Description

This article describes how to add a model device to FortiManager using the FortiManager API.

 

Scope

FortiManager.

 

Solution

Use the following API call to create a Model Devices under the Device Manager database.

 

{
    "method": "exec",
    "params": [
        {
            "data": {
                "adom": "<ADOM>",
                "device": {
                    "device action": "add_model",
                    "name": "<Model_Device_Name>",
                    "mgmt_mode": "fmg",
                    "os_ver": "7.0",
                    "mr": 4,
                    "os_type": "fos",
                    "sn": "<Serial Number of FortiGate>"
                },
                "flags": [
                    "none"
                ]
            },
            "url": "/dvm/cmd/add/device"
        }
    ],
    "session": "<SESSION_ID>",
    "id": 2
}


Here, 'os_ver' is the version and 'mr' is the patch; in this case, the version of the model device will be v7.4.

Optional Flags can be used:

Flag

Action

linked_to_model

Automatically Link to Real Device

need_reset

ZTP Factory Reset

sdwan_management

Managmenet through SDWAN Manager (v7.6 and higher)

override_management_intf

Enforce Device Configuration


Add model HA cluster:

Under the 'device' part of the API call, use the following options:

"ha_mode": "AP",
"ha_group_name": "ha_cluster",
"ha_group_id": 1,
"ha_slave": [
    {
        "idx": 0,
        "sn": "<Primary Serial>",
        "psk": "",
        "name": "<Model Device Name>",
        "role": "master",
        "prio": 1
    },
    {
        "sn": "<Secondary Serial>",
        "psk": "",
        "idx": 1,
        "name": "<Device Name for Secondary>",
        "role": "slave",
        "prio": 0
    }
]


  • ha-mode: 'AA' for Active-Active and 'AP' for Active Passive.

  • name: For primary the name should match the Model Device Name.

  • idx: Index - start from 0.

  • psk: Set only if using Pre-Shared Key option instead of Serial Number.

  • prio: Prority, Primary should have higher value.


Add Model Device Using Blueprint:

Under the 'device' part of the API call, use the following option:

"device blueprint": "<Blueprint Name>",


Note: Make sure the Blueprint exists in FortiManager. See Using device blueprints for model devices.


Verify device creation:

{
    "method": "get",
    "params": [
        {
            "url": "/dvmdb/adom/<ADOM_NAME>/device"
        }
    ],
    "session": "<SESSION_ID>",
    "id": 3
}


Troubleshooting:

The following commands can be used on the FortiManager CLI to debug the API Calls:


diagnose debug service httpd 255
diagnose debug service main 255
diagnose debug enable
