I have written this play to run over a Cisco Router- then create a list of interfaces and the idea is to only apply a config to an interface based on the value or not of the descrption.

The play works fine up until the last point.

- block:
- name: write config to interface  
with\_indexed\_items: " {{ my\_list }} "  
ios\_config:  
lines: description CHANGED  
parents: GigabitEthernet{{ item.1 }}  
provider: “{{ cli }}”  
match: none  
**when: “’ description ANSIBLE’ in output.results[{{ item.0 }}].stdout\_lines”**

It just says **conditional check failed**

**skipping: [CSR-02] =\> (item=(1, u'GigabitEthernet2')) =\> { "changed": false, "item": [1, "GigabitEthernet2"], "skip\_reason": "Conditional check failed", "skipped": true**

All I want to do is for the interface that has a description of Ansible to perform a config change.

**What am I doing wrong?**

Don't use curly brackets in when:, they are implied.  
If you do you can get all kind of strange behavior.

when: "' description ANSIBLE' in output.results[item.0].stdout\_lines"

Thanks, tried that but it still skips the conditional check.

After checking the variable output I see that the  
output.results[item.0].stdout\_lines  
contains a list of lists so you need to use

output.results[item.0].stdout\_lines.0
