FAQs

Q: What encryption capabilities does the DCS-7280DR3AM-36-DC-F support?
A: This model features Enhanced MACsec with Arista TunnelSec technology, providing line-rate AES-256-GCM encryption. It supports IEEE 802.1AE MACsec for point-to-point Layer 2 encryption, IPsec for Layer 3 encrypted tunnels, and VXLANsec for overlay network encryption across all port speeds from 10G to 400G.

Q: What are the power supply specifications for this switch?
A: The DCS-7280DR3AM-36-DC-F comes with dual hot-swappable DC power supplies, each rated at 2400W, providing 1+1 redundancy for continuous operation. The DC power option is ideal for data centers with DC power infrastructure.

Q: Can the 400GbE ports be configured for lower speeds?
A: Yes, the 36x 400GbE QSFP-DD ports support flexible breakout configurations. Ports can be configured for 400G, 200G, 100G, 50G, 40G, 25G, and 10G speeds using appropriate transceivers and cables, enabling versatile deployment scenarios.

Q: What network architectures is this switch designed for?
A: The 7280R3A series is designed for high-performance leaf-spine data center fabrics, cloud networking, data center interconnect (DCI), internet peering, service provider edge networks, and AI/ML infrastructure. It supports EVPN-VXLAN overlays, MPLS, Segment Routing, and traditional Layer 2/Layer 3 architectures.

Q: Does this model require a software license?
A: The switch runs Arista EOS, which includes comprehensive Layer 2 and Layer 3 features. Advanced encryption features (TunnelSec including IPsec and VXLANsec) may require separate EOS licensing. Contact Arista or an authorized reseller for specific licensing requirements for your deployment.
