an be used to generate messages however like python. REST Application Programming Interface is the programmatic Interface to the management Information tree (MIT), a hierarchical tree structure of managed objects. Rest methods like GET, POST, and DELETE are supported through APIs. GET - Nullipotent Method (Does not make any changes even If It is called multiple times) - Read only method POST, DELETE - Idempotent Method (No additional Effect even If It is called more than once with the same input parameters) MANAGEMENT INFORMATION MODEL Hierarchical tree structure of managed objects which can be physical or a logical component of the ACI Fabric that are arranged in parent & child nodes fashion. Every managed object in the Management Information tree are not created by the users, some are automatically created by the ACI Fabric. Application programming Interface exposes full access to the APIC for management, automation, operation, deployment, configuration & a lot more with the REST based approach that Interacts with the APIC which further Interacts with the fabric. There are lot of tools & application available to allow interaction with the Application programming Interface of the controller. We will be using POSTMAN to Interact with APIC APIs (Google Chrome Application to push messages to the controller). Postman is a REST Client that runs as an application inside the Chrome browser and useful application to Interacts with REST APIs of the controller. Format representation of REST commands, some of the calls may not need the payload and we are using either Java Script Object Notation (JSON) or XML for the body or payload of the REST API call: <HTTP verb (GET, POST, PUT, DELETE) > <URI> Downloaded 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 SDN Practical Orientation JSON or XML Body If Required Rest Call to the controller IP address using method Post to login into the APIC POST https://<IP-of-APIC>/api/aaaLogin.jsor "aaaUser" { "attributes" : { "name" : "Username of the APIC", "pwd"
