FAQs

Q: What is the difference between the R3A, R3AM, and R3AK models?
A: The R3A provides standard Layer 2/3 features. The R3AM adds TunnelSec encryption capabilities. The R3AK variant includes both TunnelSec and FlexRoute support for large routing tables over 5 million routes, making it ideal for internet peering and MPLS deployments.

Q: What optics are compatible with the QSFP-DD ports?
A: The 400G QSFP-DD ports support a wide range of transceivers including 400G, 200G, 100G, and 50G optics and DAC/AOC cables. Ports can be configured for breakout modes. Refer to Arista's transceiver compatibility matrix for specific module support.

Q: Is this switch suitable for spine or leaf deployment?
A: Yes, the DCS-7280DR3AK-54-F is designed as a universal spine and leaf switch. Its 21.6 Tbps capacity, deep buffers, and high port density make it ideal for both roles in modern data center fabrics supporting MLAG, ECMP, and EVPN-VXLAN architectures.

Q: What software features are included with Arista EOS?
A: Arista EOS provides a modular Linux-based operating system with support for advanced routing protocols (BGP, OSPF, IS-IS), network virtualization (VXLAN, EVPN), MPLS, Segment Routing, precision timing (PTP, SyncE), and comprehensive automation via REST APIs, Python scripting, and zero-touch provisioning.

Q: Does this model require additional licensing?
A: The DCS-7280DR3AK-54-F includes base EOS functionality. Advanced features like CloudVision as-a-Service for centralized management and telemetry may require separate subscription licensing. Contact Arista or your reseller for specific licensing requirements.
