Verifying transceiver modules
To verify transceiver modules, 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 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
Diagnosing transceiver modules
The firewall provides the alarm function for transceiver modules for diagnosis.
To display the alarm information about transceiver modules:
Task Command Remarks
Display the current alarm information for the
transceiver module in a specified interface. display transceiver alarm interface
[ interface-type interface-number ]
Available for all
transceiver modules

Troubleshooting system exceptions
Configuring the exception handling methods
You can use one of the following methods to handle system exceptions:
• reboot—The firewall reboots to recover from the error condition.

itself, so you can collect complete data, including error messages, for diagnosis.
To configure the exception handling method:
