# Suppressing showmount Command Output on NFSv3 Clients

By default, when an NFSv3 host runs the `showmount` command, VAST Cluster returns a complete list of all NFSv3 exports on the cluster, including those to which the host does not have access (based on the view policies).

To prevent this, you can configure the cluster to suppress complete listing of all NFSv3 exports for all clients. This setting is made at the cluster level:

- In VAST Web UI, use the Enable suppressed showmount option in cluster's general settings (Settings -> Cluster -> General).
- In VAST CLI, run the `cluster modify` command with the `--enable-suppressed-showmount` or `--disable-suppressed-showmount` option specified.

When suppression is enabled, by default any client running a `showmount` command gets the following response:

```plaintext
'/' everyone(rw)
```

You can further suppress the `'/' everyone(rw)` line in the response as follows:

- In VAST Web UI, use the Hide the "/" export option in cluster's general settings (Settings -> Cluster -> General).
- In VAST CLI, run the `cluster modify` command with the `--enable-showmount-hide-slash` or `--disable-showmount-hide-slash` option specified.
