Home / Packet capture on the internal network core switch
Click the + icon next to the Add Switch field, and select the switch on which you want to enable packet capture. Packet capture and packet analysis are made possible by the multi-step packet capture protocol (PCAP), which makes use of many tools. Packet capture (PCAP) is a tool that helps you to analyze network traffic and troubleshoot network problems. A SPAN session (also known as port mirroring or monitoring) is an association of source ports/VLANs to one or more destination ports.
