If you are configuring Cisco ACI datacenter fabric it will sooner or later get to the point that you need to configure multiple objects inside the GUI which will, by using the click-n-click method, take a huge amount of time.

While using POSTMAN to create multiple objects of the same type is the preferred method that everybody is speaking about (because you can generate REST API calls using Python or something similar), the quickest way to do it is using POST of JSON configuration file directly through the GUI.

POSTing JSON config example

As described above, the POST of JSON for some simple yet repetitive configuration is the way to go. Let’s see how it’s done:

Creating multiple BDs inside a tenant in Cisco ACI:

There is always the option to edit a file locally on your computer in notepad++ and then upload it to Cisco device.

With this trick, you can write or edit a file from Flash memory directly from Cisco IOS console. If you need it for whatever reason, maybe to change something in the config file or something else, this is the way to do it.

I was using if for my next article lab where I needed a file on the flash with at least 1600 bytes so I can pull it from neighbouring router with HTTP and check some details in new TCP connection. It was faster to just create the file directly on the router flash and not creating it on my laptop and then transferring it with FTP or TFTP.
