I am a bit new to ansible, I am ok at making playbooks on static devices. What I would like to do is make a playbook that is sort of universal. I would like to add a vlan to a cisco switch then automatically add it to all the trunk ports. First what I am trying is to add vlans to all the trunk ports. I am not sure if I am doing this correctly. I want to loop all the l2\_interfaces that are set to trunk and add the vlans on the switch to them as allowed vlans. I think this script is working off of a predetermined list of vlans and ports.

hosts: all  
connection: network\_cli  
gather\_facts: no  
vars:  
ansible\_network\_os: ios

tasks:

- name: Get config for IOS devices  
ios\_facts:  
gather\_subset:

- ‘!all’

- ‘!min’  
gather\_network\_resources:

- ‘l2\_interfaces’

- name: Configure L2 Trunks  
ios\_l2\_interfaces:  
name: “{{ item.name }}”  
mode: “{{ item.mode }}”  
trunk\_allowed\_vlans: “{{ vlans | map(attribute=‘vlan\_id’) | join(‘,’) }}”  
state: present  
loop: “{{ l2\_interfaces[ansible\_net\_hostname] | selectattr(‘mode’,‘equalto’,‘trunk’) | list}}”
