I’ve got a playbook that is triggered by a Netbox Interface change and it’s almost working as expected. When the playbook runs and connected to the Cisco device if it needs to push the block of changes it will push it multiple times which in some cases causes errors. And it will push the commands for every command in the list. For example if there are 3 commands in the task is will send all 3 commands 3 times to the switch. I’m at a loss as to why 
it causes issues with something like “auto qos voip cisco-phone” because it can only be run once so it errors out.
