Configuring Laser Shutdown
This sections describes how to configure forward laser control and laser safety control on the
Cisco ONS 15530 transponder line card interfaces.
Note To function correctly, configure forward laser control on both the transparent and wave interfaces on
a transponder line card. For y-cable protection, forward laser control on both the transparent and
wave interfaces on both transponder line cards will be configured automatically.

Configuring Forward Laser Control

To configure forward laser control for transparent and wave interfaces on a transponder li ne ca rd,
perform the following steps, beginning in global configuration mode:
Caution Do not configure forward laser control when OFC is enabled. Combining these features interferes
with the OFC protocol.
Examples
The following example shows how to configure forward laser control for the transpare nt and wave
interfaces on a transponder line card:
Switch(config)# interface transparent 5/0/0
Switch(config-if)# laser control forward enable
Switch(config-if)# exit
Switch(config)# interface wave 5/0
Switch(config-if)# laser control forward enable
The following example shows how to configure forward laser control for an OSC wave interface:
Switch(config)# interface wave 0
Switch(config-if)# laser control forward enable
Command Purpose
Step1 Switch(config)# interface transparent
slot/subcard/port
Switch(config-if)#
Selects the transparent interface to configure and
enters interface configuration mode.
Step2 Switch(config-if)# [no] laser control forward
enable Configures forward laser control on the interface. The
default state is disabled.
Step3 Switch(config-if)# exit Returns to global configuration mode.
Step4 Switch(config)# interface wave slot/subcard
Switch(config-if)#
Selects the wave interface to configure and enters
interface configuration mode.
Step5 Switch(config-if)# [no] laser control forward
enable Configures forward laser control on the interface. The
default state is disabled.
