In this step, you run additional commands related to the waivers.

To return a collection of CDC waiver objects, enter:
```
get_waivers -type cdc
```
The following CDC waivers are returned:
```
CDC-10#1 CDC-11#1 CDC-11#2 CDC-13#1
```
To filter the list of waivers to only return CDC-13 waivers, enter:
```
get_waivers -filter {ID == CDC-13}
CDC-13#1
```

To report all of the properties on a CDC waiver object, enter:

report_property [lindex [get_waivers -type cdc] end]

The following properties are returned:
