An API that uses REST is often referred as a RESTful API. RESTful APIs use HTTP methods to gather and manipulate data. As there is a defined structure on how HTTP works, HTTP offers a consistent way to interact with APIs from multiple vendors. REST uses different functions to interact with data: HTTP Functions HTTP…

An example of southbound API is if a network operator makes a change to a switches configuration in the management software of the controller. Changes are pushed down from the management software to the network switch using a Southbound API.

Northbound APIs are used to communicate from a network controller to its management software. Cisco DNA Centre has a software graphical user interface that is used to manage the network controller. When a network operator logs into that controller to manage its network, the information is passed from the management software is utilising a Northbound…

Another popular method of communicating with network devices along with the command line interface is the application programming interface, or API. APIs are mechanisms to communicate with application or other software. They can be used to communicate with various components of a network device through software. It is possible to use APIs to configure or…

The most common way to mange a network device is via the command line interface (CLI). One of the biggest flaws with managing a network this way is the possibility of misconfiguration through human error. There are number of pros and cons to a command line interface Pros can be that the command line interface…
