### Commissioner name and ID flags
All CHIP Tool commands can be used together with the following
commissioner-related flags:
- `--commissioner-name`
- `--commissioner-nodeid`
These flags let you control which fabric and node ID are used for the CHIP Tool
when interacting with devices. They are especially useful in scenarios where you
are working with more than one fabric, but you can also use them with a single
CHIP Tool node identity.
#### `--commissioner-name` flag
This flag lets you control which fabric is used by selecting a specific fabric
commissioner.
As per the CHIP Tool implementation, the commissioners are required to have the
following names: `alpha` for the first one, `beta` for the second one, `gamma`
for the third one, `4` for the fourth one, `5` for the fifth one, and so on.
If you don't use this flag, the CHIP Tool assumes that the command is meant for
the `alpha` commissioner and hence for the fabric associated with this
commissioner.
**Example of commands:**
```
$ ./chip-tool any subscribe-by-id '0x0028,0x0028,0x0101,0x0028,0x0028,0x0028' '5,6,0,1,2,4' 100 1000 1 '0,0,1,0,0,0' --keepSubscriptions true
$ ./chip-tool any subscribe-by-id '0x0028,0x0028,0x0101,0x0028,0x0028,0x0028' '5,6,0,1,2,4' 100 1000 2 '0,0,1,0,0,0' --keepSubscriptions true --commissioner-name beta
$ ./chip-tool any subscribe-by-id '0x0028,0x0028,0x0101,0x0028,0x0028,0x0028' '5,6,0,1,2,4' 100 1000 3 '0,0,1,0,0,0' --keepSubscriptions true --commissioner-name gamma
```
#### `--commissioner-nodeid` flag
This flag lets you select the node ID to use on the fabric specified with the
`--commissioner-name` flag.
If you don't use this flag, the CHIP Tool assumes that the command is sent with
the ID value that the CHIP Tool has in storage. If there's none, the CHIP Tool
sends the command with the default fallback node ID `112233`.
> **Note:** If the device has been already commissioned with a specific
> `--commissioner-nodeid`, you must always provide the `--commissioner-nodeid`
> flag with the CHIP Tool commands or update the Access Control List (ACL) on
> the device. Otherwise, the default fallback node ID `112233` is used and the
> communication will fail.
**Example of commands:**
```
$ ./chip-tool pairing code-thread 1 hex:000030000150208562618342348532605109bd31cda6908667addca8789211addac0102c4a9 34970112332 --commissioner-name alpha --commissioner-nodeid 999999

### Pairing
The `pairing` command supports different means regarding Matter device
commissioning procedure.
The `pairing` command supports different methods for Matter device commissioning
procedure. The recommended methods are the following:
Thread and Wi-Fi commissioning use cases are described in the
[Using the CHIP Tool for Matter device testing](#using-chip-tool-for-matter-device-testing)
section.
- `code-thread` - For Thread commissioning.
- `code-wifi` - For Wi-Fi commissioning.
- `code` - For commissioning the device when it is already present in an IP
network.
Alternatively, you can also use the following methods described in the
[Using CHIP Tool for Matter device testing](#using-chip-tool-for-matter-device-testing)
section:
To list all `pairing` sub-commands, run the following command:
- `ble-thread` - For Thread commissioning; described under
[Commissioning into a Thread network over Bluetooth LE](#commissioning-into-a-thread-network-over-bluetooth-le).
- `ble-wifi` - For Wi-Fi commissioning; described under
[Commissioning into a Wi-Fi network over Bluetooth LE](#commissioning-into-a-wi-fi-network-over-bluetooth-le)
- `onnetwork` - For commissioning the device when it is already present in an
IP network; described under
[Commissioning with setup PIN code](#commissioning-with-setup-pin-code)
To list all `pairing` sub-commands and commissioning methods, run the following
command:
```
$ ./chip-tool pairing
```
**Example of commands:**
The following command commissions the Thread device with the node ID `1` to the
Matter fabric. The `hex:...` parameter is the operational dataset that contains
information about the Thread network to which the device is going to be
commissioned. The onboarding dataset payload `34970112332` (short manual pairing
code) is used to discover and commission the device.
```
$ ./chip-tool pairing code-thread 1 hex:000030000150208562618342348532605109bd31cda6908667addca8789211addac0102c4a9 34970112332
```
The following command commissions the Wi-Fi device with the node ID `1` to the
Matter fabric The SSID `wifi_test` and the password `admin123` is the required
information about the Wi-Fi network to which the device is going to be
commissioned. The onboarding dataset payload `34970112332` (short manual pairing
code) is used to discover and commission the device.
```
$ ./chip-tool pairing code-wifi 1 wifi_test admin123 34970112332
```
The following command commissions the device with the node ID `1` to the Matter
fabric. The onboarding dataset payload `MT:8IXS142C00KA0648G00` (QR code
payload) is used to discover and commission the device.
```
$ ./chip-tool pairing code 1 MT:8IXS142C00KA0648G00
```
#### Attestation-related flags
The `pairing` commissioning command can be run with several flags that allow you
to modify attestation-related settings:
- `--paa-trust-store-path` - Use to provide the path to the directory that
contains the information about Product Attestation Authority (PAA)
certificates. The path can be absolute or relative to the current working
directory. With this flag, the CHIP Tool looks for the PAA certificate that
matches the PAI and the DAC certificates programmed on the device. Without
this flag, the CHIP Tool uses the built-in test PAA certificate.
- `--cd-trust-store-path` - Use to provide the path to the directory
containing the key that is used to validate the device's Certification
Declaration. The path can be absolute or relative to the current working
directory. With this flag, the CHIP tool looks for additional public keys,
in addition to the well-known built-in public keys (built-in public keys
`src/credentials/attestation_verifier/DefaultDeviceAttestationVerifier.cpp`),
to be used to validate Certification Declaration signatures.
* `--only-allow-trusted-cd-keys` - Use to only allow the keys from
`--cd-trust-store-path` and not the built-in test key. If the flag is not
provided or it is provided with the value `false`, untrusted CD verifying
keys are allowed. If it is provided with the value `true`
(`--only-allow-trusted-cd-keys true`), test keys are disallowed and CD
signed with the test key will not be accepted.
* `--bypass-attestation-verifier` - Use to bypass the attestation verifier. If
the flag is not provided or it is provided with the value `false`, the
attestation verifier is not bypassed. If it is provided with the value
`true` (`--bypass-attestation-verifier true`), the commissioning will
continue in case of the attestation verification failure. The failure can be
caused by errors in Certification Declaration, PAA or PAI certificates, or
in the Device Attestation Certificate. This option can be helpful if you
want to quickly commission a device with PAI and DAC certificates based on
an unknown PAA and/or with a Certification Declaration signed by an unknown
key.
