    dol och


    [no] dol och:location_id [ admin-status status | bandwidth bandwidth | central-frequency frequency | custom1 string | custom2 string | custom3 string | ol-id string ]


    This command sets parameters for the specified DOL optical channel (OCH) on a ROADM module. If the optical channel does not exist, the optical channel is created. An optical channel is a user-traffic-bearing channel (wavelength) that is cross-connected in the ROADM node as part of an overall optical service.

    Note: Optical channels on line ports in a ROADM module must be manually created using this command. Optical channels on client ports in a ROADM module are automatically created when you create an optical cross-connect, and should not be manually created or deleted.





    Default Value


    The optical channel identifier

    The identifier consists of the chassis, module, and port locations, followed by a channel identifier.

    The format of the OCH identifier is as follows:

    • och:chassis/slot/0/Cn/channel for the client ports (1<=n<=max_degrees)
    • och:chassis/slot/0/L1/channel for the line port


    • channel is an alphanumeric string up to 32 characters long


    admin-status status

    The administrative status of the optical channel



    testing (not supported)


    bandwidth bandwidth

    The channel bandwidth (GHz)



    central-frequency frequency

    The central frequency (THz) of the optical channel

    A value must be specified.

    A valid grid value from 191.35 to 196.10.

    Use the show dol fixed-grid command to see the valid grid values.


    central-wavelength wavelength

    The central wavelength (nm) of the optical channel

    The wavelength is automatically set based on the configured central-frequency setting.

    Note: Do not set this parameter directly.

    A valid grid value from 1528.77 to 1566.72


    custom1, custom2, custom3 string

    Customizable text field for operator's use

    0 to 255 characters

    An empty string

    ol-id string

    Customizable text identifying the optical layer managed object

    0 to 32 characters

    An empty string

    Required Privilege Level
