In the previous post, we have seen how to leverage the TEXTFSM parser with netmiko. In this post, we will see how to install and parse data with Netmiko Genie plugin into a formatted data structure that we can easily export to a datasheet.
List of available GENIE PARSERS.
Step1:- Install pyats and netmiko
You can execute
pip install genie
#but genie is also available as a part of pyats framework.
#you could also execute
pip install pyats[full]
Step2:- Once genie is installed. Modify your netmiko script to use “use_genie=True” instead of “use_textfsm=True”
