Actual info from database:
```
mysql> select uuid, local_link_connection from ports;
+--------------------------------------+---------------------------------------------------------+
| uuid | local_link_connection |
+--------------------------------------+---------------------------------------------------------+
| a9c45d04-a3f8-4787-9147-a808c4ecfc81 | {"port_id": "1/1/25", "switch_id": "60:9c:9f:49:a8:84"} |
+--------------------------------------+---------------------------------------------------------+
```
Expected behavior: see non-empty port/switch_id.
Actual behavior: empty local_link_connection field.

Ironicclient supports local_link_connection field on version 1.19 and above.
Try to use option --ironic-api-version 1.19 and then post here about result please.

Looking at the comments in #1 the data is there, but you need to use a newer API version; I also checked the ironicclient version in the Newton UCA against the Newton release notes and we're within range so marking this bug a 'Won't Fix'
