Example
The following example shows how to display the attenuation configuration of a voafilterin subinterface:
Switch# show interfaces voafilterin 2/1/0.2
voaFilterIn2/1/0.2 is up, line protocol is up
Hardware is voaFilterIn Port
Port Transmit (Tx) Support: False
Port Receive (Rx) Support: True
VOA This Port operates on: 1
Minimum settable Attenuation: 3.7dB
Maximum settable Attenuation: 30.0dB
Current set Attenuation: 20.0dB
Light Quality: Low Warning Threshold Exceeded
Current Output Power: -16.3dBm
Low Alarm Threshold: -20.0dBm
Low Alarm Threshold Severity: major (Default Value)
Low Warning Threshold: -15.0dBm
Low Warning Threshold Severity: not-alarm (Default Value)
High Warning Threshold: -10.0dBm
High Warning Threshold Severity: not-alarm (Default Value)
High Alarm Threshold: -5.0dBm
High Alarm Threshold Severity: major (Default Value)
The following example shows how to display the attenuation configuration of a voain in te rface :
Switch# show interfaces voain 7/1/0
voaIn7/1/0 is up, line protocol is down
Hardware is voaIn Port
Port Transmit (Tx) Support: False
Port Receive (Rx) Support: True
VOA This Port operates on: 1
Minimum settable Attenuation: 1.7dB
Maximum settable Attenuation: 30.0dB
Current set Attenuation: 1.7dB
Light Quality: Loss of Light/Low Alarm Threshold Exceeded
Current Output Power: -256.0dBm
Low Alarm Threshold: -29.0dBm (Default Value)
Low Alarm Threshold Severity: major (Default Value)
Low Warning Threshold: -20.0dBm
Low Warning Threshold Severity: not-alarm (Default Value)
High Warning Threshold: -5.0dBm
High Warning Threshold Severity: not-alarm (Default Value)
High Alarm Threshold: 0.0dBm
High Alarm Threshold Severity: major (Default Value)
