    Product Details

    Main benefits of the Cisco Nexus 3400-S switches:

  • ●    With the 12.8-Tbps ASIC, the Cisco Nexus 3408-S series provides 128 ports of 100G or 32 ports of 400G, allowing customers to grow at scale with fewer numbers of switches in their fabric, simplifying management and reducing cost and number of hops.

  • ●    At 400G, the Cisco Nexus 3400-S offers the lowest latency in the industry, of 370ns at high-power efficiency

  • ●    The Cisco Nexus 3400-S offers a programmable pipeline translated to flexible profiles, whether Longest-Prefix-Matching (LPM)-optimized or layer 3 host-optimized. Customers can choose the profile to match their deployment needs.

  • ●    The Cisco Nexus 3400-S supports comprehensive encapsulation and tunneling technologies, Virtual Extensible LAN (VXLAN), VXLAN routing, Multiprotocol Label Switching (MPLS), Generic Protocol Extension (GPE), Geneve, Network Virtualization Using Generic Routing Encapsulation (NVGRE), and more.

  • ●    Cisco Nexus 3400-S switches enable deep network analytics, offering per flow monitoring, queue forensics, and drop-packet forensics to help monitor customer networks.

    The Cisco Nexus 3408-S is a 4-Rack-Unit (RU), 8-slot chassis with the flexibility of 100G or 400G Line-Card Expansion Modules (LEMs) offering 128 ports of 100G or 32 ports of 400G. The Cisco Nexus 3408-S is the industry’s highest port radix in a compact and energy-efficient form factor. The Cisco Nexus 3408-S supports HVAC/DC power inputs with forward airflow direction.

    The Cisco Nexus 3408-S has the following hardware configuration:

  • ●    4RU, 8-slot chassis

  • ●    NXM-X16C LEM with 16 ports of Quad-Small-Form-Factor 28 (QSFP28)

  • ●    NXM-X4D LEM with 4 ports of Quad Small Form-Factor Pluggable – Double Density (QSFP-DD)

  • ●    Beacon LED

  • ●    Status LED

  • ●    Dual-redundant power supplies

  • ●    Redundant (2+1) fans
