I am using GNS3 to simulate an environment. I have 4 docker containers which all host Python programs. Three of the devices communicate with each other via the programs (Program 1, Program 2, Program 3).
I am wanting to sniff the traffic between these devices. I have a Python program that sniffs packets on the NIC chip, but do not know how to capture data from the switch. I am wondering if anyone has any resources or experience on sniffing data flowing through a switch in GNS3, specifically in Python. The switch model I am wanting to simulate is Siemens RuggedCom RS900.
