Usage Guidelines

Before configuring the parameters of an OTUk controller, ensure that the OTUk controller is created.

Examples

The following example shows how to access an interface instance of an OTU1 controller on port 1.

Command History

Release Modification
5.2.1

This command was introduced.

Examples

The following example shows how to configure GCC on the OTU1 controller. 

Router(config)# controller OTU1 0/0/0/1
Router(config-otu1)# gcc0

Usage Guidelines

You can configure loopback on an OTUk controller only if the secondary administrative state of the controller is maintenance.

Examples

The following example shows how to configure a terminal loopback on the OTU1 controller. 

Router(config)# controller OTU1 0/0/0/1

Usage Guidelines

The primary administrative state of an OTUk controller must be no shutdown if you want to configure a second administrative state of the controller. The secondary administrative state of OTUk controllers is inherited by the corresponding optics controllers. You cannot modify the secondary administrative state of an OTUk controller if a loopback is already configured on it.

The following example shows how to configure the secondary administrative state as in service of the OTU1 controller. 

Router(config)# controller OTU1 0/0/0/1

value

Signal degrade threshold. The valid range of signal failure is from 3 to 9. The default value is 6.

Command Default

By default, threshold for signal failure is 3 and signal degrade is 6 for a given OTUk controller.
