Parameters dispersion — Specifies the dispersion compensation.
Values
mode
Syntax mode {automatic | manual}
Context config>port>dwdm>tdcm
Description This command allows users to configure the dispersion algorithm mode used for the port. Manual mode is
used when the user knows the residual dispersion on the link. Automatic mode is used to let the software
determine the optimal dispersion compensation required. Automatic mode should be used during service
commissioning and when the state if the TDCM control is converged, the user can change to manual mode
and configure the dispersion compensation found by the software. Because automatic mode uses a search
algorithm that will sweep the entire range of dispersion specified in the sweep command, it can take up to 10
minutes for the link to come up. In manual mode, the link can come up in 2 minutes or less.
Parameters automatic — Sets to automatic mode.
manual — Sets to manual mode.
