    [--output <json|xml>]
```

| Options | Type | Required | Description |
| --- | --- | --- | --- |
| `--nasVolumeInstanceNo` | String | Required | NAS volume instance number - Access control settings can only be configured for NAS volume instances where the volume allocation protocol type is NFS. - See [getNasVolumeInstanceList](/docs/en/cli-vnas-volume-getnasvolumeinstancelist). |
| `--accessControlRuleList` | List | Required | Access control rule list - For each rule, enter {field='value'} pairs enclosed in quotes and separated by commas. - `serverInstanceNo` (required): Server instance number to add to access control.

```
./ncloud vnas addNasVolumeAccessControl \
    --nasVolumeInstanceNo 10234567 \
    --accessControlRuleList "serverInstanceNo='34567890', writeAccess='true'" \
    --regionCode KR \
    --output json
```
