The DES-3810 series is a new member of the D-Link xStack family of next-generation, high-end, multiservice Layer 3 switches and consists of 24 and 48-port switches. The DES-3810-28 provides 24 10/100 Mbps Fast Ethernet ports and 4 combo 1000Base-T/SFP Gigabit Ethernet ports. The DES-3810-52* provides 48 10/100 Mbps Fast Ethernet ports, 2 1000Base-T and 2 combo 1000Base-T/SFP Gigabit Ethernet ports. The Fast Ethernet ports allow users to connect to other LAN access switches. The combo ports provide users a much higher level of flexibility for dedicated trunk connection between devices or core switches.
Standard and Enhanced Images
The DES-3810 series is embedded with two different software images - Standard Image (SI) and Enhanced Image (EI). The Standard Image provides sophisticated features for campus or enterprise. It includes advanced Quality of Service (QoS), traffic shaping, 802.1Q tunneling (Q-in-Q), IPv4 routing/multicasting, Ethernet OAM and various security features. The Enhanced Image supports IPv6 routing, Border Gateway Protocol (BGP), and Multi Protocol Label Switching (MPLS) which is suitable for the next generation IPv6 networks or VPN/triple play applications in Metro Ethernet. In addition, the Enhanced Image also supports Switch Resource Management (SRM). This allows users to optimize the switch resources for different networking environments.
Enhanced Network Reliability
The DES-3810 series targets enterprise/campus and customers who require a high level of network security and maximum uptime. The DES-3810-28 and DES-3810-52 both support external redundant power supply so that continued operation is assured. Other features include 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and Broadcast Storm Control that enhance network resilience. The G.8032 Ethernet Ring Protection Switching (ERPS) function minimizes the recovery time to 50 ms. For load sharing and redundancy backup in switch cascading/server attachment configuration, the DES-3810 series provides dynamic 802.3ad Link Aggregation Port Trunking.
The DES-3810 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 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 prioritizes “CPU interested” packets to prevent malicious traffic from interrupting normal network flows and protects switch operation.
Identity Driven Network Policies
The DES-3810 series supports authentication mechanisms such as 802.1X, Web-Based Access Control (WAC), and MAC-Based Access Control for strict access control and easy deployment. After authentication, individual policies such as VLAN membership, QoS policies, and 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 Services
The DES-3810 series implements a rich set of multilayer QoS/CoS features to ensure that critical network services like VoIP, video conference, IPTV and IP surveillance are served with priority. The Three Color Marker and Traffic Shaping features guarantee bandwidth of these services when the network is busy. With L2/L3 Multicast support, the DES-3810 shows its ability to handle the growing IPTV applications. The host-based IGMP/MLD Snooping allows multiple multicast subscribers per physical interface and ISM VLAN sends multicast streams in a multicast VLAN to save bandwidth and 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 and easily.
Proactive, Effective Network Management
To uphold enterprise customers’ Service Level Agreement (SLA), service providers must reduce the Mean Time to Repair (MTTR) and increase service availability. Ethernet OAM features address these challenges and enable service providers to offer carrier-grade services. The DES-3810 series supports industry-standard OAM tools including IEEE 802.3ah, IEEE802.1ag, and ITU-T Y.1731. Connectivity Fault Management (CFM) provides tools to monitor and troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate network issues, and identify customers affected by network issues.
High Performance Routing
The DES-3810 series supports hardware-based, wire speed L3 routing functions. For small networks, the inter-VLAN routing, static routing and Routing Information Protocol (RIP) provide an easy way to configure your L3 routing environment. For mid-tolarge networks, the Open Shortest Path First (OSPF) and Border Gateway Protocol Version 4 (BGPv4) are supported for better routing performance. The Policy-based Routing (PBR) allows administrators to control the direction of dynamic routing either for load balance or security reason.
For L3 multicasting, the DES-3810 series supports rich Protocol Independent Multicast (PIM) protocols including PIM Sparse Mode (PIM-SM), PIM Dense Mode (PIM-DM), PIM Source-Specific Multicast (PIM-SSM), and PIM Sparse-Dense mode (PIMSDM).
Inter-operating with IPv4 and IPv6
The DES-3810 series is fully compliant with the future IPv6 networks. It supports remote IPv6 manageability from telnet, HTTP, or SNMP. It also supports the IPv6 dynamic routing protocols such as RIPng and OSPFv3. Additionally, this device supports IPv4/v6 dual stack and IPv6 tunneling functions, allowing the DES-3810 to play the role of a bridge between IPv4 and IPv6 network.
For the security of next generation IPv6 networks, the DES-3810 series enables IPv6 ACL, IPv6 RADIUS, DHCPv6 Snooping and Neighbor Discovery (ND) Snooping functions to protect the network from illegal IPv6 clients.
VPN Tunnel Service For Enterprises
The DES-3810 series is also built as a telecom access switch. It supports many advanced features such as VLAN translation, Selective Q-in-Q and Virtual Private Wire Service (VPWS) that allows users to create L2 VPN tunnels through the telecom MPLS backbone. With the L2 Protocol Tunneling (L2PT) function, the DES-3810 provides L2 transparency to business subscribers through the ISP network which helps reduce IT expenses by centralizing the network management.
