Arista DCS-7280CR3K-32D4A-FLX-F | 7280R3 32-Port 100G Switch, 4x 400G QSFP-DD, FLX

Q: What is the FLX license included with this model?
A: The FLX license provides full routing capabilities supporting over 256K routes, EVPN, VXLAN, Segment Routing (SR), and base MPLS LSR functions. This enables advanced Layer 3 routing, MPLS services, and VXLAN overlay networks for enterprise and service provider deployments.

Q: Can the 100G QSFP ports be broken out to lower speeds?
A: Yes, the 32x 100GbE QSFP ports support flexible breakout configurations to 2x 50G, 4x 25G, or 4x 10G, allowing up to 96 total interfaces. This provides deployment flexibility for mixed-speed environments and incremental network expansion.

Q: What deployment scenarios is this switch designed for?
A: The DCS-7280CR3K-32D4A-FLX-F is ideal for data center spine roles, IP fabric architectures, internet peering, cloud interconnect, and service provider edge networks. The large route table, deep buffer, and high-speed uplinks make it suitable for routing-intensive workloads and high-traffic environments.

Q: What does the -F suffix indicate?
A: The -F suffix denotes front-to-rear airflow, where cool air is drawn in from the front (non-port side) and exhausted through the port side. This is designed for cold-aisle containment data center environments where cold air is supplied from the front.

Q: Is this switch compatible with Arista CloudVision?
A: Yes, the switch runs Arista EOS and fully supports CloudVision for centralized network management, telemetry, automation, and zero-touch provisioning (ZTP). CloudVision provides network-wide visibility, change control, and compliance monitoring capabilities.
