I am trying to automate tasks in packet trace version 8.2.1, and I am trying to run some commands on a group of routers using a Python script as described by chatGPT. Here is the script:

# Define the list of routers and the command to run
routers = ["R01", "R02", "R03","R04", "R05", "R06", "R07"]
command1 = "config t" + "\n"
command2 = "no ip router eigrp 22" + "\n"
command3 = "do wr" + "\n"

commands = command1 + command2 + command3


Define the username and password for the routers


username = ""
password = ""


Loop through each router and run the command


for router in routers:
    print("Connecting to " + router + "...")
    os.system("vpcs " + router + " sendcmd 'enable\n" + password + "\n" + username + "\n" + password + "\n" + commands + "'")
    print("Command executed on " + router)

I added both Paython and Packet Tracer Folders to the Windows Systenm Variable PATH.

The script output:

C:\Program Files\Python311>C:\Users\Khaled\OneDrive\Documents\Training\Cisco\CCNA\Notes\PS4PT001.PY

I understand that vpcs is the component that helps Packet Tracer to Run Virtual PCs, but it does not seem reachable from outside it for some reason.

I dug on the Internet for a way to enable it or add it to Packet Tracer with no luck.

I tried to ask on the stack network engineers but this kind of question seems not acceptable there because as they said when they closed a similar question: "It is not practical or related to the real production problems".

So, I hope this is the correct place where at last I will find a satisfying answer.

How to get the script to work?
How to use the 'vpcs' with Cisco Packet Tracer?
