This read-create enumerated value sets the APS switching command: lock(1) locks traffic on its current interface preventing switchover, force(2) forces a switch regardless of interface state, manual(3) requests a switch that can be overridden by a higher-priority condition, and auto(4) lets the system decide based on interface health. Admins set this to manually control or override APS switchover behavior for the protection group. For example, an admin sets this to force(2) to manually force traffic onto the protection interface ahead of planned maintenance on the working interface.
