Track dead servers only

When RADIUS tracking is enabled with the radius-server tracking enable command, tracking is done for all the RADIUS servers that are configured. When the radius-server tracking dead-server-only command is executed, only nonfunctional (dead) servers are tracked.

If there is no response, a RADIUS server is considered nonfunctional with one of the following reasons:

  • Route does not exist from switch to server.

  • Invalid or No key configured.

  • Network issues.

Switch detects that the server is nonfunctional when server-timeout occurs during dot1x/macauth/webauth authentication with RADIUS server.
