Chapter 5 Configuring Transponder Line Card Interfaces
Configuring Laser Shutdown
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 line card,
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 transparent 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
Step 1
Switch(config)# interface transparent
slot/subcard/port
Switch(config-if)#
Selects the transparent interface to configure and
enters interface configuration mode.
Step 2
Switch(config-if)# [no] laser control forward
enable
Configures forward laser control on the interface. The
default state is disabled.
Step 3
Switch(config-if)# exit Returns to global configuration mode.
Step 4
Switch(config)# interface wave slot/subcard
Switch(config-if)#
Selects the wave interface to configure and enters
interface configuration mode.
Step 5
Switch(config-if)# [no] laser control forward
enable
Configures forward laser control on the interface. The
default state is disabled.
