This table contains one row for each interface (port or link aggregation) assigned to a logical switch. An interface can only belong to one logical switch at a time. If a logical switch in API mode exists, interfaces cannot be manually added to/deleted from it; instead, interfaces default to the API mode logical switch when not assigned to another Logical Switch. Interfaces can be reassigned from the API mode logical switch to a normal mode logical switch (by adding it to that normal mode logical switch) but not directly reassigned from one normal mode logical switch to another normal mode logical switch.
