Basic Get ANC Endpoints¶
This sample gets all endpoints with a Cisco Adaptive Network Control (ANC) policy applied to them.
Prerequisites¶
The samples configuration step has been completed (see Samples Configuration).
The DXL fabric to which the client will connect has been bridged to Cisco pxGrid.
The Python client has been authorized to perform
DXL Cisco pxGrid Queries
(see Authorize Client to Use Cisco pxGrid via DXL).
Running¶
To run this sample execute the
sample/basic/basic_anc_get_endpoints_example.py
script as
follows:
python sample/basic/basic_anc_get_endpoints_example.py
If information can be retrieved successfully for the endpoint, the output should appear similar to the following:
{ "endpoints": [ { "macAddress": "00:11:22:33:44:55", "policyName": "ANC_Shut" } ] }
Details¶
The majority of the sample code is shown below:
with DxlClient(config) as dxl_client: # Connect to the fabric dxl_client.connect() logger.info("Connected to DXL fabric.") # Create client wrapper client = CiscoPxGridClient(dxl_client) try: # Invoke 'get endpoints' resp_dict = client.anc.get_endpoints() # Print out the response (convert dictionary to JSON for pretty # printing) print("Response:\n{0}".format( MessageUtils.dict_to_json(resp_dict, pretty_print=True))) except Exception as ex: print(str(ex))
Once a connection is established to the DXL fabric, a
dxlciscopxgridclient.client.CiscoPxGridClient
instance is created which
will be used to communicate with Cisco pxGrid.
Next, the dxlciscopxgridclient.client.AncClientCategory.get_endpoints()
method.
The final step is to display the contents of the returned dictionary (dict
)
which contains the results of the attempt to retrieve the endpoints.
