Network automation using various python modules in Python3

Network-Automation-Scripts using Python3

Libraries: Pyeapi, Netmiko, Napalm, Telnetlib, Restconf, Nxapi, Nornir, Netconf

This repository hold various automation scripts I've written over the years. My goal has been to use this as a repository for knowledge retention as well knowlege sharing. I plan to continue to grow this respository as long as I'm still doing stuff in the network automation space.

This has been a iterative learning process for me and I will be archiving or deleting scripts that no longer have value.

Nornir - TestDrive

• Cisco IOS - GNS3 lab - nornir/using_netmiko_plugin
• Arista Ceos lab - nornir/using_napalm_plugin
• Testing newer version of Nornir, not backwards compatible with version 1.x

Netconf

• Tested on Cisco DevNet Gear
• Still learning not much here
• netconf_ex1.py
• netconf_get_conf.py

Nxapi

• Found this api documentation to be lacking
• Script examples I found were rigid and not very flexible
• Created a script to allow user to enter any commands (config/show) w/o having to rewrite the script.
  • nxapi_script_ex1.py

Restconf

• Still learning this api
• restconf_ex1.py

Pyeapi - Python client for Arista eAPI

• Cleaning up directory archived some scripts and created interactive script folder
• Posted configs and validation scripts for ceos demo
• Posted configs and validation from demo
• hidden host config file, needs to be located in ~/.eapi.conf
• created two sample scripts

Netmiko testing

• Created a script to go out and automatically determine the device_type for a host_list or seedfile.
  • NetworkDiscovery/host_file_and_script/auto_detect_script.py
• sample script to connect to juniper device
  • juniper_script1.py
  • juniper_conf_from_file.py
• scp
  • file transfers to veos devices hosted using vagrant
  • file transfers to multiple devices using containerized eos or ceos
• Network-Automation-Scripts_Python3/netmiko/NetworkDiscovery/host_file_and_script/
  • ios_discovery_script.py
  • host_file.txt
• Added 3 examples of how to use jinja templates with netmiko
• conf_bgp_r4_r5_using_class_obj. - uses class object to populate template
• conf_bgp_r4_r5_using_dict.py - uses dictionaries to populate template
• conf_bgp_yaml_jinja2.py - uses yaml files to populate a jinja2 template
• Created new script that provide you a sandbox to say how many devices, what devices, and what to configure on each
  • ssh_sandbox.py
• Created a very basic ssh script useful for discovery + updated with error handling
• Created script that can handle multiple device with multiple unique configuration files
• Added multiprocessing to speed up
  • netmiko_multi_dev_cfg.py
• Added multiprocessing Pools to scripts to speed them up
  • netmiko_script5.py
  • netmiko_show_cmds.py
  • netmiko speed comparison between serial and multi-processing pools
• netmiko_script#.py
• capture output of scripts

Napalm for eos

• /config_scripts/conf_merge
• /config_scripts
• Tested with ipython(python3.6) -> EOS_lab_Napalm_test_results
• napalm_eos_script1.py

Napalm for cisco ios

• napalm discovery script and post script
  • discovery_ios_svc_now.py
  • post_svc_now_rest_api.py
• created a config_scripts directory added new script
  • script_config_ios.py
• added new get_facts and get config script to directory
• Testing with python3 napalm_base and napalm_ios
• In my gns3 environment I'm using the following code
  • C7200-ADVENTERPRISEK9-M, Version 15.2(4)S7
  • IOS provides access to a subset of napalms features
  • EOS has been a more feature rich testbed with napalm

Telnetlib module

• Use python3 telnetlib module
• capture output of scripts
