# Ports Management

Ports Management lets you view and control the network ports exposed by an EMQX Tables deployment. You can disable unused ports to reduce unnecessary network exposure.

::: tip Prerequisite

You must have an active EMQX Tables deployment and permission to manage it.

:::

## View Port Status

1. In your EMQX Cloud Console, go to the target EMQX Tables deployment from the **Overview** page or from your project.
2. On the **Deployment Overview** page, find the **Ports Management** button in the **Connection Info** section.
3. Click **Ports Management** to open the dialog.

The dialog displays the protocol, port, and port status. EMQX Tables deployments commonly provide the following ports:

| Protocol | Port | Description |
| --- | --- | --- |
| gRPC | 4001 | gRPC endpoint for EMQX Tables access. |
| MySQL | 4002 | MySQL-compatible endpoint. |
| PostgreSQL | 4003 | PostgreSQL-compatible endpoint. |
| gRPCS | 5001 | TLS-secured gRPC endpoint. |

## Disable a Port

To disable a port, find the corresponding protocol in the **Ports Management** dialog and toggle the switch.

After a port is disabled:

- New clients cannot connect to the EMQX Tables deployment through that protocol and port.
- Existing connections through the disabled port will be dropped; clients must reconnect through an enabled port.

## Re-enable a Port

To re-enable a port, open **Ports Management** and toggle the switch for the corresponding protocol.

Once re-enabled, clients can reconnect through that port.

## Best Practices

- Before disabling a port, verify that no applications, integrations, or external tools are still using it.
- Keep only the ports required by your applications or integrations enabled.
