This supports wire-speed performance across all 96 x 10GbE ports simultaneously, plus 8 x 40GbE uplinks. Latency is 3 microseconds, making it suitable for latency-sensitive applications like HPC and financial trading.

How many MAC addresses and IPv4 routes can this switch handle?

The 7050TX2-128 supports 288,000 MAC address table entries and 144,000 IPv4 routes (plus 208,000 IPv4 host routes). This capacity accommodates large-scale virtualized environments with thousands of VMs and complex multi-tenant routing topologies without performance degradation.

What packet buffer size does the 7050TX2-128 provide?

The 7050TX2-128 features an enhanced 16MB packet buffer with dynamic buffer allocation, optimized for demanding environments with bursty traffic patterns. This is larger than earlier 7050TX models (10MB) and helps prevent packet loss during traffic spikes in data center and HPC workloads.

Does this switch support SDN and programmable networking?

Yes. The 7050TX2-128 supports OpenFlow 1.0, DirectFlow, and eAPI for software-defined networking. It includes VXLAN bridging and routing, VM Tracer for virtual machine tracking, integrated TCPDump packet capture, and optional SSD storage for advanced logging and data capture directly on the switch.

What are the power and cooling specifications?

The switch includes dual redundant 1+1 hot-swappable AC power supplies and 4 N+1 hot-swappable fan modules with reversible airflow (front-to-rear or rear-to-front). Typical power consumption is less than 5 watts per 10GbE port. Operating temperature range is 0–40°C with 5–95% relative humidity tolerance.

What management and monitoring capabilities are included?

Management features include 2 x 10/100/1000 Mbps management ports, 1 RS-232 serial port (RJ-45), 1 USB port, and Blue Beacon LED for system identification. The switch supports sFlow (RFC 3176) for network monitoring, integrated packet capture with TCPDump, and optional SSD for advanced logging and data analytics.

Is the DCS-7050TX2-128-F suitable for leaf-spine data center architectures?

Yes. The 96 x 10GbE ports provide dense leaf connectivity, while 8 x 40GbE QSFP+ uplinks aggregate traffic to spine switches. The 2.56Tbps capacity, 1440 Mpps forwarding, and 3μs latency support high-performance east-west traffic in modern cloud and virtualized data center designs.
