In the event of link congestion. ● Approximate Fair Dropping (AFD) with Elephant Trap (ETRAP). AFD distinguishes long-lived elephant flows from short-lived mice flows by using ETRAP. ETRAP measures the byte counts of incoming flows and compares them 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. Hardware and software high availability ● Virtual Port-Channel (vPC) technology provides Layer-2 multipathing through the elimination of Spanning Tree Protocol (STP). ● Can-do fabric link in the VXLAN environment, eliminating the need for peer-to-peer VPC ● The 64-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 a specific defect and 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) and fans with N+1 redundancy. Cisco Nexus Dashboard ● Cisco Nexus Dashboard is a platform that transforms data-center and cloud-network operations through simplicity, automation, and analytics. Cisco Nexus Dashboard Fabric Controller (NDFC), Cisco Nexus Dashboard Insights (NDI), Cisco Nexus Dashboard Orchestrator (NDO), and Cisco Nexus Dashboard Data Broker (NDDB) are integrated as services into Cisco Nexus Dashboard. ● Cisco Nexus Dashboard is included with all Cisco Nexus 9000 switch tiered licenses. Cisco Nexus Dashboard Fabric Controller requires a Cisco Data Center Networking (DCN) Essentials license, Cisco Nexus Dashboard Orchestrator requires a DCN Advantage license, and Cisco Nexus Dashboard Insights requires a DCN Premier or a DCN Day 2 Ops add-on license.

The 48 downlink ports on the 93180YC-FX3 are capable of supporting 1-, 10-, or 25-Gbps Ethernet, offering deployment flexibility and investment protection. The 6 uplink ports can be configured as 40 or 100-Gbps Ethernet, offering flexible migration options. The Cisco Nexus 93180YC-FX3 switch supports standard PTP telecom profiles with SyncE and PTP boundary clock functionality for telco data-center edge environments. Figure
