If set, this value indicates the overload bit should be set and then cleared after sysUpTime exceeds this value. It lets an admin schedule the overload bit to clear itself automatically at a future sysUpTime rather than requiring a second manual SET, useful for a timed maintenance drain where the router should rejoin normal transit routing once the window is expected to be over. For example, setting this to a sysUpTime value 30 minutes in the future automatically clears the router's self-declared overload state after that half hour without any further admin action.
