FAQs

Q: What is the difference between the FLX-R and standard models?
A: The FLX-R model includes the FLX-Lite license preinstalled, which supports up to 256K IPv4 routes, EVPN, VXLAN, segment routing, and base MPLS LSR functionality. The -R suffix indicates rear-to-front airflow, suitable for hot-aisle containment data center designs.

Q: Can the QSFP28 ports be used for 10G or 25G connectivity?
A: Yes, each QSFP28 port supports breakout configurations to 4x10G or 4x25G using appropriate breakout cables or transceivers, allowing up to 80 total usable ports in a single 1RU switch.

Q: What routing protocols are supported on this switch?
A: The DCS-7280SR3-48YC8-FLX-R supports comprehensive Layer 3 routing protocols including BGP, OSPF, IS-IS, PIM, static routing, VXLAN, EVPN, segment routing, and MPLS LSR functionality as part of the FLX-Lite license.

Q: Is this switch suitable for spine-leaf data center fabrics?
A: Yes, this switch is commonly deployed at the leaf layer in spine-leaf architectures, providing high-density 25G server connectivity with 100G uplinks to the spine, supporting modern VXLAN EVPN overlay networks and traditional Layer 3 fabrics.

Q: Does this switch support network automation and programmability?
A: Yes, the switch runs Arista EOS with full Linux shell access, supporting modern automation through REST API, NetConf, gRPC, OpenConfig, CloudVision integration, and native Python scripting for DevOps workflows.
