    Posted 27 days ago


    I need to update a static host List in Clearpass with API but I receive an error 400 : The request sent by the client was syntactically incorrect.

    I don't find the correct value to send. 

    With Update some fields of a static host list by name (, the payload in pyhton is :

    payload = {
        "host_entries": {
            "A0-B0-C0-D0-00-01": "device1",
            "A0-B0-C0-D0-00-02": "device2",
            "A0-B0-C0-D0-00-03": "device3"
        "host_format": "list",
        "host_type": "MACAddress"

    But in the description : :[{"host_address": "", "host_address_desc" : "My host address description."}, {..} ..]. I have try few thins without success. Someone know the correct format ?

    What works many times, is to retrieve an object (static hostlist in your case) via the API and get/use to format from there.

      "id": 3003,
      "name": "TestSHL",
      "description": "Test",
      "host_format": "list",
      "host_type": "MACAddress",
      "host_entries": [
          "host_address": "00-00-11-11-22-22",
          "host_address_desc": "Test1"
          "host_address": "11-22-33-44-55-66",
          "host_address_desc": "Test2"

    That would be the format/structure to build in python. You can check the format with print(json.dumps(payload)), and make sure the {} and [] and "label": are all in the right place.

    Note that Static Host lists are most times not the best way of achieving a result. Using the Endpoint Database or Guest Device database (with attributes) is the more mainable approach.
