| Arguments | Specify the arguments to be used in the test, e. g. IP addresses that you want to ping. |
If you have created a backup Internet connection on the Failover tab and the automatic heartbeat test defines the state of the connection as disconnected, your LANCOM R&S®Unified Firewall automatically switches to the backup connection with the highest priority available.
The buttons at the bottom right of the editor panel allow you to confirm your changes to the heartbeat test (OK) and to run the connection test manually (Test). You can also reject (Cancel) your changes to the test, close the editor panel and return to the Network Connection editor panel. The specified test is displayed as an entry in the list under Heartbeats on the Failover tab.
