Cisco Nexus 9408 Switch Chassis

The Cisco Nexus 9400 Series centralized modular switches expand the Cisco Nexus 9000 Series portfolio with a new chassis that supports very high port-density 400 Gigabit expansion modules.

As data centers continue to evolve to support next-generation applications such as machine learning that drive massive growth in intra-data-center traffic bandwidth, data-center operators require compact, high-capacity, and highly efficient switches to upgrade data-center fabrics. They need security, automation, visibility, analytics, and assurance. Equipped to support this next-generation cloud architecture, the Cisco Nexus 9400 series switches are based on Cisco Cloud Scale technology.

The Cisco Nexus 9400 series centralized modular architecture can scale up to 25.6 Tbps with a combination of field-replaceable switch cards, expansion modules, power supplies, and fans.

The Cisco Nexus 9400 Series Switch has a new design with a height of 4 rack units and a depth of 24 inches including 8 expansion slots to support 64 ports of 400G, or 128 ports of 200G, or 176 ports of 10/25/50G, with MACsec capability on all ports.

Furthermore, the chassis architecture supports a supervisor and up to 8 expansion modules, fan tray redundancy with 5 fan trays, and power supply redundancy.

The Cisco Nexus 9400 series supports Precision Time Protocol (PTP) with Class C timing accuracy for telecom as well as media profiles. Through PTP and synchronous Ethernet, it delivers frequency and time distribution with high accuracy.

Cisco provides two modes of operation for Cisco Nexus 9000 Series Switches. Organizations can deploy Cisco Application Centric Infrastructure (Cisco ACI) or Cisco NX-OS mode.|

Features and benefits

Architectural flexibility

Cisco Nexus 9000 Series Switches support Cisco NX-OS VXLAN EVPN, Cisco Application Centric Infrastructure (Cisco ACI), Cisco IP Fabric for Media, Cisco Nexus Dashboard Data Broker, and IP-routed or Ethernet-switched Layer-2 fabrics using a comprehensive set of unicast and multicast IPv6/IPv4 and Ethernet protocols.

• Purpose-built Cisco NX-OS Software operating system with comprehensive, proven innovations. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability.
• Industry-leading Cisco software-defined networking (SDN) solution with Cisco ACI support. Cisco ACI is a holistic, intent-driven architecture with centralized automation and policy-based application profiles.
• Support for standards-based VXLAN EVPN fabrics, inclusive of hierarchical multisite support (Refer to VXLAN network with MP-BGP EVPN control plane for more information).
• Three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at web scale.
• Comprehensive protocol support for Layer-3 (v4 and v6) unicast and multicast routing protocol suites, including BGP, Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast Sparse Mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).
