Assuming you have all macs in a list:

  • name: process mac addresses into a list
    set_fact:
    result: “{{result | default() | union([ ‘Interface’ + idx|string + ': ’ + item]) }}”
    loop: “{{macs}}”
    loop_control:
    index_var: idx

  • name: set fact
    set_fact:
    final: “{{result|join(‘\n’)}}”

You could use a template like this:

{% for iface in ansible_interfaces | difference(['lo','eth0']) | sort %}
{{ iface }}: {{ hostvars[inventory_hostname]['ansible_' ~
iface]['macaddress'] }}
{% endfor %}

This will yield:

eth1: 08:00:27:b3:59:d0
eth2: 08:00:27:87:1b:de
eth3: 08:00:27:9b:80:85
eth4: 08:00:27:90:ad:eb
