## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_appmesh as appmesh } from 'aws-cdk-lib';

declare const mutualTlsCertificate: appmesh.MutualTlsCertificate;
declare const subjectAlternativeNames: appmesh.SubjectAlternativeNames;
declare const tlsValidationTrust: appmesh.TlsValidationTrust;
const virtualServiceBackendOptions: appmesh.VirtualServiceBackendOptions = {
  tlsClientPolicy: {
    validation: {
      trust: tlsValidationTrust,

      // the properties below are optional
      subjectAlternativeNames: subjectAlternativeNames,
    },

    // the properties below are optional
    enforce: false,
    mutualTlsCertificate: mutualTlsCertificate,
    ports: [123],
  },
};
```
