Product Details

Main benefits of the Cisco Nexus 3400-S switches:

• With the 12.8-Tbps ASIC, the Cisco Nexus 3432D-S provides 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, 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.
