All the Switch Requests are for a switch from the primary section to the secondary section. The object csApsActiveline will indicate which section is currently carrying the traffic. Once the switch request clears normally, traffic is maintained on the section to which it was switched by making that section the primary section.

Possible values: workingSection1(1): Working Section 1 is Primary Section workingSection2(2): Working Section 2 is Primary Section none(3) : none.
