Q: What is the difference between the -R and -F airflow variants?
A: The -R suffix indicates rear-to-front airflow where cool air enters from the port side and exhausts from the non-port side, ideal for hot aisle exhaust deployments. The -F variant has front-to-rear airflow for cold aisle intake configurations.

Q: What routing scale does the 7280TR3 series support?
A: The 7280R3 Series supports over 2 million IPv4 LPM routes, over 1.4 million IPv6 LPM routes, and 384K MAC addresses with FlexRoute technology, providing full Internet routing table support with hardware acceleration.

Q: Can this switch be deployed as both a leaf and spine switch?
A: Yes, the DCS-7280TR3-40C6-R is designed for universal leaf and spine deployments in modern data center fabrics, supporting both Layer 2 MLAG and Layer 3 ECMP architectures with up to 512-way load balancing.

Q: What advanced telemetry features are included?
A: The switch includes LANZ congestion analytics, Accelerated sFlow with hardware sampling, Advanced Event Management, DANZ mirroring and filtering, Inband Network Telemetry, IPFIX, and gNMI streaming for comprehensive network visibility.

Q: Does this model support network virtualization and overlay protocols?
