Show configuration parser i.e. shconfparser is a Python library, whcih parser Network configurations. This library examines the config and breaks it into a set of parent and clild relationships.

shconfparser is a vendor independent library where you can parse the following formats:

  • Tree structure i.e. show running
  • Table structure i.e. show ip interface
  • Data i.e. show version

Tree Structure

show run to tree structure

Table Structure

show cdp neighbour to table structure


How to use shconfparser?

  • How to split show commands from a file
>>> from shconfparser.parser import Parser
>>> from os import path
>>> file_path = path.abspath('data/shcommands.txt')
>>> p = Parser()
>>> data = # read file content
>>> data = p.split(data) # split each show commands and it's data
>>> data.keys()
odict_keys(['running', 'version', 'cdp_neighbors', 'ip_interface_brief']) # keys
  • How to convert running config to Tree structure
>>> data['running'] = p.parse_tree(data['running']) # translating show running data to tree format
>>> p.dump(data['running'], indent=4) # running data in tree format

shconfparser supports both trains of python 2.7+ and 3.1+, the OS should not matter.

Installation and Downloads

The best way to get shconfparser is with setuptools or pip. If you already have setuptools, you can install as usual:

python -m pip install shconfparser

Otherwise download it from PyPi, extract it and run the script

python install

If you're Interested in the source, you can always pull from the github repo:

  • From github git clone


  • Question: I want to use shconfparser with Python3, is that safe?
    Answer: As long as you're using python 3.3 or higher, it's safe. I tested every release against python 3.1+, however python 3.1 and 3.2 not running in continuous integration test.

  • Question: I want to use shconfparser with Python2, is that safe?
    Answer: As long as you're using python 2.7 or higher, it's safe. I tested against python 2.7.
