Verifying transceiver modules

To verify transceiver modules, you can use the display transceiver interface command to display the key
parameters of the transceiver modules, including transceiver module type, connector type, central
wavelength of the laser sent, transfer distance, and vendor name.
To display the transceiver module information:
Task
Display key parameters of the
transceiver module in a specified
interface.

Diagnosing transceiver modules

The UTM device provides the alarm function for transceiver modules for diagnosis.
To display the alarm information about transceiver modules:
Task
Display the current alarm
information of the transceiver
module in a specified interface.

Troubleshooting system exceptions

Configuring the exception handling methods

You can use one of the following methods to handle system exceptions:
reboot—The UTM device reboots to recover from the error condition.
•
• maintain—The UTM device stays in the error condition and does not take any measure to recover
itself, so you can collect complete data, including error messages, for diagnosis.
To configure the exception handling method:
Step
1. Enter system view.
2. Configure the exception
handling method for the
system.

Displaying the exception handling method

Use the display system-failure command to display the exception handling method.
