The industrial revolution modernized the techniques used to manufacture goods, going from hand production methods to mechanized manufacturing. This movement from manual to automated operations changed human productivity, allowing people to free themselves from repetitive tasks that could be more easily accomplished by a machine. The associated decrease in costs, increase in speed and increased quality allowed for more work to be done for less money in less time, yielding a higher quality product.

Programmability promises to offer the same outcome for networks as the industrial revolution did for goods. The inevitable move toward automation in the IT industry has provided people and businesses a faster way to achieve their desired goals, a more cost-effective way to rapidly provision infrastructure in a timely fashion according to demand, and yielded more consistency in the configured results.

ACI is able to take advantage of all of these benefits by completely exposing all of the native functionality in programmable ways, using common tools and languages to provide network engineers, developers and even novices an approachable path toward automation. Though ACME is just getting started with true DevOps in their IT organization, they realize that these benefits will allow them to keep up with the pace of business. Given the comprehensiveness of the programmability features available on ACI, everyone can benefit.

ACME's network engineering and design teams can benefit from the quick time to provision large configurations, and the consistency provided by the ability to automate all of the moving parts. Their operations teams can utilize the plethora of information contained within the APIC to streamline their processes, gather better metrics and correlate events more accurately, yielding faster time to resolution and higher customer satisfaction. The goals for network programmability are clear, however the methods by which these goals may be realized have been more difficult to grasp.

Traditional networking devices provide output that is meant for visual consumption by people, and configurations are driven using text input that is simpler for a person to type, however these goals stand in contrast to an automation-driven approach. Machines are able to more easily process data that is provided in some structured form. Structured data that may not be visually appealing can be rapidly parsed, and also can easily represent the full detail that a comprehensive object-oriented configuration model may represent.

ACI uses an advanced object model that represents network configuration with application-based semantics which can be consumed and posted against using a well documented REST API.

In addition to providing this interface into the object model, ACI also provides a number of access methods to read and manipulate this data, at a variety of levels that will cater to the level of comfort the user has with programming, all of which use open standards and open source. While a comprehensive overview of the Object Model is outside of this book, from a programmability perspective it is important to note that every aspect of ACI functionality is encompassed within the object model.

This includes internal fabric networking, external networking, virtualization integration, compute integration, and all other facets of the product. This data is stored within the Management Information Tree, with every piece of the model represented as a programmatic object with properties, identity, and consistency rules that are enforced.

This ensures that the configured state of the model will never get out of hand with stale nodes or entries, and every aspect can be inspected, manipulated, and made to cater for the user's needs. APIC is very flexible in terms of how it can accept configuration and provide administrative and operable states, as well as extending that configuration into subordinate components.

There are two primary categories of interfaces that facilitate these functions: the northbound REST API and the southbound programmatic interfaces. The northbound REST API is responsible for accepting configuration, as well as providing access to management functions for the controller.I am trying to create multiple subnets in one bridge domain using postman for ACI automation. I want to know if there is a document specific to the automation mentioned above.

Can someone help me with this please.

Once you have this collected, you can change the EPG name with the corresponding variables that you defined in spreadsheet.

In this example, I'm going to create multiple EPG that we defined from the previous spreadsheet to the tenant 'rsantoso' within the 'rsantoso-ap' application profile. If you haven't already add this. Otherwise you'll find the response with no authentication. In the Collection Runner, you'll find the Iteration is based on the number of rows that you enter.

If this request is run without login, you'll find the authentication error. You need to login first so that you have a valid token for your subsequent requests. In the response of login script you would see token and refresh timeout by default seconds. If the session is established and remains idle for seconds, then you may have to post the login script again.

With this you can run multiple sequential script with one go, eg. I read in ACI documentation that once you get the auth token from the login request, then you should use it in next requests. If I create a script in python to make both requests, do I have to send the token in the second request as an Authorization request header?

In postman, it maintains the session like browser. So when we post login payload, a session is created which lasts for seconds default token refresh timeout. So any subsequent requests are allowed bydefault since they are part of the same session.

In case of firing APIs with python, to avoid overhead of sending token through header of subsequent request, you should use request. Buy or Renew.Introduction II. Postman Collection Runner 1.
