 ### Description for `action`-related fields
 
 For the Net Emulation and Bandwidth fault types, you can further configure the `action` related parameters according to the following description.
 
-- Net Emulation type: `delay`, `loss`, `duplicated`, `corrupt`

 For occasional events such as `reorder`, `loss`, `duplicate`, and `corrupt`, the `correlation` is more complicated. For specific model description, refer to [NetemCLG](http://web.archive.org/web/20200120162102/http://netgroup.uniroma2.it/twiki/bin/view.cgi/Main/NetemCLG).

+Setting `action` to `rate` means simulating bandwidth rate fault. This action is similar to [bandwidth/rate](#bandwidth) below, however, **the key distinction is that this action can combine with other `netem` actions listed above**. However, if you require more control over the bandwidth simulation such as limiting the buffer size, check the [bandwidth](#bandwidth) action.
