D-Link 52-Port Metro Gigabit Ethernet Managed Desktop Switch - (DGS-1210-52/ME)

Efficient and resilient Gigabit performance for Metro Ethernet applications. 48 x 10/100/1000BASE-T ports 4 x SFP ports Comprehensive Layer-2 features including Link Aggregation, Port-based Q-in-Q, and VLAN trunking Enhanced network security with IP-MAC Port-Binding (IMPB), Access Control List (ACL), and IEEE 802.1X Embedded 6kV surge protection, sub-50ms recovery ERPS, and Dying Gasp provide optimal reliability Efficient and Resilient For mission-critical environments, the DGS-1210ME Series Metro Ethernet Switches support IEEE 802.1D 2004 edition, 802.1w, and 802.1s Spanning Tree Protocols (STP). The switches also support IEEE 802.3ad link aggregation, increasing bandwidth and redundancy for higher availability. This series furthermore features IEEE 802.1p Quality of Service (QoS), allowing for real-time traffic classification into Weighted Round Robin (WRR) and strict priority levels mapped to eight queues. Advanced traffic classification parameters allow the network to b
