How to turn a mac address into a usable variable

Question

This being my first time posting, I messed some things up. Hopefully I can correct that. By correcting the question and providing more info.

I am needing to use a mac address as a variable. I have tasks that gather information from a client on a network, mac, ip and name. I need to use each one of them as variables, and i can figure out how to use the ip and name, but not the mac.

I have tried to use set_fact, but i am not get it to loop over the clients pulled to be able to use as a variable. Any help would be appreciated.

    - name: Get Vlan 30 Clients
      networks_clients_info:
        meraki_api_key: "{{ MERAKI_KEY }}"
        vlan: 30
        networkId: "{{ store_id.msg[0] }}"
        recentDeviceConnections: Wired
        os: Windows
      register: client_list

    - debug:
        msg: "{{client_list}}"

    - name: Get Client Info
      debug:
        msg: "{{ client_list | 
          community.general.json_query(query) }}"
      vars: 
        query: " meraki_response[*].
           {mac: mac, ip: ip, name: description} "
      register: client_info

    
      

    - name: Get MacAddress
      vars:
        mac_name: client_mac
        mac_value: "{{ client_list | 
         community.general.json_query('meraki_response[].mac') 
          }}"
      set_fact:
        "{{ mac_name }}": "{{ mac_value }}"

    - debug:
        msg: "client_mac = {{ client_mac }}"

    - name: Update a VLAN.
      networks_appliance_vlans:
        meraki_api_key: "{{ MERAKI_KEY }}"
        networkId: "{{ store_id.msg[0] }}"
        state: present
        vlanId: 30
        fixedIpAssignments:
          22:33:44:55:66:77: <-- "{{client_mac}}
            ip: 1.2.3.4 <-- "{{client_ip}}"
            name: Some client name <-- "{{cleint_name}}"

For example, given the data for testing

  meraki_response:
    - {description: d1, ip: 10.1.0.1, mac: aa:bb:cc:11:22:01}
    - {description: d2, ip: 10.1.0.2, mac: aa:bb:cc:11:22:02}
    - {description: d3, ip: 10.1.0.3, mac: aa:bb:cc:11:22:03}

The below expressions

  meraki_query: '[].[mac, {ip: ip, name: description}]'
  result: "{{ dict(meraki_response|
                   community.general.json_query(meraki_query)) }}"

give what you (probably) want

  result:
    aa:bb:cc:11:22:01:
      ip: 10.1.0.1
      name: d1
    aa:bb:cc:11:22:02:
      ip: 10.1.0.2
      name: d2
    aa:bb:cc:11:22:03:
      ip: 10.1.0.3
      name: d3

Example of a complete playbook for testing

- hosts: all

  vars:

    meraki_response:
      - {description: d1, ip: 10.1.0.1, mac: aa:bb:cc:11:22:01}
      - {description: d2, ip: 10.1.0.2, mac: aa:bb:cc:11:22:02}
      - {description: d3, ip: 10.1.0.3, mac: aa:bb:cc:11:22:03}

    meraki_query: '[].[mac, {ip: ip, name: description}]'
    result: "{{ dict(meraki_response|
                     community.general.json_query(meraki_query)) }}"

  tasks:

    - debug:
        var: result
