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 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 easy diagnosis.

To display the alarm information about transceiver modules:

Task Command

Remarks

Display the current alarm
information of 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 the failed MPU to recover from the error condition.

maintain—The MPU stays in the error condition so you can collect complete data, including error
messages, for diagnosis. In this approach, you must manually reboot the firewall
