Data sheet

• Purpose-built Cisco NX-OS Software operating system with comprehensive, proven innovations. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability.
• Industry-leading Cisco Software-Defined Networking (SDN) solution with Cisco ACI support. Cisco ACI is a holistic, intent-driven architecture with centralized automation and policy-based application profiles.
• Support for standards-based VXLAN EVPN fabrics, inclusive of hierarchical multisite support. (Refer to VXLAN network with MP-BGP EVPN control plane design guide for more information)
• Three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at web scale
• Comprehensive protocol support for Layer-3 (v4 and v6) unicast and multicast routing protocol suites, including BGP, Open Shortest Path First (OSPF), Interior System to Interior System (IS-IS), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast Sparse Mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP)
• Segment routing (SR and SRv6) allows the network to forward Multiprotocol Label Switching (MPLS) packets and to engineer traffic without Resource Reservation Protocol (RSVP) Traffic Engineering (TE). It provides a control-plane alternative for increased network scalability and virtualization.
• Cisco IP Fabric for Media helps you migrate from an SDI router to an IP-based infrastructure. In an IP-based infrastructure, a single cable has the capacity to carry multiple bidirectional traffic flows and can support different flow sizes without requiring changes to the physical infrastructure.
• Cisco Nexus Dashboard Data Broker provides customers complete observability into their network and solution(s) that can help them identify and mitigate security threats, realize and remediate performance bottlenecks, adhere to data compliance, and have insight into capacity-planning operations.

• Day-0 automation through Power On Auto Provisioning (POAP), drastically reducing provision time
• Industry-leading integrations for leading DevOps configuration management applications, such as Ansible. Extensive native YANG, and industry-standard OpenConfig model support through RESTCONF/NETCONF/gNMI
• REST API interacting with Cisco NX-OS Software Data Management Engine (DME)
• Model-driven telemetry, which enhances network observability
• Third-party application-hosting using Cisco Application Framework (CAF)

• Flexible forwarding tables that support up to two million shared entries
• Flexible shared ingress and egress of a maximum of 28,000 ACL entries
• IEEE 802.1ae MAC Security (MACsec) capability on all ports, which allows traffic encryption at the physical layer and provides secure server, border leaf, and leaf-to-spine connectivity

• Priority Flow Control (PFC) is a key capability supported on Cisco Nexus 9000 Series Switches that prevents Ethernet frame drops by signaling, controlling, and managing Ethernet flows along a path by sending pause frames to appropriate senders.
• The platform also supports Explicit Congestion Notification (ECN), which provides end-to-end notification per IP flow by marking packets that experienced congestion, without dropping traffic. The platform is capable of tracking ECN statistics, including the number of marked packets that have experienced congestion.
• The platform offers lossless transport for Remote Direct Memory Access (RDMA) over converged Ethernet (RoCE) with support of dData- cCenter bBridging (DCB) protocols:
• Enhanced Transmission Selection (ETS) reserves bandwidth per priority class in network contention situations.
• Data Center Bridging Exchange Protocol (DCBX) can discover and exchange priority and bandwidth information with endpoints.
• Weighted Random Early Detection (WRED) is a congestion-avoidance technique that allows Cisco Nexus 9000 Series Switches to detect and react to congestion in the network by marking flows that could cause congestion.
• The platform offers Cisco’s innovative intelligent buffer management, which offers the capability to distinguish mice and elephant flows and apply different queue-management schemes to them based on their network forwarding requirements in the event of link congestion.
• Approximate Fair Dropping (AFD) with Elephant Trap (ETRAP). By using ETRAP, AFD distinguishes long-lived elephant flows from short-lived mice flows. ETRAP measures the byte counts of incoming flows and compares this against the user-defined ETRAP threshold. After a flow crosses the threshold, it becomes an elephant flow.
• Dynamic Packet Prioritization (DPP) provides the capability of separating mice flows and elephant flows into two different queues so that buffer space can be allocated to them independently.

• Virtual port-channel (vPC) technology provides Layer-2 multipathing through the elimination of Spanning Tree Protocol (STP).
• Capability to link fabrics in a VXLAN environment, eliminating the need for peer-to-peer vPC. The 128-way Equal-Cost MultiPath (ECMP) routing enables the use of Layer-3 fat-tree designs. This feature helps organizations prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
• Software-maintenance upgrades (SMUs) contain fixes for specific defects. They provide a quick resolution of critical issues.
• In-service software upgrades (ISSUs) allow upgrades of device software while the switch continues to forward traffic. ISSUs reduce or eliminate the downtime typically caused by software upgrades.
• The switches use hot-swappable power-supply units (PSUs) with 1+1 redundancy and fans with N+1 redundancy.
