# `clone_interface` Command

## Name

`clone_interface`

## Synopsis

```
clone_interface [<nic>]...
```

## Description

Adds the specified NICs to the `cloned_interfaces` variable.  This is a
friendly wrapper for `cloned_interfaces="${cloned_interfaces} $1"` in essence.
This command can be safely mixed with any raw variable setting of
`cloned_interfaces`, as long as care is taken in the raw variable setting
code not to overwrite the variable, but instead append to it.
