To display transceiver module information:
Purpose Command Remarks
Display key parameters of the transceiver
module in a specified interface display transceiver interface
[ interface-type interface-number ] Available for all
transceiver modules
Displaying the alarming information or fault detection
parameters for a transceiver module
The system outputs alarm information for you to locate and troubleshoot faults of transceiver modules. For
the H3C-customized transceiver modules, the system can also monitor the key parameters, such as
temperature, voltage, laser bias current, TX power, and RX power. When these parameters are abnormal,
you can take corresponding measures to prevent transceiver module faults.

Solving system faults
Solving system faults
When the system detects faults (such as system instruction faults, invalid addresses, data overflow, null
pointers, and division by zero operations) during the operation of the active MPU or standby MPU, you
can solve the problem in one of the following methods:
• Reboot—Rebooting the failed MPU so that the MPU restores to normal operational status.
• Maintain—Maintaining the current status of the failed MPU so that the system does not take any
restoration measures. Some software faults are hard to reproduce, and the printed information will
be lost after the router reboots. In this case, you can maintain the current status of the router,
facilitating fault location.
To solve system faults:
Step Command Remarks
1. Enter system view system-view N/A
2. (Optional)Specify the system fault solving method
for the active MPU and standby MPU
system-failure { maintain |
reboot } The default method is
reboot.
Viewing the system fault solving method
Use the display system-failure command to display the system fault solving method.
