Syntax

Description

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.

Parameter

Description

Range

Default Value

och:location_id

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

where:

  • channel is an alphanumeric string up to 32 characters long

None

admin-status status

The administrative status of the optical channel

up

down

testing (not supported)

up

bandwidth bandwidth

The channel bandwidth (GHz)

50

50

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.

None

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

None

custom1, custom2, custom3 string

Customizable text field for operator's use

0 to 255 characters

An empty string
