CLI_Parse and loops

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
