The DGS-3120 x Stack Series switches are enhanced L2 access stackable switches designed to connect end-users in a secure SMB or enterprise network. These switches support physical stacking, multicast, & enhanced security, making them an ideal Gigabit access layer solution. The DGS-3120-24TC/48TC provides 20 or 44 10/100/1000 Mbps Gigabit Ethernet ports, & 4 combo 1000BASE-T/SFP Gigabit Ethernet ports. The DGS-3120-24PC/48PC provides 24 or 48 10/100/1000 Mbps Po E Gigabit Ethernet ports & 4 combo 1000BASE-T/SFP Gigabit Ethernet ports. The DGS-3120-24SC provides 16 SFP Gigabit Ethernet ports & 8 combo 1000BASE-T/SFP Gigabit ports. Each 10/100/1000 Mbps port on the DGS-3120-24PC/48PC supports the 802.3af & 802.3at Power over Ethernet standards. The default power budget for these models is 370 watts & can be expanded to 760 watts with the DPS-700 RPS. The switches are also equipped with an SD Card slot, allowing the user to boot images & upload configuration files directly from an SD Card as well as conveniently save syslog files onto the SD Card.
Standard & Enhanced Images
The DGS-3120 Series is embedded with two different software images
- the Standard Image (SI) & Enhanced Image (EI). The Standard Image provides sophisticated features for campus or enterprise usage. It
Includes:: advanced Quality of Service (Qo S), traffic shaping, L2 multicasting, robust security features, & IPv 6 features which are suitable for next-generation IPv 6 networks or triple play applications over Metro Ethernet*. The Enhanced Image supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, & s Flow.
Enhanced Network Reliability
The DGS-3120 Series targets enterprises, campuses, & customers who require a high level of network security & maximum uptime. They also include other features, such as 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP), & 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), & Broadcast Storm Control, that enhances network resilience. G.8032 Ethernet Ring Protection Switching (ERPS) minimizes the recovery time to 50ms. For load sharing & redundancy backup in a 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 & Packet Content Access Control Lists (ACL), Storm Control, & 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 & 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 & saving them to the IMPB white list. In addition, the D-Link Safeguard Engine identifies & prioritizes CPU interested packets to prevent malicious traffic from interrupting normal network flows, & to protect switch operation.
Identity Driven Network Policies
The DGS-3120 Series supports authentication mechanisms such as 802.1X, Web-based Access Control (WAC), & MAC-based Access Control (MAC) for strict access control & easy deployment. After authentication, individual policies such as VLAN membership, Qo S policies, & 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 Qo S/ Co S features to ensure that critical network services such as Vo IP, video conferencing, IPTV, & IP surveillance are given high priority. Traffic Shaping features guarantee bandwidth for these services when the network is busy. L2 Multicast support enables the DGS-3120 to handle growing IPTV bandwidth requirements. Host-based IGMP/MLD Snooping allows multiple multicast subscribers per physical interface & ISM VLAN sends multicast streams in a multicast VLAN to save bandwidth & 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 & easily.
Proactive, Effective Network Management
To uphold enterprise customers Service Level Agreements (SLA), service providers must reduce their Mean Time to Repair (MTTR) & increase service availability. Ethernet OAM features address these challenges & enable service providers to offer carrier-grade services. The DGS-3120 Series supports industry-standard OAM tools, including IEEE 802.3ah, IEEE802.1ag, & ITU-T Y.1731. Connectivity Fault Management (CFM) provides tools to monitor & troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate network issues, & identify customers affected by network issues.
IPv 6 Technology
The DGS-3120 Series is fully compliant with future IPv 6 networks. It supports remote IPv 6 manageability from telnet, HTTP, or SNMP. To create secure IPv 6 networks, the DGS-3120 Series uses IPv 6 ACL, DHCPv 6 Snooping, & Neighbour Discovery (ND) snooping functions to protect the network from illegal IPv 6 clients. The DGS-3120 Series has been certified with IPv 6 Ready Logo Phase 2 from the IPv 6 forum, a worldwide IPv 6 advocacy consortium. The IPv 6 Ready Logo Program ensures the conformance & interoperability of IPv 6 products.
D-Link Green Technology
D-Link is striving to take the lead in developing innovative & power-saving technology that does not sacrifice operational performance or functionality. The DGS-3120 Series implements D-Link Green Technology, which
Includes:: a power saving mode, Smart Fan, reduced heat, & cable length detection. The power-saving feature automatically powers down ports that are detected to 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, & eco-friendly operation of the switch.
Manageability
D-Links Single IP Management (SIM) simplifies & speeds up management tasks, allowing multiple switches to be configured, monitored, & 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, & SSH/SSL security authentication.
* Supports IPv 6 in firmware R3.0 SI & above.
