The Cisco Nexus 3016 Switch, part of the Unified Fabric family, provides wire-rate Layer 2 and Layer 3 switching, and delivers 40 Gigabit Ethernet bandwidth.

Features and Capabilities

  • Ultra-low latency:
    • Helps you implement high-performance infrastructures for high-frequency trading workloads
    • You can increase application performance by switching at 40 Gigabit Ethernet speeds
  • Wire-rate Layer 2 and 3 switching on all ports:
    • Layer 2 and 3 switching of up to 1.2 Tbps and more than 950 million packets per second (mpps) in a compact 1RU form-factor switch
  • Purpose-built on Cisco NX-OS operating system with comprehensive, proven innovations:
    • Modular OS built for resiliency
    • Full Layer 3 routing protocol suites, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing Information Protocol Version 2 (RIPv2)
  • Integration with Cisco Data Center Network Manager (DCNM) and XML management tools
