Displaying Forward Laser Control Configuration

To display the forward laser control configuration of a transparent or wave interface, use the following
EXEC command:
Example
The following example shows how to display the forward laser control configuration for an interface:
Switch# show interfaces transparent 10/0/0
Transparent10/0/0 is administratively up, line protocol is up
Encapsulation: Sonet Rate: oc3
Signal monitoring: off
Time of last "monitor" state change never
Time of last "encapsulation" change 10:18:20
Forward laser control: On
Configured threshold Group: None
Loopback not set
Last clearing of "show interface" counters 10:18:20
Hardware is transparent
Configuring Laser Safety Control
To configure laser safety control on a wave interface, perform the following steps, beginning in glob al
configuration mode:
Note Use laser safety control only with line card protected and unprotected configurations. Enable laser
safety control on all the wave interfaces in the shelf, including the OSC.
Caution Do not configure laser safety control when OFC is enabled. Combining these features interferes with
the OFC safety protocol.
Example
The following example shows how to configure laser safety control on a wave interface:
Switch(config)# interface wave 8/0
Switch(config-if)# laser control safety enable
Command Purpose
show interfaces {transparent slot/subcard/port |
wave slot/subcard}Displays interface information.
Command Purpose
Step1 Switch(config)# interface wave slot/subcard}
Switch(config-if)#
Selects the wave interface to configure and enters
interface configuration mode.
Step2 Switch(config-if)# [no] laser control safety
enable Enables or disables laser safety control.
