● MACsec (Media Access Control Security), standardized by IEEE 802.1AE, provides robust Layer-2 security by encrypting Ethernet frames at line rate, ensuring data confidentiality, integrity, and origin authenticity between connected devices. Implemented in hardware for high performance and low latency, MACsec protects against a wide range of Layer-2 attacks, including eavesdropping, tampering, and replay attacks, and secures critical control-plane protocols.
● IPsec provides data confidentiality, integrity, and authentication between peers at the IP layer. It secures sensitive traffic by establishing secure tunnels between two endpoints, encrypting and authenticating the data flows. IPsec uses protocols such as Internet Key Exchange (IKE) for negotiation and key management, and supports various encryption and authentication algorithms. It protects traffic based on access lists and applies security associations to ensure secure transmission. IPsec tunnels can be configured on Cisco Nexus switches to secure data flows between hosts or gateways, providing network layer encryption without requiring changes to individual applications.
● Flexible forwarding tables that support up to 512,000 shared entries

| Networking |
Cisco N9000 Series Switches support innovative congestion management and flow-control algorithms along with the right latency and telemetry to meet the design requirements of AI/ML fabrics.
● Priority flow control (PFC) is a key capability supported on Cisco N9000 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 data-center-bridging (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 N9000 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 between various flows and apply different queue-management schemes to them based on their network-forwarding requirements in the event of link congestion.
|
| Hardware and software high availability |
● 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 Protocol (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.
● The switches use hot-swappable power-supply units (PSUs) and fans with 1+1 redundancy.
