# Restricting a token generator to certain virtual server IDs

Virtual server IDs provide more configuration flexibility in cases where you need to identify your server differently when connecting to a partner in one connection for multiple environments or in multiple connections where the partner also supports multiple federation IDs.

## About this task

When you multiplex one connection for multiple environments, you can enforce integration requirements by restricting a token generator to certain virtual server IDs on the **Virtual Server IDs** tab. By default, no restriction is imposed. For more information, see [Multiple virtual server IDs](../introduction_to_pingfederate/virtual_server_id.html).

|   | If you are editing a currently mapped token generator instance, you can toggle the **Restrict Virtual Server IDs** setting. You can also change the allowed virtual server IDs. |

## Steps

1. On the **Token Generator Mapping & User Lookup** tab, click **Map New Token Generator Instance** to open the **Token Generator Mapping & User Lookup** configuration window.

2. Click the **Virtual Server IDs** tab.

   Select the **Restrict Virtual Server IDs** checkbox.

   Select one or more virtual server IDs that you want to allow for this token generator.
