List VLAN number and based on the last number create new VLAN

[czopereq76]

Hi All,

I am trying to add VLAN according to the last number available on the switch. In my case right now the last VLAN number is 100 so I would like to add next one with number 101. However running my playbook it looks like iteration over VLAN list is not in order and playbook created VLAN 15 instead of 101.

I would like to run iteration in order from 1 to 100 and then create VLAN 101. Does any one know how to achieve this?

- name: VLAN NUMBER
set_fact:
vlan_index: {{ sh_vlan_output.stdout[0].vlans.keys() | map('int') |
list | max + 1 }}

This should do what you are looking for.
