Arista DCS-7280R4K-32DE-F | 7280R4 32-Port 800GbE Switch, 25.6Tbps, Layer 3

Q: What deployment scenarios is the DCS-7280R4K-32DE-F designed for?
A: This switch is purpose-built for AI/ML spine networks, cloud data center aggregation, high-performance compute clusters, data center interconnect (DCI), IP peering, and service provider edge deployments requiring 800GbE density with deep buffering and large routing tables.

Q: Does this model support encryption and security features?
A: Yes, the 7280R4K series includes TunnelSec technology providing wire-speed encryption across all ports simultaneously without performance penalty. It supports IEEE 802.1AE MACsec, IPsec (RFC 4303), and VXLANsec using AES-256-GCM cipher, enabling multi-layer security for Layer 2, Layer 3, and overlay networks.

Q: What transceiver types are supported on the QSFP-DD ports?
A: The 32 QSFP-DD ports support a wide range of pluggable optics including 800G, 400G, 200G, 100G, 50G, 40G, and 25G transceivers. The platform is optimized for high-power 400G and 800G ZR/ZR+ coherent DWDM optics with reach up to 120km, as well as standard SR/LR optics and DAC/AOC cables.

Q: What is the difference between 7280R4 and 7280R4K models?
A: The 7280R4K models include enhanced routing scalability with support for over 5 million IPv4 routes (compared to standard models), making them ideal for internet peering, carrier edge, and large-scale EVPN deployments. The 'K' designation indicates large routing table capacity and enhanced encryption capabilities.

Q: What operating system and automation capabilities does this switch include?
A: The switch runs Arista EOS (Extensible Operating System), a single 64-bit Linux-based network OS with stateful fault containment, full access to Linux shell and tools, and support for automation via REST APIs, Python, Ansible, and programmability through bash and C++. EOS provides consistent features across the entire Arista portfolio.
