# changeTargetGroupConfiguration

Available in VPC

Change target group settings.

## Syntax

The `changeTargetGroupConfiguration` syntax is as follows:

```
./ncloud vloadbalancer changeTargetGroupConfiguration \
    --targetGroupNo <target-group-no> \
    [--useStickySession <true|false>] | [--useProxyProtocol <true|false>] \
    [--algorithmTypeCode <RR|SIPHS|LC|MH>] \
    [--regionCode <KR|SGN|JPN>] \
    [--output <json|xml>]
```

## Options

This section describes the options available when running `changeTargetGroupConfiguration`.

### Required options

The following options are required for `changeTargetGroupConfiguration`.

| Options | Type | Required | Description |
| --- | --- | --- | --- |
| `--targetGroupNo` | String | Required | Target group number - See [getTargetGroupList](/docs/en/cli-vloadbalancer-targetgroup-gettargetgrouplist). |
| `--useStickySession` | Boolean | Conditional | Whether to use per-session access - `true` \| `false` - `true`: Enabled. - `false`: Disabled. - Can be set if the target group's protocol type is `TCP`, `UDP`, `HTTP`, or `HTTPS`. - When changing target group settings, at least one among `useStickySession`, `useProxyProtocol`, or `algorithmTypeCode` must be entered. |
| `--useProxyProtocol` | Boolean | Conditional | Proxy protocol usage - `true` \| `false` - `true`: Enabled. - `false`: Disabled. - Can be set if the target group’s protocol type is `PROXY_TCP`. - When changing the target group settings, at least one among `useStickySession`, `useProxyProtocol`, or `algorithmTypeCode` must be entered. |
| `--algorithmTypeCode` | String | Conditional | Load balancing algorithm type - `RR` \| `SIPHS` \| `LC` \| `MH` - `RR`: Round robin. - `SIPHS`: Source IP hash. - `LC`: Least connection. - `MH`: Maglev hash. - Available values are limited depending on the target group’s protocol type. - `HTTP`, `HTTPS`, `PROXY_TCP` protocols: `RR` \| `SIPHS` \| `LC` - `TCP`, `UDP` protocols: `RR` \| `MH` - When changing target group settings, at least one among `useStickySession`, `useProxyProtocol`, or `algorithmTypeCode` must be entered. |

### Common options

For information about the options common to all `vloadbalancer` subcommands, see [Load Balancer (VPC) options](/docs/en/cli-vloadbalancer#%EC%98%B5%EC%85%98).

## Examples

If the request to change the target group settings is successful, the configuration information for the updated target group is returned.

### Command

The command example is as follows:

```
./ncloud vloadbalancer changeTargetGroupConfiguration \
    --targetGroupNo 55667788 \
    --useStickySession true \
    --algorithmTypeCode RR \
    --regionCode KR \
    --output json
```
