Arista DCS-7280PR3K-24-FLX-F | 7280R3 24-Port 400G OSFP Switch, 9.6Tbps, FLX License

Q: What does the FLX license included with this model enable?
A: The FLX license enables full routing capabilities up to 2 million IPv4 routes, over 24,000 ACL entries, EVPN, VXLAN, Segment Routing, and advanced MPLS LER/LSR functionality with traffic engineering and link/node protection. This makes it suitable for internet peering, DCI, and large-scale data center spine deployments.

Q: Can the 400G OSFP ports be broken out to lower speeds?
A: Yes, each 400G OSFP port supports flexible breakout configurations including 4x100G, 2x200G, and compatibility with 100G QSFP and 25G SFP ports when configured appropriately, providing deployment flexibility for mixed-speed environments.

Q: What makes the deep buffer architecture beneficial?
A: The 16GB dynamic deep buffer with virtual output queue architecture eliminates head-of-line blocking and packet drops even under congestion, ensuring lossless forwarding for demanding workloads like IP storage, real-time traffic, and large-scale data analytics with in-cast traffic patterns.

Q: Is this switch suitable for internet peering or DCI applications?
A: Absolutely. The R3K variant with FLX license supports internet-scale routing tables up to 2 million routes, making it ideal for internet exchange points, DCI gateway roles, and service provider peering environments requiring full BGP routing tables with headroom for growth.

Q: What operating system does this switch run?
A: The switch runs Arista EOS, a modular Linux-based network operating system with state-sharing architecture. It provides advanced automation, telemetry, zero-touch provisioning, RESTful APIs, and seamless integration with Arista CloudVision for centralized management and monitoring.
