Hi Guys,
I want to add a condition to stop execution of playbook if “vlan not found”. I am attaching my playbook tasks below:

  • name: check vlan availability
    ios_command:
    commands:

  • show vlan id {{ vlan1 }}
    register: precheck

  • name: check voice_vlan availability
    ios_command:
    commands:

  • show vlan id {{ vlan2 }}
    register: precheck_voice_vlan

  • name: L2 Vlan1 Availability Check
    debug:
    msg: “Vlan not present in the switch”
    when: “‘not found’ in precheck”

  • name: L2 Vlan2 Availability Check
    debug:
    msg: “Vlan not present in the switch”
    when: “‘not found’ in precheck_voice_vlan”

You should check “end_play”:

  • block:

  • name: Closing tasks
    …

  • meta: end_play
    when: vlan_not_present_condition

This will end the playbook completely.

You might also look at changed_when or failed_when. Here are some examples.
