For these set of examples, we will be using a cobra CLI framework for golang, letting us create an individual command for each example as we go along. Read up on the Golang Example Framework for information on how to setup the CLI Framework to get this code to run easily.
Listing vlans is likely the most common thing to do, so it makes a good starting point. This script makes a paginated API call to SoftLayer_Account::getNetworkVlans() and prints out a quick CSV about the servers on your acccount.

This command shows a quick example of how to print out some important details about a specific vlan. A VLAN object has a lot of fields that could be useful aside from what is shown in this command. Hopefully this example is clear enough to get started though.

This example displays how to make an API request that requires parameters be sent in. This will edit a VLANs name property to be whatever you input.
