Configuring VOA Module Interfaces
The following steps describe the configuration tasks for optical amplification support on the
Cisco ONS 15530:
Step 1 Configure attenuation values (optional).
Step 2 Configure alarm thresholds (optional).
Configuring Attenuation
To configure the attenuation on a VOA module interface, perform the following steps:
Example
The following example shows how to configure attenuation on a voafilterin subinterface on a PB-OE
module:
Switch# configure terminal
Switch(config)# interface voafilterin 1/0/0.1
Switch(config-subif)# optical attenuation manual 20
The following example shows how to configure attenuation on a voain interface on a WB-VOA module:
Switch# configure terminal
Switch(config)# interface voain 1/0/0
Switch(config-if)# optical attenuation manual 30

Displaying the Attenuation Configuration

To verify the configuration of attenuation configuration, use the following EXEC comm an d:
Command Purpose
Step1 Switch# configure terminal
Switch(config)#
Enter global configuration mode.
Step2 Switch(config)# interface {voafilterin
slot/subcard/port.subinterface |
voain slot/subcard/port}
Switch(config-if)#
Selects the VOA interface to configure and enters
interface configuration mode.
Step3 Switch(config-if)# optical attenuation manual
value Specifies the value in units of 0.1dBm.
Command Purpose
show interfaces {voafilterin
slot/subcard/port.subinterface | voain
slot/subcard/port}
Displays the VOA module interface configuration.
