When an external interface to the Control Station fails because of device failure or loss of connectivity to the IP network, the Control Station may fail over to another host. However, the operator needs to know that the interface has failed and which devices may have been affected.
External network cable failure to a control station shows a scenario where an external interface on the Control Station has failed (2 in the figure).
In this case, the following notifications are generated:
Notifications: Host (Control Station) Unresponsive
Root Cause: Interface Down
Impact: Host (Control Station) Unresponsive
