D-Link DGS-3120-24TC 24-port xStack Layer 2 Stackable Gigabit Switch

D-Link's DGS-3120 xStack Series are enhanced L2 access stackable switches designed to connect end-users in a secure SMB or enterprise network. These switches support physical stacking, multicast and enhanced security, making them an ideal Gigabit access layer solution. The DGS-3120-24TC provides 20 Gigabit ports and 4 combo SFP ports. This switch is also equipped with an SD Card slot, allowing the user to boot images and upload configuration files directly from an SD Card.

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 small and medium businesses, including 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. The DGS-3120 Series targets small and medium businesses that 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 Spanning Tree, Rapid Spanning Tree and Multiple Spanning Tree, Loopback Detection, and Broadcast Storm Control, which enhance network resilience. The Ethernet Ring Protection Switching (ERPS) function minimises the recovery time in case of a loop failure. For load sharing and redundancy backup in switch cascading/server attachment configuration, the DGS-3120 Series provides dynamic port trunking.
