Home Networking Network Switches Cisco N3K-C34180YC 48x25G & 6x100G Data Center Switch

Cisco N3K-C34180YC 48x25G & 6x100G Data Center Switch

Brand:
Cisco

The Cisco N3K-C34180YC is a high-density Nexus 3400 Series switch delivering 48 flexible 10/25G server-facing ports and 6 high-speed 100G uplinks. Designed for cloud-scale infrastructure, virtualization, and modern data centers, it combines low-latency performance with programmable networking capabilities.

OVERVIEW

  • The Cisco N3K-C34180YC is a high-performance data center Ethernet switch engineered for modern enterprise, cloud, and hyperscale environments that require scalable 25G server connectivity and high-bandwidth 100G aggregation. Featuring 48 flexible 10/25G SFP ports and 6 dedicated 100G QSFP28 uplinks, it supports evolving network architectures without requiring major infrastructure redesign.
  • As part of the Nexus 3400 Series, this model combines programmable switching capabilities, wire-speed Layer 2 and Layer 3 performance, and support for VXLAN/EVPN-based network virtualization. Compared to lower-density access switches, it provides greater server consolidation, higher uplink capacity, and enhanced automation readiness. These advantages make it particularly attractive for organizations investing in hybrid cloud strategies, data center modernization, and long-term infrastructure scalability.
