Arista DCS-7280CR3-32P4-M-FLX-R | 7280R3 32-Port 100G Switch, 4x 400G OSFP, 4.8Tbps

Q: What does the FLX license include on this model?
A: The FLX license provides full Layer 3 routing with support for over 256K routes, EVPN, VXLAN, Segment Routing, and advanced MPLS LSR/LER capabilities. It enables enterprise-grade routing features for large-scale data center and service provider deployments without additional licensing costs.

Q: What is the difference between the M and standard versions?
A: The M designation indicates expanded memory, providing enhanced capacity for larger routing tables, ACLs, and forwarding entries. This makes it ideal for internet peering, carrier edge, and complex enterprise networks requiring higher scale than standard models.

Q: Can the 400G OSFP ports support lower speeds?
A: Yes, the 400GbE OSFP ports are flexible and can be configured to support 100GbE, 200GbE, and 400GbE connections depending on the optics used, providing investment protection and deployment flexibility.

Q: What is the rear-to-front airflow configuration used for?
A: The R suffix denotes rear-to-front airflow, designed for hot aisle exhaust deployments where cool air enters from the port side and hot air exits from the rear. This must match your data center cooling architecture for optimal thermal management.

Q: Does this switch support data center interconnect applications?
A: Yes, with 4.8Tbps capacity, deep buffers, VXLAN, EVPN, and Segment Routing support, the 7280CR3 is well-suited for DCI, spine-leaf architectures, internet peering, and high-performance storage networks requiring lossless forwarding.
