FAQs

Q: What does the 'M-FLX' designation mean in this model?
A: The 'M' indicates expanded memory for larger routing tables, while 'FLX' denotes the FlexRoute license tier that enables full routing up to 2M routes with advanced features including OSPF, ISIS, BGP, PIM, EVPN, VXLAN, Segment Routing, and advanced MPLS LER/LSR with traffic engineering.

Q: Can this switch support 100G and 200G optics in the 400G ports?
A: Yes, the QSFP-DD ports are backward compatible with 100G QSFP28 and 200G QSFP56 transceivers, and support breakout configurations for multiple lower-speed connections (4x100G, 2x200G, or 8x50G per 400G port).

Q: What deployment scenarios is the 7280R3 Series best suited for?
A: The 7280R3 Series is ideal for high-performance data center spine architectures, internet peering routers, content delivery networks, IP storage fabrics, and data center interconnect (DCI) applications that require deep buffering, lossless forwarding, and internet-scale routing tables.

Q: Does this model support MACsec encryption?
A: The standard DCS-7280DR3-24-M-FLX-F does not include MACsec. MACsec-enabled variants are available in the 7280R3M series with the 'M' suffix indicating MACsec support (different from the '-M' which indicates expanded memory).

Q: What is the difference between FLX and FLX-Lite licensing?
A: FLX licensing supports up to 2M routes with over 24K ACL entries and advanced MPLS features including traffic engineering. FLX-Lite supports up to 256K routes with base MPLS LSR functionality. The FLX license provides significantly higher scale for service provider and large enterprise environments.
