24-Port 10/100/1000Mbps Copper Gigabit Managed Switch + 4 Mini GBIC ports
4 Mini GBIC Slots for Flexible Fiber Connection
The DGS-1216T Smart Switch presents a cost-effective solution for the small and medium business to economically implement high-speed Gigabit packet switching with easy fine tuning of network performance and security. This switch comes with 16 copper Gigabit ports and 2 combo SFP (Mini GBIC) for fiber connection. Port trunks are provided for server deployment and network backbone attachment, while functions important for bandwidth-intensive applications such as Priority Queues and VLANs are supported to enable you to implement Quality of Service (QoS) and security without having to go through complex network management usually found in other managed switches.
Flow Control to Prevent Packet Loss
4 mini GBIC (SFP) slots are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for short, medium or long-distance fiber backbone attachment. Use of the mini GBIC will disable their corresponding built-in 10/100/1000BASE-T connections.
Port Trunks for Aggregated Bandwidths
With low cost per port, port trunks supporting 802.3ad Link Aggregation standard provide an easy and economical alternative solution for server connection to attain Gigabit bandwidth. Up to 8 10/100/1000BASE-T ports can be combined together to create a multi-link load-sharing aggregated bandwidth to a server.
VLANs for Enhanced Security & Performance
VLANs improve security and bandwidth utilization by limiting the broadcast domains and confining intra-group traffic within their segments. To segment up the network, workstations and servers supporting IEEE 802.1Q VLAN Tagging connected to the switch can be grouped into different Virtual LANs (VLANs). The switch also supports GVRP (GARP VLAN Registration Protocol) for automatic VLAN configuration distribution.
Advanced Network Access Management
802.1x features enable user authentication for each network access attempt. Port security features allow you to limit the number of MAC addresses per port in order to control the number of stations for each port. Static MAC addresses can be defined for each port to ensure only registered machines are allowed to access. By enabling both of these features, you can establish an access mechanism based on user and machine identities, as well as control the number of access stations.
Multi-layer Access Control List (ACL)
Access Control Lists (ACL) allow the network administrator to define policies on network traffic control. The switch supports comprehensive and multi-layer ACLs, providing a powerful tool for network management. For example, the switch can be set to block malicious bulk traffic from specific clients (based either on MAC or IP addresses), or during a virus attack. The switch can be set to restrict its flooding based on a virus's unique pattern (TCP/UDP port number).
