dcpOpsSwitchMode

Indicates the configured protection switching mode
of the Optical Protection Switch.
          
auto(1) -
    Non-revertive mode. Traffic is carried on the line
    that becomes active first when the system starts.
          
    If the active line fails, traffic switches to the
    other available line.
          
    When the failed line recovers, traffic remains on
    the currently active line until a forced switch is
    performed or the active line fails.
          
    This behavior applies symmetrically to both Line A
    and Line B.
          
revertiveA(2) -
    Revertive mode with Line A as the preferred line.
    Traffic switches to Line B upon failure of Line A
    and automatically reverts to Line A after recovery.
          
revertiveB(3) -
    Revertive mode with Line B as the preferred line.
    Traffic switches to Line A upon failure of Line B
    and automatically reverts to Line B after recovery.
          
forcedA(4) -
    Forced mode. Line A is selected regardless of
    failure conditions.
          
forcedB(5) -
    Forced mode. Line B is selected regardless of
    failure conditions.
