How it works...

We run this new playbook against all nodes within the core and wan group, and we use the ios_facts module to collect the information from the managed IOS devices. In this recipe, we use the debug module to print out the information that was collected from the ios_facts module. The following is a subset of the information that was discovered:

ok: [core01 -> localhost] => {
  "Ansible_facts": {
    "net_all_ipv4_addresses": [
      "172.20.1.20",
< ---------- Snippet ------------ >
      "10.1.100.1"
    ],
    "net_hostname": "core01",
    "net_interfaces": {
 < ---------- Snippet ------------ >
      "Vlan10": {
        "bandwidth": 1000000,
        "description": null,
        "duplex": null,
        "ipv4": [
          {
            "address": "10.1.10.1",
            "subnet": "24"
          }
        ],
        "lineprotocol": "up",
        "macaddress": "aabb.cc80.e000",
        "mediatype": null,
        "mtu": 1500,
        "operstatus": "up",
        "type": "Ethernet SVI"
      },
 
    },
    "net_iostype": "IOS",
    "net_serialnum": "67109088",
    "net_system": "ios",
    "net_version": "15.1",
  }
 < ------------ Snippet ------------ >
 }

From the preceding output, we can see some of the main facts that the ios_facts module has captured from the devices, including the following:

• net_all_ipv4_addresses: This list data structure contains all the IPv4 addresses that are configured on all the interfaces on the IOS device.
• net_interfaces: This dictionary data structure captures the status of all of the interfaces on this device and their operational state, as well as other important information, such as a description and their operational state.
• net_serialnum: This captures the serial number of the device.
• net_version: This captures the IOS version running on this device.
