Usage Guidelines

Usage Scenario

Each wave channel corresponds to a wavelength value. After a wavelength is set for an interface, you can run the display wavelength-map command to view the channel corresponding to the wavelength, and then specify the channel in the wavelength-channel command.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display the mappings between wavelengths and channels.

<HUAWEI> display wavelength-map
Info:The command can be run only on tunable optical modules with channel spacings of 50 GHz.
Wave band: C-band
