The DGS-3630 Series Layer 3 Stackable Managed Switches are designed for Small Medium Businesses (SMBs), Small Medium Enterprises (SMEs), larger Enterprises, and Internet Service Providers (ISPs). They deliver high performance, flexibility, fault tolerance, and advanced software features for maximum return on investment. With Gigabit Ethernet RJ45 and SFP ports, 10 GbE SFP+ ports, advanced security features, and advanced Quality of Service (QoS), the DGS-3630 switches can operate as core, distribution or access layer switches. High port densities, switch stacking, and easy management make the DGS-3630 Series switches ideal for a wide variety of business networking applications.

Standard and Enhanced Software Images

The DGS-3630 Series switches include the Standard Image (SI) software. For additional functionality, they may be upgraded to Enhanced Image (EI) software with a separately ordered license upgrade. The Standard Image provides core SMB and SME functionality, such as L2 switching, entry-level routing, L2 multicast, advanced QoS, Operations, Administration, and Maintenance (OAM), and robust security features. The Enhanced Image includes all the features from the Standard Image, and adds support for full L3 routing for Enterprise integration, including OSPF, BGP, VRF-Lite and L3 multicast.

This approach allows I.T. managers to deploy a lower cost L2/L2+ solution today, and upgrade to a L3 solution in the future when networking needs change and a full dynamic routing solution is required.

High Availability and Flexibility

The DGS-3630 Series switches support stacking technology, which combines multiple switches to form a single physical or virtual stack. This increases redundancy over multiple physical units, simplifies management, and provides a single IP address to manage all members in the stack. Up to nine switches can be stacked using Direct Attach Copper (DAC) or fiber optic cables to make up to 432 Gigabit Ethernet ports available, allowing switching capacity to be increased with demand. The Switch Resource Management (SRM) feature allows the hardware table sizes to be dynamically changed, so that switch functions can be optimized based on the use of the switch. There are three modes: IP Mode, LAN Mode, and L2 VPN Mode. These modes modify the sizes of the Layer 2 and 3 tables for optimum efficiency.

Switch and Link Failover

In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the DGS-3630 Series switches also support advanced Ethernet failover redundancy technologies, such as ERPS and FlexLink. Ethernet Ring Protection Switching (ERPS) provides millisecond-level failover in a ring topology. FlexLink offers link failover on designated switch ports, providing link redundancy without STP or LBD.

Security, Performance and Availability

The DGS-3630 Series switches provide a complete set of security features including multi-layer Access Control Lists (ACLs) and 802.1X user authentication via TACACS+ and RADIUS. The DGS-3630 switches also offer extensive VLAN support, including GVRP and 802.1Q VLAN to enhance security and performance. A robust set of QoS features help ensure that critical network services such as Voice over IP and video conferencing are given high priority through the network. The D-Link Safeguard Engine increases the switches' reliability, serviceability, and availability by preventing traffic flooding caused by malicious attacks.
