Retrieving all Endpoints from ANC policies

The pxGrid client retreives all endpoints from the ANC policies. For more information on the ANC Configuration topic, please see: ANC Configuration

Code Step-Through

The public class ANCGetEndpoints contains the public static void getEndpointsMethod which calls the SampleConfiguration file.

The Sample config object contains the pxGrid connection parameters such as the ISE pxGrid name hostname, identity filename keystore (.jks) filename and the truststore keystore (.jks)filename and we receive the new pxGrid control object. The pxGrid control configuration contains the pxGrid client account, service lookup, and access secret obtained from the ISE pxGrid node

Under //pxGrid ServiceLookup for session service, a service lookup is performed for the ISE node publishing the com.cisco.ise.config.anc service. If there were more the (1) ISE node in the pxGrid, randomization would be performed to find the availble node. This of this is as load balancing to evenly distribute the load.

Under //User first service, we get WebSockets URL from "restBaseUrl" + "/getEndpoints"

Under //pxGrid AccessSecret for the node, we obtain the secret from the ISE pxGrid node

SampleHelper.postObjectAndPrint obtains the ISE pxGrid node, access secret, WebSocket URL, and trust information from the Client Manager.

Main parses the SampleObject Parameters

Under //Account Activate we obtain the pxGridcontrol and wait 60 seconds for the pxGrid client account to be activated, the pxGrid controller version is received, we receive the endpoints from the ANC policies.
