D-Link DGS-3130-30TS/B 30-Port Lite Layer 3 Stackable Managed Gigabit

Lite Layer 3 stackable managed switch for a secure enterprise or metro Ethernet access network.

Adaptable, Bottleneck-Free 1G Business Connectivity
The DGS-313 Series is a highly versatile Lite Layer 3 stackable switch. Including powerful L2 & L3 features, as well as support for multiple software images, it is highly pliant, capable of accommodating different network deployments.

With network bottlenecks on the rise, the DGS-313 Series's six 1 Gigabit uplink ports are an ideal solution. Business can flexibly increase their bandwidth with flexibility to incrementally meet growing bandwidth demands.

Highly Reliable
Redundant power supply (RPS) support, Ethernet Ring Protection (ERPS) and 6 kV surge protection on all GE and RJ-45 access ports

Feature-Rich Unified Software
Powerful L2 and L3 features such as Static Route, RIPIPng and OSPFv2/v3

Scalable and Highly Available
Supports high bandwidth stacking and fault tolerant topologies

Easy Access Control
Support for 82.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC)

Weather the Storm
The DGS-313 Series features built-in 6 kV surge protection on all PoE and non-PoE Gigabit Ethernet access ports without needing external surge protection. This effectively protects the switches against sudden electrical surges caused events such as lightning strikes or unstable electrical current. This significantly reduces the chances of equipment being damaged, effectively lowering maintenance costs by minimizing the need for expensive repairs or replacement.

Highly Available. Highly Flexible.
The D-Link DGS-313 Lite Layer 3 Stackable Managed Switches are a Gigabit access layer solution specifically designed to connect end-users in a secure enterprise or metro Ethernet access network.

The switches support high bandwidth, long distance stacking, with physical stacking of up to 9 units over fiber, increasing available Gigabit ports on demand. This makes them ideal for network administrators who demand agile expansion functionality without having to sacrifice network reliability.

Slash Your Network Downtime
The DGS-313 Series gives enterprises and organizations a highly reliable network, allowing for maximum business continuity. It has built-in G.832 Ethernet Ring Protection Switching (ERPS) to help minimize recovery times to 5 ms.

Along with a host of essential network reliability features, all switches in the series support an external redundant power supply to ensure your operations continue unimpeded.

Comprehensive Security
The DGS-313 Series gives your network the protection it deserves with leading-edge security features that handle threats effectively. With built-in IP-MAC-Port Binding, the switches allow administrators to enhance user access control.

Other advanced features like DHCP Snooping let the switches automatically learn and save IP/MAC pairs to the IMPB white list.

Powerful and Unified
Powerful L2 and L3 features such as RIPIPng and OSPFv2/v3 come together in an integrated software image. This allows the switches to satisfy a wide range of requirements for different applications – perfect for building the solid and networks.

Manage Network Traffic in a Whole New Way
The DGS-313 Series implements a rich set of multi-layer QoS/CoS features to prioritize critical network services such as VoIP, video conferences, IPTV, and IP surveillance. With robust features including Traffic Shaping, L2 Multicast, Host-based IGMP/MLD Snooping and ISM VLAN, administrators get a whole new way to manage their traffic that fits their needs.

Flexible Access Control Policies
Strict access control and deployment are made easy with the DGS-313 switches. All support authentication mechanisms such as 82.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC), and allow individual policies to be assigned to each host after authentication. In addition, the switch also supports Microsoft® NAP (Network Access Protection).
