Chapter 5. Review OpenStack Networking router ports

Virtual routers in OpenStack Networking use ports to interconnect with subnets. You can review the state of these ports to determine whether they’re connecting as expected.

5.1. View current port status

This procedure lists all the ports attached to a particular router, then demonstrates how to retrieve a port’s state (DOWN or ACTIVE).

1. View all the ports attached to the router named r1: 

#  neutron router-port-list r1

Example result: 

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

2. View the details of each port by running this command against its ID (the value in the left column). The result includes the port’s status, indicated in the following example as having an ACTIVE state: 

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