Analyzing Live Traffic Using Wireshark
Wireshark is a well known network protocol analyzer and one of many applications used for network protocol analysis.
Wireshark can interactively browse packet data from a live network or from a previously saved pcap file.
Note: You can download Wireshark from https://www.wireshark.org/
To use Wireshark to decode a previously saved packet flow capture file, export the file from the switch and analyze it with Wireshark.
Note: The path to a NetVisor OS switch pcap file is: /net/<ServerSw_Name>/ONVL/global/flow/<Flow_Name>/<Switch_Name>/pcap
