Auto device discovery script for NetBox

Overview

Script for automatically discovering network devices and adding them to NetBox. Supports multiple data sources and various types of devices (router, switch, printer, MFP, Wi-Fi and other).

Dependencies

As root

pip3 install pynetbox toml lxml python-nmap

apt install nmap

Setup

Copy configuration.example.toml to configuration.toml and set the necessary settings.
The program has a modular system. You can enable or disable modules, change the order of their launch. To do this, change the modules list in the configuration.toml (you can comment out a module name to disable it).
Each module has its own configuration, it's stored in a separate TOML table with name of the module. For example, configuration for the module nmap_network_scanner will look like this:

[nmap_network_scanner]
nmap_guess_os = true
nmap_additional_args = "-T4"
snmp_communities = ["public", "jsad084Ji0mapq"]
snmp_retry_count = 2

The following modules are currently implemented:

nmap_network_scanner: scans NetBox prefixes using Nmap and tries to recognize found devices using various techniques;
avaya_ip_office_phones_enumerator: connects to Avaya IP Office IP-PBX via SNMP protocol and receives list of connected devices/VoIP-phones.

Usage

When using nmap_network_scanner module, run the script as a superuser

usage: python3 run.py [-h] [-c] [-v]

optional arguments:
  -h, --help     show this help message and exit
  -c, --cleanup  Remove all auto discovered objects which support tagging from NetBox and exit. This is helpful if you want to start fresh or stop using this script.
  -v, --verbose  Increase verbosity level This overrides the log level in the settings file. Intended for debugging purposes only
