# Troubleshooting

#### RADIUS Data

If you click on the **Export Radius Data** button, you download an excel file in which you can see which devices are registered in the RADIUS data.

#### RADIUS Server

You can test on the RADIUS server if the device is not only on the list but also on the server.

Also, you can, for example, investigate a list of devices that are on the server:

#### Switch Configuration

If you have problems with configuring the switch, you can look for more information [here](https://docs.xeox.com/port-based-nac/kfxwencCzErupyXTXVc93F/switch-settings/kAeSGzXy8BbKUyGSg2U2pe).

#### Synchronizing Problem on RADIUS Server

In most cases, if the device is listed but not on the server, there is likely a synchronization issue.

In this case you can check if the heartbeat is up-to-date. It should usually only be a few minutes old. If it's older, the server is most certainly not synchronized.
