FAQs

Q: What licensing is included with the DCS-7280DR3K-24-FLX-F?
A: The FLX suffix indicates the FLX license is pre-installed, providing full routing capabilities with up to 256K routes, advanced MPLS LER/LSR features with traffic engineering, EVPN, VXLAN, Segment Routing, and over 24K ACL entries. No additional routing licenses are required.

Q: Can the 400G QSFP-DD ports be broken out to lower speeds?
A: Yes, each 400G QSFP-DD port supports flexible breakout configurations including 4x100G, 2x200G, 8x50G, and other combinations depending on transceiver and cable support, allowing up to 96 ports of 100G connectivity.

Q: What are typical use cases for the 7280DR3K-24?
A: This switch is ideal for data center spine deployments, internet peering with large BGP routing tables, high-performance storage networks requiring lossless forwarding, data center interconnect, and service provider edge routing with MPLS and Segment Routing.

Q: What is the difference between the 7280DR3 and 7280DR3K models?
A: The K designation indicates large route table support. The 7280DR3K models support over 256K routes with flexible forwarding profiles optimized for internet peering and carrier routing, while standard 7280DR3 models have smaller routing tables suitable for typical data center applications.

Q: Does this switch support lossless Ethernet for storage workloads?
A: Yes, the 7280DR3K-24 features 16GB of dynamic deep buffering with Virtual Output Queues per port to eliminate head-of-line blocking, making it ideal for lossless forwarding in IP storage, data analytics, and high in-cast traffic scenarios.
