FAQs

Q: What is included with the FLX license tier on this model?
A: The FLX license includes full Layer 3 routing with support for over 256K routes, advanced MPLS LER/LSR capabilities, EVPN, VXLAN, Segment Routing, and expanded ACL capacity beyond 24,000 entries. It enables large-scale service provider and data center interconnect applications.

Q: Can this switch support breakout configurations on the QSFP ports?
A: Yes, the 32x 100GbE QSFP28 ports support breakout configurations to 4x25G or 4x10G using appropriate transceivers and cables, allowing flexible connectivity options up to 96 total lower-speed interfaces depending on the application.

Q: What routing table sizes and profiles are supported?
A: The 7280CR3K-32D4A supports large route profiles with over 256K IPv4 routes. Arista FlexRoute architecture enables flexible forwarding profiles optimized for different use cases including internet peering, carrier edge, spine-leaf data centers, and DCI applications.

Q: Is this switch suitable for VXLAN and EVPN overlay deployments?
A: Absolutely. The switch is designed for modern overlay networks with native support for VXLAN encapsulation, EVPN control plane, Segment Routing, and MPLS. The 8GB packet buffer ensures lossless forwarding for storage and real-time applications.

Q: What is the difference between the -R and -F suffix models?
A: The -R suffix indicates rear-to-front (reverse) airflow, where air is drawn from the fan side and exhausted toward the port side. The -F model has front-to-rear airflow. Select the model that matches your data center hot aisle/cold aisle configuration for optimal cooling efficiency.
