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.

• 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

• Getting used to xmlns is a challenge and can be frustrating. Took me a while to find the proper xmlns to config a loopback
• Wrote a script to find out where that xmlns is in the server capabilities dump
  • netconf_svr_capability.py
  • netconf_svr_capability_ouput.txt
• Documentation around netconf is not intuitive from my point of view
• This will be a trial and error process.
• Script to config loopback interface
  • netconf_config_device.py - configured a loopback on devnet router
  • netconf_config_device_output.text - results
• Script to do config backups.
  • netconf_iosxe_cfg_bkup.py - rewrite of netconf_config_bkup.py
  • netconf_config_bkup.py - goes out pulls running config and places it in config_bkup/ directory
  • netconf_config_output.txt - the results of the script
• First time using netconf
  • netconf_ex1.py
  • netconf_get_conf.py

• Minor update to the to make output from commands more readable
  • added : print(json.dumps(response, indent=2, sort_keys=True))
  • added nxapi_script02.py and nxapi_script02_output.txt for comparison to original script
• 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

• Created two scripts one to create an interface and the other to delete it
  • create_intf.py
  • delete_intf.py
  • script_output.txt

• pyeapi_w_out_conf.py - using pyeapi without config file
• 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

• Got a request today to help someone write a script. Created folder and will keep the scripts in there.
  • script_requests/req_config_script_07292020.py
• Haven't messed around with Netmiko in quite a while decided to play around and try and update an old script to have both (show/conf) functionality.
• It's painfully slow as I haven't added any features such as MP to it to speed it up, but it was working with the devnet CSRs.
• Basically the script will ask the user if this is going to be a configuration or show commands script. Depending on the answer the script will do one or the other.
  • test_stuff/interactive_script.py
  • test_stuff/interactive_script_output.txt
• NetworkDiscovery/host_file_and_script/ has the most pragmatic scripts for doing network discovery (ie..scripts that run show commands and captures the results and saves them to files)
• Netmiko scripts for running show commands can be found in the NetworkDiscovery folder
  • show_commands.py - easiest for every day troubleshooting and operations and lab work
• Python3.7 works with the scripts as written. Python3.8 is not yet ready.
• Reorganized some config scripts into config_scripts folder
  • Scripts are self explanatory
• 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_enable_mode.py - if enable pw is required
  • ios_discovery_script.py - if username/password priv level 15
  • 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

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

• 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

• Added script that works with devices that require enable password
• Use python3 telnetlib module
• capture output of scripts

• script to find duplicate ips
  • findingDupIPs.py
• simple way to iterate through cli commands when running a script
  • loop_thru_cli_cmds.py
  • loop_thru_cli_cmds_output.txt
