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-3120-48PC provides 48 PoE 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.
D-Link's 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 prioritises "CPU interested" packets to prevent malicious traffic from interrupting normal network flows, and to protect switch operation.
