This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support enhanced diagnostics from the CLI. The show commands described later in this document can be used to view the instantaneous values for various modulation parameters like Signal-To-Noise Ratio, Residual Inter Symbol Interference, PAM4 Level Transition Parameters, etc. that such optics support.

Note:. EOS 4.21.0F and subsequent releases may require manual updates to frequency or channel and grid spacing in
