DGS-3120-24TC Use Case
Data Center Server Farm Aggregation with High-Throughput Switching
In a mid-sized data center, the DGS-3120-24TC-D-Link integrates rack servers via its 20 Gigabit electrical ports and 4 Gigabit optical multiplexing ports, leveraging a 336 Gbps switching capacity and 96 Mpps packet forwarding rate. Its pure three-layer network management design and built-in DHCP server enable segmented VLAN routing and automated IP assignment for virtualized workloads. Outcome: streamlined east-west traffic consolidation, sub-millisecond latency, and simplified server farm management in a single rack-mount chassis.
Enterprise Campus Distribution and DHCP-Enabled Core Switching
At a large corporate campus, the DGS-3120-24TC-D-Link functions as the distribution layer switch, connecting building access points over 20 Gigabit copper ports and 4 Gigabit fiber uplinks. With a 3.36 Tbps switching capacity, 126 Mpps forwarding rate, pure L3 routing, and on-board DHCP server, it centralizes VLAN-to-VLAN routing and dynamic IP provisioning for 1,500+ endpoints. Outcome: enhanced network stability, elimination of broadcast storms, accelerated deployments, and reduced operational overhead.
ISP Metro Edge Aggregation with Scalable Subscriber Management
An urban ISP deploys the DGS-3120-24TC-D-Link at its metro edge to aggregate customer fiber circuits via 4 Gigabit SFP ports and deliver copper-based services through 20 Gigabit electrical interfaces. Its robust L3 switching capacity and integrated DHCP server assign subscriber IPs on-the-fly, enforce VLAN segmentation, and prioritize VoIP/IPTV traffic. Outcome: scalable, high-throughput subscriber provisioning, consistent QoS during peak hours, and simplified edge-site maintenance in a rack-mount form factor.
