a little more of an upfront cost compared to others available but it’s worth it truly. Plus the Logi brand itself has gained my trust as all of my other tools (headset, mouse, and webcam) are all Logi and have been excellent. If you’re on the fence due to the price, just purchase and know you’ll never have to buy another keyboard again.

Great keyboard for my mother.
Color: Off White, Style: Battery Powered, Pattern Name: Keyboard, Color: Off White, Style: Battery Powered, Pattern Name: Keyboard
I wanted to move my mother away from corded keyboards so I gave her my old mouse and this keyboard. Functions well with a Linux machine although you have to pair any mice with it on a Windows or Mac computer. It's quite responsive and connects well. A valuable purchase that has survived some falls now. Very durable as long as you're not purposely trying to break it.

Good quality keyboard
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
The Logitech Slim K950 Wireless Keyboard works great as a replacement for my old Logitech USB keyboard, but it's not perfect: Pros: Logitech is a good brand that lasts a long time, very easy to connect via Bluetooth (ready to use in minutes) but also comes with a USB to connect manually; runs on two AAA batteries (have not had to replace yet in over a month); Slim profile with low-profile keys; no problems with the functions on the keyboard so far; it's a regular width keyboard with convenient number pad. Cons: It is a bit pricey compared to some other Bluetooth keyboards; the volume keys are above the backspace bar and sometimes I hit those instead of backspace; the main issue for me is that it is supposed to have keys that are "quiet typing" - I don't like "clicky" keyboards and this one still clicks if I am typing fast or pressing hard. Not as much as other non-silent keyboards, but enough that I notice. That said, I tried a couple different "silent" keyboards and they really were not that much different, so maybe it's just me! Overall this is a good keyboard and I would purchase Logitech again.
