Severity

Warning - although this alert indicates a serious issue that should be addressed, it does not pose an immediate risk of data loss, security breach, or service interruption. If the problem is not corrected, however, more severe problems could occur.

Cause

This alert is triggered when an authority server is unable to connect to the configured RADIUS server. The alert provides the hostname or IP address of the affected RADIUS server.

Possible effects

Before you begin

You should have an understanding of the RADIUS networking protocol.

Recommended solution

To resolve this alert:

  • Go to Settings > Security > RADIUS and validate the RADIUS server settings
  • Verify that the RADIUS server is powered on
  • Verify that the RADIUS server is reachable from the command line of the authority server
  • Confirm that the RADIUS server responds on the configured port using telnet and ping
