Arista DCS-7280CR3MK-32D4A-S-FLX-F | 7280R3 32-Port 100G Switch, 4x 400G QSFP-DD, MACsec

Q: What is the difference between the standard and FLX licensed versions?
A: The FLX license enables full routing functionality with support for over 256K routes, MPLS LSR, EVPN, VXLAN, and Segment Routing. Without the FLX license, routing scale is limited. This SKU includes the FLX license pre-installed.

Q: Does this switch support both 100G and 400G optics simultaneously?
A: Yes, the 32 QSFP ports natively support 100G and 40G optics with breakout capabilities, while the 4 QSFP-DD ports support both 100G QSFP and 400G QSFP-DD optics for flexible deployment scenarios.

Q: What encryption capabilities does the MACsec version provide?
A: This model supports TunnelSec technology on the 32x 100G QSFP ports, providing hardware-accelerated encryption using AES-256-GCM. It supports MACsec for point-to-point encryption, IPsec for encrypted IP tunnels, and VXLANsec for overlay network encryption, all at line rate without performance penalty.

Q: Is this switch suitable for spine or leaf deployment?
A: This switch is ideal for both spine and leaf roles. The high-density 100G ports work well for leaf-to-spine connectivity, while the 400G QSFP-DD uplinks provide scalable spine capacity. The deep packet buffer and large routing table make it excellent for spine layer in large data centers.

Q: What airflow direction does the F suffix indicate?
A: The F suffix indicates front-to-rear airflow, meaning air flows from the port side to the fan side of the switch. This model includes dual redundant AC power supplies optimized for this airflow configuration.
