Arista DCS-7132LB-48Y4C-F | 7132LB 48-Port 25G Switch, 4x 100G QSFP28, FPGA

Q: What makes the DCS-7132LB-48Y4C-F ideal for high-frequency trading environments?
A: The switch delivers ultra-low latency of 133ns for Layer 2 and 150ns for Layer 3 forwarding at 25G speeds, leveraging FPGA technology to minimize packet processing delays. It supports IEEE 1588v2 PTP with PPS I/O for precise timestamping and synchronization, critical for financial market data distribution and HFT applications.

Q: Can I develop custom network applications for this switch?
A: Yes. The DCS-7132LB-48Y4C-F includes a Xilinx UltraScale+ VU9P-3 FPGA with full access via Arista's FPGA Development Kit (FDK) and Vitis Development Kit (VDK). These toolkits provide API documentation, sample code, and IP cores to enable custom application development for performance-critical workloads.

Q: What port speeds and configurations are supported?
A: The 48 SFP28 ports support 10GE and 25GE speeds, while the 4 QSFP28 ports support 40GE and 100GE, with breakout capability to 4x 25GE or 4x 10GE per QSFP28 port. The switch provides flexible L2/L3 switching profiles: 48 ports at 10G or 36 ports at 25G.

Q: What licensing is required for this switch?
A: The DCS-7132LB-48Y4C-F belongs to Arista EOS Feature Licenses Group 2. Optional licenses include Enhanced L3 (BGP, OSPF, ISIS, PIM, NAT), Virtualization (VMTracer, VXLAN), FLX-Lite (full routing up to 256K routes, EVPN, VXLAN, SR, base MPLS LSR), and FLX (full routing up to 2M routes with advanced MPLS).

Q: What is the difference between the -F and -R airflow models?
A: The -F suffix indicates front-to-rear airflow (port side intake, exhaust at rear), suitable for standard data center hot aisle/cold aisle configurations. The -R model has rear-to-front airflow for different thermal management requirements. Both include 2x redundant AC power supplies and hot-swappable fans.
