The Cisco Nexus 9000 Series Switches include both modular and fixed-port switches that are designed to overcome these challenges with a flexible, agile, low-cost, application-centric infrastructure.
The Cisco Nexus 9300 platform consists of fixed-port switches designed for top-of-rack (ToR) and middle-of-row (MoR) deployment in data centers that support enterprise applications, service provider hosting, and cloud computing environments. They are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet switches with up to 2.56 terabits per second (Tbps) of internal bandwidth.
The Cisco Nexus 9000 Series Switches operate in one of two modes – Cisco Application Centric Infrastructure (Cisco ACI) or Cisco NX-OS. In Cisco ACI mode, these switches provide a turnkey, fully automated, policy-based architecture to design and manage data center fabrics. In Cisco NX-OS mode, these switches provide the capability to use foundational layer 2/3 technologies, as well as modern technologies such as VXLAN, with a Border Gateway Protocol‒Ethernet VPN (BGP-EVPN) control plane, segment routing, Multiprotocol Label Switching (MPLS), and automation via NX-APIs.
The Cisco Nexus 9000 Series Switches include the Nexus 9500 Series modular switches and the Nexus 9200/9300 Series fixed switches.
