Introduction to Python Network Libraries (Netmiko, NAPALM, Nornir, and More)
summary
Overview of practical use: Netmiko provides device CLI access over SSH telnet serial, with bindings to ntc_templates/TextFSM and Genie to return structured data; author notes Netmiko became noticeably slow in 2020 but is being optimized. NAPALM exposes uniform getters and ACID-like config operations (replace/merge/commit/discard/rollback) by creating synthetic candidate configs for platforms that lack them and supports five core platforms. Nornir is a Python framework handling inventory and concurrency with default 20 workers and plugins for Netmiko and NAPALM.
