# OpenThread CLI Reference

The OpenThread CLI exposes configuration and management APIs via a command line interface. Use the CLI to play with OpenThread, which can also be used with additional application code. The OpenThread test scripts use the CLI to execute test cases.

## Separator and escaping characters

The whitespace character (`' '`) is used to delimit the command name and the different arguments, together with tab (`'\t'`) and new line characters (`'\r'`, `'\n'`).

Some arguments might require to accept whitespaces on them. For those cases the backslash character (`'\'`) can be used to escape separators or the backslash itself.

Example:

```bash
> networkname Test\ Network
Done
> networkname
Test Network
Done
>
```

### dns config

Get the default query config used by DNS client.

The config includes

- Server IPv6 address and port
- Response timeout in msec (wait time to rx response)
- Maximum tx attempts before reporting failure
- Boolean flag to indicate whether the server can resolve the query recursively or not.
- Service resolution mode which specifies which records to query. Possible options are:
  - `srv` : Query for SRV record only.
  - `txt` : Query for TXT record only.
  - `srv_txt` : Query for both SRV and TXT records in the same message.
  - `srv_txt_sep`: Query in parallel for SRV and TXT using separate messages.
  - `srv_txt_opt`: Query for TXT/SRV together first, if it fails then query separately.
- Whether to allow/disallow NAT64 address translation during address resolution (requires `OPENTHREAD_CONFIG_DNS_CLIENT_NAT64_ENABLE`)
- Transport protocol UDP or TCP (requires `OPENTHREAD_CONFIG_DNS_CLIENT_OVER_TCP_ENABLE`)

```bash
> dns config
Server: [fd00:0:0:0:0:0:0:1]:1234
ResponseTimeout: 5000 ms
MaxTxAttempts: 2
RecursionDesired: no
ServiceMode: srv_txt_opt
Nat64Mode: allow
TransportProtocol: udp
Done
>
```

### dns config \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\] \[service mode]

Set the default query config.

Service mode specifies which records to query. Possible options are:

- `def` : Use default option.
- `srv` : Query for SRV record only.
- `txt` : Query for TXT record only.
- `srv_txt` : Query for both SRV and TXT records in the same message.
- `srv_txt_sep`: Query in parallel for SRV and TXT using separate messages.
- `srv_txt_opt`: Query for TXT/SRV together first, if it fails then query separately.

To set protocol effectively to tcp `OPENTHREAD_CONFIG_DNS_CLIENT_OVER_TCP_ENABLE` is required.

```bash
> dns config fd00::1 1234 5000 2 0 srv_txt_sep tcp
Done

> dns config
Server: [fd00:0:0:0:0:0:0:1]:1234
ResponseTimeout: 5000 ms
MaxTxAttempts: 2
RecursionDesired: no
ServiceMode: srv_txt_sep
Nat64Mode: allow
TransportProtocol: tcp
Done
```

We can leave some of the fields as unspecified (or use value zero). The unspecified fields are replaced by the corresponding OT config option definitions `OPENTHREAD_CONFIG_DNS_CLIENT_DEFAULT_{}` to form the default query config.

```bash
> dns config fd00::2
Done

> dns config
Server: [fd00:0:0:0:0:0:0:2]:53
ResponseTimeout: 3000 ms
MaxTxAttempts: 3
RecursionDesired: yes
Done
```

### dns resolve \<hostname\> \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\] \[transport protocol\]

Send DNS Query to obtain IPv6 address for given hostname.

The parameters after `hostname` are optional. Any unspecified (or zero) value for these optional parameters is replaced by the value from the current default config (`dns config`).

To use tcp, `OPENTHREAD_CONFIG_DNS_CLIENT_OVER_TCP_ENABLE` is required.

```bash
> dns resolve ipv6.google.com
> DNS response for ipv6.google.com - 2a00:1450:401b:801:0:0:0:200e TTL: 300
```

The DNS server IP can be an IPv4 address, which will be synthesized to an IPv6 address using the preferred NAT64 prefix from the network data.

> Note: The command will return `InvalidState` when the DNS server IP is an IPv4 address but the preferred NAT64 prefix is unavailable.

```bash
> dns resolve example.com 8.8.8.8
Synthesized IPv6 DNS server address: fdde:ad00:beef:2:0:0:808:808
DNS response for example.com. - fd4c:9574:3720:2:0:0:5db8:d822 TTL:20456
Done
```

### dns resolve4 \<hostname\> \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\]

Send DNS query to obtain IPv4 address for a given hostname and provide the NAT64 synthesized IPv6 addresses for the IPv4 addresses from the query response.

Requires `OPENTHREAD_CONFIG_DNS_CLIENT_NAT64_ENABLE`.

The parameters after `hostname` are optional. Any unspecified (or zero) value for these optional parameters is replaced by the value from the current default config (`dns config`).

This command requires a NAT64 prefix to be configured and present in Thread Network Data.

For example, if a NAT64 prefix of `2001:db8:122:344::/96` is used within the Thread mesh, the outputted IPv6 address corresponds to an IPv4 address of `142.250.191.78` for the `ipv4.google.com` host:

```bash
> dns resolve4 ipv4.google.com
> DNS response for ipv4.google.com - 2001:db8:122:344:0:0:8efa:bf4e TTL: 20456
```

### dns browse \<service-name\> \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\]

Send a browse (service instance enumeration) DNS query to get the list of services for given service-name.

The parameters after `service-name` are optional. Any unspecified (or zero) value for these optional parameters is replaced by the value from the current default config (`dns config`).

```bash
> dns browse _service._udp.example.com
DNS browse response for _service._udp.example.com.
inst1
inst2
inst3
Done
```

The detailed service info (port number, weight, host name, TXT data, host addresses) is outputted only when provided by server/resolver in the browse response (in additional Data Section). This is a SHOULD and not a MUST requirement, and servers/resolvers are not required to provide this.

The recommended behavior, which is supported by the OpenThread DNS-SD resolver, is to only provide the additional data when there is a single instance in the response. However, users should assume that the browse response may only contain the list of matching service instances and not any detail service info. To resolve a service instance, users can use the `dns service` or `dns servicehost` commands.

```bash
> dns browse _service._udp.example.com
DNS browse response for _service._udp.example.com.
inst1
    Port:1234, Priority:1, Weight:2, TTL:7200
    Host:host.example.com.
    HostAddress:fd00:0:0:0:0:0:0:abcd TTL:7200
    TXT:[a=6531, b=6c12] TTL:7300
Done
```

```bash
> dns browse _airplay._tcp.default.service.arpa
DNS browse response for _airplay._tcp.default.service.arpa.
Gabe's Mac mini
    Port:7000, Priority:0, Weight:0, TTL:10
    Host:Gabes-Mac-mini.default.service.arpa.
    HostAddress:fd97:739d:386a:1:1c2e:d83c:fcbe:9cf4 TTL:10
Done
```

> Note: The DNS server IP can be an IPv4 address, which will be synthesized to an IPv6 address using the preferred NAT64 prefix from the network data. The command will return `InvalidState` when the DNS server IP is an IPv4 address but the preferred NAT64 prefix is unavailable. When testing DNS-SD discovery proxy, the zone is not `local` and instead should be `default.service.arpa`.

### dns service \<service-instance-label\> \<service-name\> \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\]

Send a service instance resolution DNS query for a given service instance. Service instance label is provided first, followed by the service name (note that service instance label can contain dot '.' character).

The parameters after `service-name` are optional. Any unspecified (or zero) value for these optional parameters is replaced by the value from the current default config (`dns config`).

> Note: The DNS server IP can be an IPv4 address, which will be synthesized to an IPv6 address using the preferred NAT64 prefix from the network data. The command will return `InvalidState` when the DNS server IP is an IPv4 address but the preferred NAT64 prefix is unavailable.

### dns servicehost \<service-instance-label\> \<service-name\> \[DNS server IP\] \[DNS server port\] \[response timeout (ms)\] \[max tx attempts\] \[recursion desired (boolean)\]
