F5OS API - not able to create vlan

Hi all,

GET request: https://10.10.10.10/api/data/openconfig-vlan:vlans

Gives me JSON payload as here:

{
    "openconfig-vlan:vlans": {
        "vlan": [
            {
                "vlan-id": 405,
                "config": {
                    "vlan-id": 405,
                    "name": "v405_10.10.20.0_m29"
                },
                "members": {
                    "member": [
                        {
                            "state": {
                                "interface": "Production_trunk"
                            }
                        }
                    ]
                }
            }
        ]
    }
}

When I try to add new vlan or at least send the same contect with "PATCH https://10.10.10.10/api/data/openconfig-vlan:vlans" I get an error:

400 BAD request

{
    "ietf-restconf:errors": {
        "error": [
            {
                "error-type": "application",
                "error-tag": "malformed-message",
                "error-path": "/openconfig-vlan:vlans",
                "error-message": "object is not writable: /oc-vlan:vlans/oc-vlan:vlan[oc-vlan:vlan-id='405']/oc-vlan:members/oc-vlan:member"
            }
        ]
    }
}

Why so and how the PATCH works here, from documentation it works more like PUT, but well OK.

Am I supposed to send all vlans in case I need to just add or remove 1 vlan - so I always have to send all of them in the PATCH?

Thanks,

Zdenek
