Unlike a standard Linux server or an older Catalyst switch, the Nexus 9000 presents a unique challenge: it is a hybrid creature, part Server (CPU) and part high-speed Ferraris (ASICs).
It cannot natively capture data plane traffic (hardware-switched traffic) without specific redirection. 2. Data Plane Capture: SPAN & ERSPAN
If you span a 40Gbps link to a 1Gbps destination port, the buffer fills up, and the switch drops the "copy" packets. You might think the network is dropping traffic, but actually, your monitoring tool is just too slow. nexus 9k packet capture
Ethanalyzer is the go-to tool for troubleshooting traffic destined for or generated by the switch's CPU (Supervisor). It is a CLI-based version of Wireshark built into NX-OS.
When the Nexus 9000 is running in ACI (Application Centric Infrastructure) mode, the story changes dramatically. The switch is now a stateless forwarding engine managed by an APIC controller. Unlike a standard Linux server or an older
