dol och-xcon

 

Syntax

Description

This command configures the specified DOL optical channel cross-connect on a ROADM node. If the optical channel cross-connect does not exist, the optical channel cross-connect is created. An optical channel cross-connect specifies how wavelengths are routed within a ROADM node.

Note

The cross-connect endpoints and the intra-nodal fiber connections must exist before you can create the corresponding inter-module cross-connect.

Note

This command automatically creates optical channels on client ports as needed.

Options

Parameter

Description

Range

Default Value

och-xcon endpoint1 endpoint2

The two endpoints of the cross-connect.

A cross-connect can be configured between the following endpoints:

  • passthrough: an optical channel on a ROADM module line port to/from an optical channel on another ROADM module line port

  • passthrough (split ROADM node): an optical channel on a ROADM module line port to/from an optical channel on the same ROADM module's client port

  • add/drop: an optical channel on a ROADM module line port to/from an interface on a UFM on the same system

  • add/drop (alien wavelength): an optical channel on a ROADM module line port to/from an optical channel on the same ROADM module's client port

The following are the valid endpoints:

  • an existing optical channel on a line port (for example, och:1/6/0/L1/chan140)

  • an optical channel on a client port (for example, och:1/6/0/C1/chan140)

    Note: If the optical channel on the client port does not exist, it is automatically created. This type of endpoint is for use with a split ROADM node or when connecting to an external endpoint (alien wavelength).

  • an existing OTU4 or 100GbE interface on a UFM (for example, otu4:1/10/2/1)

Additional Information

This command is used to set up cross-connects for both passthrough and add/drop connections.

Passthrough connections are typically set up between optical channels on line ports on different ROADM modules. On split ROADM nodes, however, passthrough connections are set up between an optical channel on a line port and an optical channel on one of the same module's client ports.

Add/drop connections are set up between an optical channel on the add/drop ROADM module line port and a UFM interface.

Add/drop connections can also be set up between an optical channel on a line port and an optical channel on one of the same module's client ports. This is for alien wavelengths only.

In all cases, the endpoints must be configured with the same central frequency.

Additionally, the following fiber connections must exist:

Type of connection

Fiber connection required

Passthrough

A fiber-conn must exist between the client ports connecting the two ROADM modules.

Add/drop to a UFM through a multiplexer/demultiplexer

A fiber-conn must exist between the line interface on the multiplexer/demultiplexer and the add/drop client port on the ROADM module.

A fiber-conn must exist between the UFM interface and the corresponding (same frequency) client interface on the multiplexer/demultiplexer.

Add/drop to an external endpoint (alien wavelength) through a multiplexer/demultiplexer

A fiber-conn must exist between the line interface on the multiplexer/demultiplexer and the add/drop client port on the ROADM module.

After this command is committed, the required client port optical channels are automatically created.

Sample Output

The following creates a passthrough cross-connect, and shows the optical channels that are automatically created on the client ports. The channel name of each automatically-created optical channel is set to the channel name of the corresponding optical channel endpoint on the same module. This is shown below:
