FAQs

Q: What is the FLX license on this model?
A: The FLX license enables full Layer 3 routing capabilities with up to 2 million routes, advanced ACLs, EVPN, VXLAN, Segment Routing, and advanced MPLS features including LER and LSR functionality for carrier-grade deployments.

Q: Can this switch support mixed port speeds?
A: Yes, the 36x QSFP28 ports flexibly support 1G, 10G, 25G, 40G, 50G, and 100G interfaces using appropriate transceivers and breakout cables. The 2x 400G QSFP-DD ports support 100G, 200G, and 400G.

Q: What is the -R suffix in the SKU?
A: The -R suffix indicates rear-to-front airflow, meaning air is drawn from the port side and exhausted through the fan/PSU side. This is ideal for cold-aisle containment data center designs.

Q: Is this switch suitable for spine or leaf deployment?
A: The 7280CR3-36S is well-suited for both leaf and spine roles in data center fabrics, with high-density 100G connectivity for leaf nodes and 400G uplinks for spine aggregation, plus robust EVPN/VXLAN support for overlay networks.

Q: What protocol support is included for network virtualization?
A: The switch includes comprehensive support for VXLAN routing and bridging, EVPN control plane, Segment Routing (SR-MPLS and SRv6), MPLS VPN services, and large-scale MAC and ARP tables for multi-tenant environments.
