Hello Naveen
Whenever you want to communicate with a particular entity, it’s always a good idea to check the related API documentation. For EVE-NG, you can take a look at the following link:
Here you should find all you need to interface with the virtual devices in the emulator. In the examples, you will find that they use CURL, a simple Linux CLI tool to communicate through HTTP. You can also find some examples for what you need to use the EVE-NG API at the following lesson, but for this you will need to do some coding yourself:
Finally, you can find some information that people have included on Github about creating Python scripts to communicate with the EVE-NG API at the following link:
These should give you enough information to get started.
I hope this has been helpful!
