FAQs

Q: What deployment scenarios is the N9K-C9348GC-FXP best suited for?
A: This switch is optimized for data center top-of-rack and aggregation layer deployments. It excels in environments requiring high-density Gigabit Ethernet server connectivity with flexible multigigabit uplinks for spine connections, ACI fabric integration, and cloud-scale network automation.

Q: Does this switch support Cisco ACI and traditional NX-OS modes?
A: Yes, the N9K-C9348GC-FXP runs Cisco NX-OS and supports both standalone NX-OS mode for traditional data center switching and ACI mode for policy-driven automation and fabric integration. It provides native VXLAN, EVPN, and advanced telemetry capabilities in both deployment modes.

Q: What are the uplink options and speeds supported?
A: The switch provides 4 SFP28 ports supporting 1G, 10G, or 25G speeds and 2 QSFP28 ports supporting 40G or 100G speeds, offering flexible high-bandwidth uplink options for aggregation, spine connectivity, or storage network convergence.

Q: Can this switch support LAN and SAN convergence?
A: Yes, the N9K-C9348GC-FXP supports Fibre Channel over Ethernet (FCoE) and can operate ports as 16/32 Gbps Fibre Channel, enabling convergence of LAN and SAN networks for unified fabric deployments and simplified data center infrastructure.

Q: What advanced features are supported for modern data centers?
A: The switch supports comprehensive Layer 2 and Layer 3 features including VXLAN, EVPN, VRF-Lite, advanced QoS, MPLS, wire-rate security ACLs, comprehensive telemetry and analytics, intelligent buffer management, RoCE support for low-latency storage, and programmable automation via NX-API and RESTCONF.
