Nornir Service¤

Nornir Service is based on Nornir library - a well adopted open-source tool for automating network devices operations.

Nornir Service Architecture

With each Nornir worker capable of handling multiple devices simultaneously, Nornir Service offers high scalability, allowing efficient management of large device fleets. By optimizing compute resources such as CPU, RAM, and storage, it delivers cost-effective performance.

Additionally, Nornir Service supports various interfaces and libraries for seamless integration. For instance, the cli task can interact with devices via the SSH Command Line Interface (CLI) using popular libraries like Netmiko, Scrapli or NAPALM, providing flexibility for diverse network environments.

Nornir Service Tasks¤

Nornir Service supports a number of tasks to interact with network devices using some of the most popular open source libraries such as Netmiko, NAPALM, Scrapli, Ncclient, Scrapli NETCONF, pygnmi, puresnmp, TextFSM, TTP etc.

Task Description Use Cases
task Run Nornir custom tasks Pure Python per device workflows, do anything you want, it is pure python
cli Executes CLI commands on network devices using libraries like Netmiko, Scrapli or NAPALM. Device diagnostics, retrieving device information.
cfg Manages device configurations, including pushing configurations. Automated configuration management.
test Run test suites against network devices. Network testing, troubleshooting, device compliance, configuration verification.
network A collection of network utilities such as ping and DNS. Check device connectivity, verify and resolve DNS records.
parse Parses command outputs using TextFSM, NAPALM getters or TTP to extract structured data. Data extraction from CLI outputs, automated report generation, configuration validation.
diagram Produce Network L2, L3, OSPF or ISIS routing diagrams in DrawIO or yED formats. Automated network documentation, network validation.
file_copy Copy files to network devices over SCP. Device software upgrades, certificates or license renewal.
runtime_inventory Modify Nornir service runtime inventory. Add, update or remove Nornir hosts at a runtime.
