Cisco N9K-C9348GC-FX3 | Nexus 9300-FX3 48-Port Gigabit Switch, 4x 25G SFP28, 2x 100G QSFP28

Q: What operating modes does the N9K-C9348GC-FX3 support?
A: The switch supports two modes: Cisco Application Centric Infrastructure (ACI) for centralized automation and policy-based management, or standalone Cisco NX-OS mode for traditional CLI-based configuration and operation.

Q: Can the uplink ports support multiple speeds?
A: Yes. The 4x SFP28 ports support 1G, 10G, or 25G speeds, and the 2x QSFP28 ports support 40G or 100G. Breakout cables can split higher-speed ports into multiple lower-speed connections for deployment flexibility.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Absolutely. The N9K-C9348GC-FX3 is designed as a leaf switch for modern data center fabrics, providing high-density Gigabit access with flexible 25G/100G uplinks to spine switches, along with VXLAN EVPN and Layer 3 routing capabilities.

Q: Does the switch support advanced data center features?
A: Yes. It includes VXLAN for network virtualization, EVPN for Layer 2/3 overlay, MACsec encryption, comprehensive telemetry, ISSU for zero-downtime upgrades, and advanced QoS for congestion management in AI/ML workloads.

Q: What is the difference between the FX3 and earlier Nexus 9300 models?
A: The FX3 series is built on Cisco Cloud Scale ASIC technology, offering enhanced scalability, increased endpoint capacity, wire-rate security, advanced telemetry, and optimized performance for modern data center and cloud applications compared to earlier generations.
