Command templates overview

Command templates send commands to a set of devices at runtime and evaluate the responses against a defined set of rules. They are typically used as pre- and post-checks around a network procedure—such as a router upgrade or service migration—to verify device state before the change and confirm expected outcomes after it.

A template runs in two phases:

1. It executes each command against the specified devices and collects the responses.
2. Then it evaluates those responses against the rules you have defined, marking each rule as passed or failed.

This makes command templates a structured way to enforce acceptance criteria and catch unexpected device states without manual inspection.

In this section

• Use command templates — Create a template, add commands and rules, test against a live device, and manage templates in the collection view.
• Command reference — Rules, flags, severity levels, variables, and comparison operators.
• Configuration examples — Working examples for common rule and comparison patterns.
