Cisco Nexus 3400-S Ethernet Switch

SKU: N3K-C3408-S

Cisco Nexus 3400-S overview

The Cisco Nexus® 3400-S is the first 400G capable switch in the Nexus 3000 portfolio with 50 Gbps PAM4 Serial-Deserializers (SerDes), designed for data centers with industry-leading performance-per-watt power efficiency at low latency, offering leading analytics.

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 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.
  • 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 (Figure 1) 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.

  • Layer 3 Switch ensures productivity by providing an efficient, hassle-free connection
  • Supports layer 3 switching for enhanced performance and usability
  • Rack mounting enables you to organize wires & secure cables for professional installation
  • Managed switch provides a reliable foundation for your network
  • 400 Gigabit Ethernet Ethernet technology for a reliable, convenient way of communication and connectivity
  • Supports optical fiber cable to span longer distances and provided high data transmission rates between servers and network components
  • Comes in gray color for better adaption to the space
