Scan Mode

Short name: Scan Mode

This property specifies what happens to existing connections that conflict with the connections you make in a scan list. For example, if CH1 is already connected to CH2 and the scan list instructs the switch to connect CH1 to CH3, this property specifies what happens to the connection between CH1 and CH2. If the value of this property is NISWITCH_VAL_NONE, the switch takes no action on existing paths. Most switches support only one of the possible values. In such cases, this property serves as an indicator of the device behavior.

NISWITCH_VAL_NONE	No implicit action on connections when scanning.
NISWITCH_VAL_BREAK_BEFORE_MAKE	When scanning, the switch breaks existing connections before making new connections.
NISWITCH_VAL_BREAK_AFTER_MAKE	When scanning, the switch breaks existing connections after making new connections.
