16 10/100/1000Base-T + 4 100/1000Base-T/SFP Ports L2 Management Switch
The DGS-1210 Series Metro Ethernet Switches are a range of switches designed to provide a range of physical interface types, multiple management interfaces, and advanced Layer 2 features. With all of these features combined, the DGS-1210 Series provides a cost-efficient and flexible solution for expanding any business network. 
Seamless Integration
The DGS-1210 Series includes a wide range of port and media types, including 10/100/1000BASE-T RJ-45 ports, 100/1000 Mbps GbE/SFP combo ports, and 100/1000 Mbps SFP ports. The DGS-1210-20 features 4 GbE/SFP combo ports, allowing you to choose the most suitable media type for your requirements. 
Advanced Features
The DGS-1210 Series comes equipped with a complete lineup of L2 features, including IGMP snooping, port mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfers. Network maintenance features include loopback detection and cable diagnostics. Loopback detection significantly speeds up troubleshooting by automatically detecting and shutting down switching loops. The cable diagnostics feature, designed primarily for administrators and customer service representatives, determines the cable quality and quickly discovers errors, allowing for hassle-free diagnostics and maintenance.
Efficient and Resilient Networking
The DGS-1210 Series supports up to 6 kV surge protection on all Ethernet ports, protecting the switch from the damage caused by power surges due to lightning strikes or faulty electrical cabling. The switches also support 
802.3ad Link Aggregation, which allows grouping of multiple ports to provide redundancy and load balancing in mission-critical environments. Combined, the two features ensures the reliability of data transmission in your network.
Security & Authentication
The DGS-1210 Series supports Voice VLAN and Auto Surveillance VLAN Mode, which allows voice and video traffic to be automatically identified and handled differently than regular network traffic. Surveillance Mode detects compatible ONVIF cameras and places them in a surveillance VLAN, allowing a single switch to be used for voice, video, and data, removing the need for dedicated hardware and reducing maintenance costs. Surveillance Mode also includes its own Web UI, making surveillance features easily accessible and simplifying management of your surveillance network.
Advanced Access Control
D-Link’s innovative Safeguard Engine helps to protect the switches against traffic flooding caused by malicious attacks. DGS-1210 Series supports 802.1X port-based authentication, allowing the clients to be authenticated through external RADIUS servers. The Access Control List (ACL) feature helps to enhance network security and helps to protect the internal IT network. To help prevent ARP spoofing attacks, the switch uses packet control ACLs to block invalid packets that contain fake ARP messages.
