Examples
Example: Displaying Threshold Violations
This example shows how to display the threshold violations for all transceivers on a Cisco ASR 901
router:
Router# show interfaces transceiver threshold violations
Rx: Receive, Tx: Transmit.
DDDD: days, HH: hours, MM: minutes, SS: seconds
Time since Last Known
Time in slot Threshold Violation Type(s) of Last Known
Port (DDDD:HH:MM:SS) (DDDD:HH:MM:SS) Threshold Violation(s)
--------- --------------- ---------------------- ----------------------
Gi0/10 0000:02:50:19 Not applicable Not applicable
Gi0/11 0000:02:51:15 Rx power low alarm
-31.0 dBm < -17.1 dBm
Example: Displaying Threshold Violations on a Specific Interface
This example shows how to display violations for the transceiver on a specific interface:
Router# show interfaces GigabitEthernet 0/9 transceiver
ITU Channel not available (Wavelength not available),
Transceiver is externally calibrated.
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).

Example: When Transceiver Monitoring is Disabled
This example shows how to disable transceiver monitoring for all transceivers:
Router(config-xcvr-type)# no monitoring
This example shows the sample output when transceiver monitoring is disabled:
Router# show interfaces transceiver detail
Transceiver monitoring is disabled for all interfaces.
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.
