UDP port the manager listens on for cluster announcements.

**Signature:**

```typescript
port: number;
```

## Default Value

63000

## Remarks

The socket is opened with address and port reuse, so several processes on one host can listen simultaneously. The port is part of the shared-worker identity: managers using different ports each get their own socket and worker thread. There is no separate send port — this manager only listens.
