# Advanced

The **Advanced** tab lets you specify the error messages sent by the RADIUS server that will not be shown by Parallels Client. This can be useful if an error message is confusing for the user or disrupts user experience.

By default, the "New SMS passcodes sent." is added to the list of ignored messages for DUO Radius. This is done to make authentication via SMS easier for the user. It's not recommended to remove this message from the list of ignored messages.

To add a new message to the list of ignored messages:

1. On the **Advanced** tab, **Tasks > Add** (or click the **\[+]** icon).
2. Type the exact text of the error message you want to be ignored. Messages are not case sensitive. Please note that you have to specify only the text sent by the RADIUS server. For example, if Parallels Client shows an error that reads "Code \[01/00000003] Logon using RADIUS failed. Error: New SMS passcodes sent.", you need to add "New SMS passcodes sent." to the list.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/ras-admin-guide/parallels-ras-21-administrators-guide/connection-and-authentication-settings/multi-factor-authentication/using-radius/advanced.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
