L2 Gigabit Metro Ethernet Switch

D-Link DGS-3700 series Metro Switches are designed & purpose-built for Metro Ethernet services for Telecom/Service Providers. Its design is based on field proven experience learnt from multiple Ethernet deployment in Telecoms/Carriers. It supports wide variety of technologies including Ethernet, OAM (Operations, Administration and Maintenance), Double VLAN (Q-in-Q), QoS and Triple play services demanded by Carrier Ethernet networks.

– 8x 10/100/1000Base-T Ports
– 4x Combo 10/100/1000BASE-T /SFP Ports
– IP Multicast Support for Bandwidth- Intensive Applications
– Web-Based Access Control (WAC)
– L2/L3/L4 Multi-Layer Access Control

Flexible Choices

Front panel access to RS-232 console port Grounding, RJ-45 OOB management port, RJ-45 Alarm port, Modular AC/DC power supply unit, Modular Fan & Modular Dust Filter.


External RADIUS/TACACS+ Authentication Support & D-Link Safeguard Engine.

Traffic Monitoring/Bandwidth

Traffic Segmentation, Granular Bandwidth Control Down to 64 Kbps as well as RMON Support & Port Mirroring.

Service Provider Friendly Hardware

D-Link’s DGS-3700 series is designed to be deployed in compact and outdoor Telecom/Carriers cabinet. It has a compact form factor of 210 mm in depth in a 1U rack enclosure with operating temperature of up to 65˚C. Furthermore, to simplify field installation, troubleshooting and maintenance, it has all the access connections located on the front panel.

Robust Software and Security

D-Link DGS-3700 series provides extensive VLAN support including Double VLAN (Q-in-Q), Layer 2 Protocol Tunneling (L2PT), GARP/GVRP and 802.1Q to enhance network security and performance. Bandwidth Control can be flexibly set for each port using pre-defined thresholds to assure a committed level of service for end users. For advanced applications, per-flow bandwidth control allows easy fine-tuning of service types based on specific IP addresses or protocols. Moreover, it has a robust set of multi-layer (L2, L3, L4) QoS/CoS features optimized for Triple-Play Services like Voice over IP (VoIP), Media-on-Demand (MOD), Internet data access and video conferencing. Priority queues for 802.1p/ TOS/DiffServ are supported, with classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP port numbers.

Product Overview

To uphold enterprise customers’ 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. D-Link DGS-3700 series supports industry-standard OAM tools including IEEE 802.1ag Connectivity Fault Management and IEEE802.3ah Ethernet in the First Mile. IEEE 802.1ag protocol 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. IEEE 802.3ah Ethernet in the First Mile protocol provides link-layer OAM discovery, local and remote loopback diagnostics on the link between the customers’ equipment and the service provider network.
