About the Cisco Nexus 9408 Modular Chassis
The Cisco Nexus 9408 employs distributed forwarding with non-blocking switching architecture, delivering enterprise-grade performance for large-scale data center networks. This modular chassis (part number N9K-C9408) provides exceptional port density and flexibility, supporting up to 256 × 400GE ports or up to 1,024 × 100GE ports depending on line-card configuration. Built on Cisco Cloud Scale ASIC technology, the platform handles modern overlay protocols including VXLAN, EVPN (BGP-EVPN), SR-MPLS, and Segment Routing, making it ideal for network engineers deploying advanced fabric architectures.
The 14U modular chassis features 8 line card slots and 2 supervisor slots, with redundant hot-swappable supervisors, power supplies, and fan modules to ensure continuous operation. Cisco Nexus 9000 Series platforms support both NX-OS standalone and Cisco ACI mode, adapting to diverse operational requirements. High availability is reinforced through hitless ISSU (In-Service Software Upgrade) and redundant AC/DC power supply options. Front-to-back and back-to-front airflow cooling provides deployment flexibility. Advanced management capabilities include NETCONF, YANG, gRPC, gNMI, RESTCONF, and streaming telemetry, enabling seamless integration with modern DevOps and network automation workflows. Software features encompass VXLAN routing and bridging, EVPN multi-homing, dynamic routing protocols (OSPF, ISIS, BGP, PIM, IGMP), and MACsec encryption support (line-card dependent).
Typical Enterprise Deployment Scenarios
- Large-scale data center core and leaf fabric requiring high-density 400GE interconnects
- Multi-tenant cloud environments leveraging EVPN and VXLAN overlay technologies
- Service provider networks implementing Segment Routing and BGP-EVPN designs
- Mission-critical deployments demanding hitless upgrades and redundant supervision
- Automated infrastructure requiring streaming telemetry and model-driven programmability
