Question

A network engineer must deploy identical interface descriptions and VLAN assignments across 40 Nexus 9000 switches, where each switch has different values (hostname, management IP, uplink descriptions) pulled from a YAML data file. The engineer wants a maintainable workflow that separates the static configuration structure from the per-device variable data, then renders complete device configurations for each switch. Which approach best meets these requirements?

Accepted Answer

Write a Python script that uses Jinja2 templates for the config structure and loads per-device values from the YAML file to render each configuration

Answer

Create 40 separate static configuration files and paste each into the respective switch using copy-paste through the console

Answer

Use an EEM applet on each switch that triggers on syslog events to generate the interface configuration locally

Answer

Configure NX-API sandbox on each switch and manually build JSON-RPC payloads for every command on every device
