CLI_Parse and loops

[colli...@gmail.com]

Hello everyone.   I am having some issues with using the information from cli_parser output. '''

    - name: Create po_ch variable

      ansible.netcommon.cli_parse:

        command: "show etherchannel summary"

        parser:

          name: ansible.netcommon.pyats

        set_fact: po_ch

      tags: debug

    - name: Create a list of interfaces that are PortChannel Memebers

      set_fact: 

        exclude_ints: "{{ item.value.port_channel.port_channel_member_intfs }}"

      loop: "{{ ansible_facts.po_ch.interfaces|dict2items }}"

      tags: debug

    

    - name: Debug new set fact

      debug:

        msg: "{{ exclude_ints }}"

      tags: debug

```

And here is the output

So it loops and the exclude_ints variable only has the last 2 interfaces when there are more than one portchannel on the device. How can I merge these to a list and use that in a when statement further down in the play.  

Any help would be apprciated.

Thank you!

Either concatenate the lists in the loop

- set_fact:
exclude_ints: "{{ exclude_ints|default([]) +
[item.value.port_channel.port_channel_member_intfs]
}}"
loop: "{{ po_ch.interfaces|dict2items }}"

or use json_query

- set_fact:
exclude_ints: "{{ po_ch.interfaces|json_query(query) }}"
vars:
query: '*.port_channel.port_channel_member_intfs'

In both cases the result will be a list of lists

exclude_ints:
- - GigabitEthernet1/0/37
- GigabitEthernet1/0/38
- - GigabitEthernet1/1/2
- GigabitEthernet1/1/4

In both cases it's possible to flatten the list if needed. For example

- set_fact:
exclude_ints: "{{ po_ch.interfaces|json_query(query)|
flatten }}"
vars:
query: '*.port_channel.port_channel_member_intfs'

gives

exclude_ints:
- GigabitEthernet1/0/37
- GigabitEthernet1/0/38
- GigabitEthernet1/1/2
- GigabitEthernet1/1/4

Thanks again Vladimir.  json_query was the answer again.  Need to read up on that some more to understand the syntax.  These examples are extremely helpful.

Again thank you for taking the time
