With the DHCP Snooping feature, the switch automatically learns IP/MAC pairs by snooping DHCP packets and saving them to the IMPB white list. The IP-MAC-Port Binding feature allowsĪdministrators to bind a source IP address with an associated MAC and also define the port number to enhance user access control. 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 (IMPB) with DHCP Snooping. 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 G.8032 Ethernet Ring Protection Switching (ERPS) function minimizes the recovery time to 50 ms. The DES-3810-28 and DES-3810-52 both support an external redundant power supply so that continued operation is assured. They also include other features, such as 802.1D 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 DES-3810 Series targets enterprise/campus and customers who require a high level of network security and maximum uptime. This allows users to optimize the switch resources for different networking environments. In addition, the Enhanced Image also supports Switch Resource Management (SRM). It includes advanced Quality of Service (QoS), traffic shaping, 802.1Q tunneling (Q-in-Q), IPv4 routing/multicasting, Ethernet OAM, and various other security features. The Enhanced Image supports IPv6 routing, Border Gateway Protocol (BGP), and Multi Protocol Label Switching (MPLS), which is suitable for next-generation IPv6 networks or VPN/triple play applications in Metro Ethernet. The Standard Image provides sophisticated features for campus or enterprise. The DES-3810-52 Series is embedded with two different software images - Standard Image (SI) and Enhanced Image (EI). The combo ports provide users with a much higher level of flexibility for dedicated trunk connections between devices or core switches. The Fast Ethernet ports allow users to connect to other LAN access switches. The DES-3810-52 provides 48 10/100 Fast Ethernet ports, 2 1000Base-T and 2 combo1000Base-T/SFP Gigabit Ethernet ports. The DES-3810-52 Series 24 and 48-port switches are the latest additions to the D-Link xStack family of nextgeneration, high-end, multi-service Layer 3 switches. The DES-3810-28 provides 24 10/100 Mbps Fast Ethernet ports and 4 combo 1000Base-T/SFP Gigabit Ethernet ports. Since the loopback module does not contain laser diodes, photodiodes, laser driver or transimpedance amplifier chips, etc., it provides an economical way to exercise QSFP28 ports during R&D validation, production testing and field testing.48-Port 10/100Mbps + 4 Combo 1000BASE-T/SFP 元 Managed Switch DES-3810-52 *(This product has been discontinued) Transmit data from the host is electrically routed (internal to the loopback module) to the receive data outputs and back to the host. QSFP28 loopback is packaged in a standard MSA housing compatible with all QSFP28 ports. Attenuation options are available in nominal and attenuated versions including 0db, 3.5db and 5db power options are 1W, 2.5W, 3.5W plug in and out can reach to 500times. By substituting for a full-featured QSFP28 transceiver, the electrical loopback provides a cost effective low loss method for QSFP28 port testing. QSFP28 passive electrical loopback is used for testing QSFP28 transceiver ports in board level test. The QSFP+ loopback provides power Class 1, 2, 3 or 4 loading using a customer supplied +3.3V voltage supply. Since the loopback module does not contain laser diodes, photodiodes, laser driver or transimpedance amplifier chips, etc., it provides an economical way to exercise QSFP/QSFP+ ports during R&D validation, production testing, and field testing. QSFP/QSFP+ is packaged in a standard MSA housing compatible with all QSFP/QSFP+ ports. Attenuation options are available in nominal and attenuated versions including 0db, 3.5db and 5db power options are 1W, 2W, 3.5W plug in and out can reach to 500times. By substituting for a full-featured QSFP/QSFP+ transceiver, the electrical loopback provides a cost effective low loss method for QSFP/QSFP+ port testing. QSFP/QSFP+ passive electrical loopback is used for testing QSFP/QSFP+ transceiver ports in board level test.
