Deleting an ANC Policy

The pxGrid client deletes an ANC policy by policy name. In this example, the pxGrid client deletes the Test4 ANC policy. For more information on the ANC Configuration topic, please see: ANC Configuration

Code Step-Through

We create the public class ANCDeletePolicy where the string name for the desired ANC policy will be deleted.

The private static void apply method calls SampleConfigObject string name and ip address. 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" + "/deletePolicyName"

Under //pxGrid AccessSecret for the node, we obtain the secret from the ISE pxGrid node and the policy to be deleted based on the policy id.

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, the desired ANC policy to be deleted.
