FAQs

Q: What is the difference between the DCS-7280CR2A-60-DC-F and DCS-7280CR2A-60-F?
A: The DCS-7280CR2A-60-DC-F is equipped with dual 1900W DC power supplies, while the DCS-7280CR2A-60-F uses dual AC power supplies. Both models are electrically identical and offer the same 60x 100GbE QSFP28 ports, 12 Tbps throughput, and AlgoMatch features.

Q: Can the 100G QSFP28 ports be broken out to lower speeds?
A: Yes, each 100GbE QSFP28 port supports breakout configurations: 2x50GbE, 4x25GbE, or 4x10GbE per port, providing flexibility for mixed-speed deployments and backward compatibility with existing infrastructure.

Q: What does AlgoMatch provide on this model?
A: AlgoMatch is Arista's hardware-accelerated policy-based forwarding engine that enables advanced traffic steering, DDoS mitigation, and network telemetry at line rate. It works alongside Accelerated sFlow for real-time visibility without impacting forwarding performance.

Q: Is this switch suitable for spine or leaf deployments?
A: The DCS-7280CR2A-60-DC-F is ideal for both spine and leaf roles in modern data center fabrics. Its 12 Tbps capacity, 128-way ECMP, and VXLAN/EVPN support make it well-suited for high-density spine layers, while the 60x 100G ports provide ample bandwidth for leaf-to-spine connectivity.

Q: What routing protocols and overlay technologies are supported?
A: The switch supports full Layer 3 routing including BGP for underlay and overlay, MPLS, Segment Routing (SR-MPLS), EVPN for multi-tenancy, and VXLAN for network virtualization. It also supports 128-way ECMP for load balancing across multiple paths.
