# SourceZixiPush

Configuration for Zixi Push.

No port option is exposed: MediaConnect assigns the Zixi Push ingest port itself —
public sources are served on 2088, VPC sources are auto-assigned a port in 2090–2099.
The service rejects any user-supplied port value, so the L2 surface doesn't accept one.

Extends: SourceZixiPush
Extends: SourceBase

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/flow-source-configuration.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/flow-source-configuration.ts#L298)

## Example

```ts
declare const stack: Stack;

const flow = new Flow(stack, 'MyFlow', {
  source: SourceConfiguration.zixiPush({
    flowSourceName: 'zixi-source',
    maxLatency: Duration.millis(2000),
    network: NetworkConfiguration.publicNetwork('203.0.113.0/24'),
  }),
});
```
