External Interface
This column indicates whether the current interface is an external interface. External interfaces are located in external subnetworks and can be used in connection with this Software Service Station.
If an interface is selected and items on the right of the screen in the menu listing are selectable (not grey) then additional information can be accessed for that device.
In this example "Overview", "Interface update", "Configuration" and "Self-test" are available.
If a device is not correctly configured for the network certain selections may not be available for that device.
Scheme 110
Note. The Interface list does not automatically update as devices are utilized or freed up. The only way to update the list is to select "Overview".
