The video demonstrates how to perform packet capture on Cisco Nexus 1000V with SPAN and ERSPAN. SPAN allows traffic on the same ESXi host as the packet capture machine to be captured, while ERSPAN allows the packet capture machine to be on a different ESXi from a source or even multiple layer 3 hops away. We uses FTP as a sample application in this lab.
Note:
- For SPAN, destination port must be on the same host (linecard) as the source.
- ERSPAN transports captured packet across a network using GRE encapsulation tagged with a ERSPAN ID.
