Description

The Cisco N9K-C9348GC-FXP-H is a high-performance 1RU data centre switch delivering 48 ports of 100/1000BASE-T connectivity with 4x 1/10/25G SFP28 and 2x 40/100G QSFP28 uplink ports. Built on the Nexus 9300-FX platform, it provides 696 Gbps switching capacity and sub-microsecond latency, making it ideal for top-of-rack deployments in scalable data centres and enterprise networks. Running Cisco NX-OS, it supports both standalone NX-OS mode and Application Centric Infrastructure (ACI) fabric integration with comprehensive Layer 2 and Layer 3 features.

Features

Cisco NX-OS operating system with full Layer 2 and Layer 3 routing
- Application Centric Infrastructure (ACI) ready for automated policy-based deployments
- VXLAN overlay with MP-BGP EVPN control plane for network virtualization
- Wire-rate security and telemetry without performance degradation
- Advanced buffer management with 40MB intelligent system buffer
- Virtual Port Channel (vPC) for active-active link aggregation and redundancy
- Multiple Spanning Tree Protocol (MSTP) with 64 instances
- Hot Standby Router Protocol (HSRP) for first-hop redundancy
- PowerOn Auto Provisioning (POAP) for zero-touch deployment
- Embedded Event Manager (EEM) for automated troubleshooting
- Comprehensive routing protocols: OSPF, BGP, EIGRP, RIP-2, IS-IS
- IPv4 and IPv6 dual-stack support
- Quality of Service (QoS) with 8 hardware queues per port
- Protocol Independent Multicast (PIM) Sparse Mode for efficient multicast
- Switched Port Analyzer (SPAN) and Encapsulated Remote SPAN (ERSPAN)
- 32,000 IGMP snooping groups and 32,000 multicast routes
- Flexible NetFlow and streaming telemetry for network analytics
- Python scripting and Open NX-OS APIs (NETCONF, REST)
- Port breakout support on QSFP28 ports for 4x 10G or 4x 25G
- Field-replaceable power supplies and fan modules for operational continuity

FAQs

Q: What deployment scenarios is the N9K-C9348GC-FXP-H best suited for?
A: This switch is ideal for top-of-rack deployments in data centres requiring high-density 1 Gigabit connectivity with flexible multi-gigabit uplinks. It excels in big data environments, enterprise access layers, and ACI fabric leaf deployments where local Gigabit Ethernet switching is required alongside 25G and 100G spine connectivity.

Q: Can this switch operate in both ACI and standalone NX-OS modes?
A: Yes, the N9K-C9348GC-FXP supports both Cisco Application Centric Infrastructure (ACI) mode for policy-driven automation and standalone NX-OS mode for traditional Layer 2/Layer 3 switching with full routing protocol support including OSPF, BGP, EIGRP, and VXLAN EVPN.

Q: What transceiver speeds are supported on the SFP28 ports?
A: The 4x SFP28 ports support flexible speeds of 1 Gbps, 10 Gbps, and 25 Gbps, allowing migration from legacy 1G SFP to 10G SFP+ and native 25G SFP28 optics. The 2x QSFP28 ports support 40G and 100G operation, with breakout capability for 4x 10G or 4x 25G configurations.

Q: What power supply and cooling options are available?
A: The switch supports dual hot-swappable power supplies in either AC (350W) or DC (440W) configurations. Fan modules are available in port-side intake or port-side exhaust airflow directions, allowing optimal thermal management for hot-aisle or cold-aisle rack deployments.

Q: Does this switch support advanced features like VXLAN and telemetry?
A: Yes, the N9K-C9348GC-FXP supports VXLAN with MP-BGP EVPN control plane for overlay networks, comprehensive streaming telemetry for real-time analytics, and wire-rate security features. It also includes advanced QoS, multicast (PIM-SM), and segment routing capabilities for modern data centre architectures.
