Interpretation of the Blocking value for the Optical Interface Attenuation Ratio parameter

19

This parameter is used to manage the added 40 or 80 wavelengths. You need to first create optical cross-connections for wavelengths on the WSM9 board. After optical cross-connections are created, the default value of this parameter is Blocking on the NMS 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.
1. When the parameter value is Blocking, click the cell for editing. If you do not set it to another value, a dialog box will be displayed indicating the value range. When you close the dialog box, the attenuation is automatically set to the minimum value.
The value cannot be restored to Blocking.
2. If it is not set, click Query to return to the blocking state.
3. If you have configured the attenuation rate, it cannot be restored to the blocking state. You can delete the optical cross-connection to restore to the blocking state.
Blocking prevents impact of wavelength adding on the line and prevents transient service interruption over existing wavelengths. Set this parameter to Blocking, and allow wavelengths to traverse the board after the optical power is set to a proper value.

Meanings of the values (Monitored and Not Monitored) of the Wavelength Monitor Status parameter for the MAC board
Optical power can be scanned by the MAC board no matter whether Wavelength Monitor Status is set to Monitored or Not Monitored. The parameter setting affects alarms only. For example, if Wavelength Monitor Status is set to Monitored for wavelength 1 but wavelength 1 is not scanned, a CHAN_LOS will be reported. If Wavelength Monitor Status is set to Not Monitored for wavelength 1, no alarm will be reported when wavelength 1 is not scanned.

Difference between the Continue Mode and Burst Mode for the Send Flag parameter of Ethernet test frames
Burst Mode: indicates a burst test. A specific number of test frames are sent at an interval of about 1s. The number of sent test frames can be set in the Frames to Send field. Continue Mode: indicates that test frames are continuously sent, and one frame is sent every about one second.

Description of the Name parameter in a file pool policy of OceanStor 9000
The Name parameter indicates the name of a file pool policy and can contain 3 to 127 characters for OceanStor 9000 V100R001C01 or 1 to 127 characters for OceanStor 9000 V100R001C20/V100R001C30. The characters include only letters, digits, periods (.), hyphens (-), and underscores (_). The parameter must start with a letter and cannot end with a period (.), hyphen (-), or underscore (_).
