title: Saltstack check before using pillar
body: <p>Good afternoon, if you can help, I will be grateful, I use saltstack with napalm to automate the cisco configuration in the <code>/srv/salt/interfaces/</code> folder there are 2 files <code>vlan.sls</code> and <code>vlan.jinja</code>, I successfully execute this command from this files when I run, but how to check not applying this config on hardware? Because by default, it immediately applies the change and applies it in <code>startup -config</code>. Thank you very much!!</p>
