Network Automation¶
Practical guides for engineers who want to stop typing the same commands on a hundred devices. Each article is hands-on, with working examples you can adapt in a lab first. The tools build on each other: start with scripting the CLI, then move to declarative and model-driven approaches as your needs grow.
Articles¶
- Netmiko for Network Engineers: connect over SSH, run show commands, parse with TextFSM or Genie, push config, run across many devices concurrently and handle errors.
- NAPALM: Getters, Config Replace and Rollback: vendor-neutral getters, merge versus replace, compare_config, rollback, and when to choose it over Netmiko.
- Ansible for Cisco IOS XE: inventory, cisco.ios modules, resource modules, idempotency, Vault, plus backup and VLAN playbooks.
- Terraform for Network Engineers: infrastructure as code for networks, providers, state, the plan and apply workflow and a small VPC example.
- Git and CI/CD for Network Configs: repository layout, pre-commit checks, Batfish or pyATS validation, deploy pipelines, approvals and rollback.
- YANG, NETCONF, RESTCONF and gNMI Walkthrough: find a model, read and change config with ncclient and curl, and stream telemetry with gnmic.
- pyATS and Genie: Snapshot, Diff and Test the Network: Testbed YAML, parsing and learning, before/after snapshots with pyats learn and diff, AEtest checks, and running from CI.
