Reason why Optical Interface Attenuation Ratio of a wavelength is set to Blocking on the NMS

The Optical Interface Attenuation Ratio parameter is used to manage the added 40 or 80 wavelengths. You need to first create optical cross-connections for wavelengths on the NMS for the WSM9 board. After the optical cross-connections are created, the default value of this parameter is Blocking for each wavelength.
A wavelength whose Optical Interface Attenuation Ratio is Blocking cannot traverse the WSM9 board because the wavelength attenuation is the maximum. To enable the wavelength to traverse the WSM9 board, set the parameter to another value.
