FAQs

Q: What is the difference between the DCS-7280CR3K-32D4-FLX-F and the standard DCS-7280CR3K-32D4-F?
A: The FLX-F model includes the FLX-Lite software license, which enables advanced routing features including support for over 256K routes, full MPLS LSR capabilities, EVPN, VXLAN, and Segment Routing. The standard model requires separate licensing for these advanced features.

Q: Can this switch support breakout configurations for higher port density?
A: Yes, the QSFP28 100G ports support breakout to 4x25G or 4x10G on alternate ports, and the QSFP-DD 400G ports can be configured for 2x200G or 4x100G, providing flexible port density options up to 96 total interfaces depending on configuration.

Q: What deployment scenarios is the 7280CR3K-32D4-FLX-F best suited for?
A: This switch is ideal for data center spine and leaf architectures, high-performance storage networks, content delivery networks, cloud service provider infrastructure, and AI/ML compute clusters requiring high-bandwidth, low-latency connectivity with deep packet buffers and advanced routing capabilities.

Q: Does this model support MACsec or IPsec encryption?
A: No, the DCS-7280CR3K-32D4-FLX-F does not include hardware encryption capabilities. For line-rate MACsec, IPsec, or TunnelSec encryption, consider the 7280CR3MK models which feature integrated encryption hardware.

Q: What is included with the switch and what accessories might be needed?
A: The switch includes dual 1000W AC power supplies, fan modules, and rack mount hardware. You will need to purchase network transceivers (QSFP28, QSFP-DD) and power cables separately. The switch requires standard C13-C14 power cables for the 1000W PSUs.
