Displaying alarm and diagnosis information for a transceiver module
The device provides the alarm function and digital diagnosis function for transceiver modules. When a
transceiver module fails or inappropriately work, you can check for alarms present on the transceiver
module to identify the fault source or examine the key parameters monitored by the digital diagnosis
function, including the temperature, voltage, laser bias current, TX power, and RX power.
Perform the following commands in any view to diagnose transceiver modules:
To do… Use the command…
Display alarms present on transceiver modules
display transceiver alarm interface [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
Display the present measured values of the digital
diagnosis parameters for pluggable transceivers
display transceiver diagnosis interface [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
NOTE:
The display transceiver diagnosis interface command cannot display information for some transceiver
modules.

Configuring a software exception handling method
Configuring an exception handling method
By default, an SRPU automatically reboots when instruction error, illegal address error, data overflow,
null pointer, reset, or any other software anomaly occurs. You can also configure the SRPUs to stay in the
error condition without taking any protective action to preserve the error information for identifying the
problem.
Follow these steps to configure a software exception handling method for SRPUs:
To do… Use the command… Remarks
