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 8 queues. Advanced traffic classification parameters allow the network to be tuned for flexible configurations for specific multimedia applications such as VoIP or IPTV. The DGS-1210ME Series supports IEEE 802.1X port-based/host-based access control, guest VLAN, and RADIUS/TACACS+ authentication for strict access control to the network. The IP-MAC-Port Binding (IMPB) feature allows administrators to further enhance user access control. The built-in D-Link Safeguard Engine™ helps protect the CPU from broadcast, multicast, and unicast flooding. In addition, the Access Control List (ACL) feature enhances network security and switch performance. Thank you for Shopping at Ovidian Tech Solutions.
