GlobalLB DNS create and state examples using PowerShell

Problem this snippet solves:

This PowerShell example illustrates how to perform the following GTM tasks using the iControl Cmdlets for PowerShell.

  • GTM Data Center (Create, Enable, Disable)
  • GTM Server (Create)
  • GTM Virtual Server (Create, Enable, Disable)
  • GTM Pool (Create)
  • GTM Wide IP (Create)

How to use this snippet:

The script includes sample usages in the main script logic. You will have to change the input parameters to account for your specific configurations.

  1. Save script as GlobalLBCreate.ps1
  2. Edit main script logic to perform the tasks you are interested in.
  3. $ .\GlobalLBCreate.ps1 bigip_addr bigip_user bigip_pass
