Complete the following steps to lists all of the ports that attach to a particular router and to retrieve the current state of a port (DOWN or ACTIVE):

  1. To view all the ports that attach to the router named r1, run the following command:

    Example result: 

    +--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+
| id                                   | name | mac_address       | fixed_ips                                                                            |

  2. To view the details of each port, run the following command. Include the port ID of the port that you want to view. The result includes the port status, indicated in the following example as having an ACTIVE state: 

    # openstack port show b58d26f0-cc03-43c1-ab23-ccdb1018252a
