D-Link 52-Port Metro Ethernet Gigabit Smart Managed Switch | 48 GbE + 4 SFP Ports | L2+ | VLANS | Fanless (DGS-1210-52/ME)

The DGS-1210/ME Series Metro Ethernet Switches are a family of switches designed for Metro Ethernet applications. They feature a variety of port configurations, including 10/100/1000BASE-T RJ-45 ports, with and without PoE support, and 1G SFP optical ports. They can be managed with a Command Line Interface (CLI) or user-friendly web-based Graphical User Interface (GUI). Surge protection, advanced Layer 2 functions, and a suite of security and management tools make the DGS-1210/ME switches ideal for Enterprises and Service Providers requiring additional capabilities beyond those found in a traditional Smart managed switch. For mission critical environments, the DGS-1210/ME switches support IEEE 802.1D 2004 edition, 802.1 w, and 802.1 s Spanning Tree Protocols (STP).

The Spanning Tree Protocols allow the switches to participate in Spanning Tree topology, providing an alternative Layer 2 path in the event of a network failover. The switches also support IEEE 802.3 ad link aggregation, which enables multiple ports to be grouped to form a single virtual port, increasing bandwidth and redundancy for higher availability. This series also features IEEE 802.1 p Quality of Service (QoS), allowing for real-time traffic classification into Weighted Round Robin (WRR) and strict priority levels mapped to 8 queues.
