Configlets

Type	What it does	Approval
config	Enters configuration mode, applies the commands and saves the configuration (or commits on Junos, IOS-XR, PAN-OS, VyOS…).	Yes: it creates a change request.
exec	Runs query commands (show, display…) and shows each device’s output.	No: it is immediate.

Variables

Commands are Jinja2 templates. You can use device data and your own variables, which are asked for when it runs:

vlan {{ vlan_id }}
 name {{ vlan_name }}
{% if device.group == "Core" %}
spanning-tree vlan {{ vlan_id }} priority 4096
{% endif %}
! applied on {{ device.name }} ({{ device.host }})

Device variables: device.name, device.host, device.model, device.os_version, device.serial, device.location, device.device_type, device.group.

Run

1. Click Run on the configlet’s card: a side panel opens.
2. Fill in the detected variables: there is one field for each, and the command preview updates as you type.
3. Choose the compatible devices: one by one, all, none or a whole group.
4. For config: click Create change request and wait for approval. For exec: you see the output right away.
