Description

The Cisco N9K-C92304QC Nexus 9200 is a high-density 2RU data centre switch delivering 56x 40G QSFP+ ports and 8x 100G QSFP28 uplinks with 6.1 Tbps switching capacity and 4.8 Bpps forwarding rate. Built on Cisco Cloud Scale technology, it supports both NX-OS standalone and ACI fabric modes, making it ideal for spine-leaf architectures, high-performance computing, and cloud-scale environments. Advanced features include VXLAN, EVPN, Segment Routing, MACsec encryption, and line-rate Layer 2/3 capabilities for enterprise and service provider deployments.

Features

Line-rate Layer 2 and Layer 3 forwarding with hardware-based routing
- VXLAN and EVPN support for network virtualisation and multi-tenancy
- Segment Routing (SR-MPLS and SRv6) for traffic engineering
- MACsec encryption for wire-speed security on all ports
- Comprehensive QoS with 8 hardware queues per port, weighted round-robin, and low-latency queuing
- Advanced routing protocols: BGP, OSPF, EIGRP, RIPv2, IS-IS, PIM-SM, SSM, MSDP
- VRF-Lite and VRF support for traffic segmentation
- Stateful Switchover (SSO) and In-Service Software Upgrades (ISSU) for high availability
- Hot-swappable redundant power supplies and fan modules
- Cisco Cloud Scale ASIC with deep packet buffering and sub-microsecond latency
- Comprehensive telemetry and analytics with streaming telemetry support
- Flexible management via CLI, NX-API, SNMP, REST API, Cisco DNA Center, and Cisco ACI APIC
- Support for automation frameworks including Ansible, Python, and Puppet
- IEEE 802.1Q VLAN support with up to 4,094 VLANs
- Spanning Tree Protocol (STP, RSTP, MSTP) and Virtual Port Channel (vPC) for redundancy
- Cisco TrustSec and role-based access control (RBAC) for enhanced security

FAQs

Q: Can the N9K-C92304QC operate in both NX-OS and ACI modes?
A: Yes, the switch supports both Cisco NX-OS standalone mode and Cisco ACI fabric mode. The operating mode is determined by the software image and licensing installed. Switching between modes requires reimaging the switch.

Q: What licensing is required for full Layer 3 functionality?
A: The N9K-C92304QC requires a LAN Enterprise Services license for full Layer 2 and Layer 3 feature enablement in NX-OS mode. For ACI mode, appropriate ACI licenses are required. Licenses are sold separately from the hardware.

Q: Can the 40G and 100G ports be broken out into lower-speed connections?
A: Yes, up to 16 of the 40G QSFP+ ports can be broken out into 64x 10G ports total. The 100G QSFP28 ports support breakout configurations into 4x 25G or 2x 50G connections, providing flexible deployment options.

Q: What is the typical deployment scenario for this switch?
A: The N9K-C92304QC is designed as a spine switch in leaf-spine data centre architectures, supporting high-density 40G/100G deployments. It excels in cloud-scale environments, high-performance computing clusters, AI/ML workloads, and multi-tenant service provider networks requiring ultra-low latency and high throughput.

Q: Is this switch still available for purchase from Cisco?
A: The N9K-C92304QC reached end-of-sale in August 2019. Cisco recommends migrating to newer Nexus 9300 Fixed Spine Switches such as the N9K-C9332C and N9K-C9364C. However, refurbished and certified pre-owned units remain available from authorised resellers with full technical support options.
