FAQs

Q: What is the FLX license included with this switch?
A: The FLX license provides full routing capabilities up to 256K routes with support for EVPN, VXLAN, Segment Routing, and base MPLS LSR functionality. This license tier is ideal for data center spine/leaf deployments requiring advanced routing without the need for traffic engineering or link protection features available in higher-tier licenses.

Q: What breakout configurations are supported on the 400G OSFP ports?
A: Each 400GbE OSFP port can be configured as a single 400G interface, 4x 100G, 8x 50G, or 4x 25G through breakout cables and transceivers. This provides up to 96x 100G ports maximum when all ports are broken out, offering exceptional deployment flexibility.

Q: What is the difference between the M-FLX-F and standard models?
A: The M designation indicates expanded memory (64GB system RAM vs. standard 8GB) and includes an SSD for enhanced storage capacity. The FLX suffix includes the FLX routing license, and the F indicates front-to-rear airflow with dual 1500W AC power supplies pre-installed.

Q: Is this switch suitable for spine or leaf deployment?
A: Yes, the 7280PR3-24 is designed for both spine and leaf roles in modern data center architectures. The 16GB deep packet buffer and 256K route capacity make it particularly well-suited for spine deployments, while the high port density and low latency support leaf deployments for server connectivity and storage networks.

Q: What routing protocols are supported with the FLX license?
A: The FLX license supports BGP, OSPF, IS-IS, PIM for multicast, EVPN for overlay services, VXLAN encapsulation, Segment Routing, and base MPLS Label Switched Router (LSR) functionality. It provides comprehensive Layer 2 and Layer 3 routing for enterprise and service provider environments.
