Creating a Port without an associated instance using the OpenStack CLI

Port is another building block in OpenStack Neutron. You will not find a way to create a Port using the Horizon dashboard. As we saw earlier in the Associating a Network to an instance using Horizon recipe, a Port is created implicitly as a part of the create instance operation from the dashboard. However, using CLI, some advanced networking configuration can be accomplished. This recipe shows you how to create a Port using OpenStack CLI.

Getting ready

You will need the following information to get started:

  • The login credentials for SSH to a node where the Neutron client packages are installed
  • A shell RC file that initializes the environment variables for CLI
