Displaying transceiver module information
Use the display transceiver interface command to display the key parameters of transceiver modules, including the transceiver module type, connector type, central wavelength of the transmit laser, signal transmission distance, and vendor name.
To display transceiver module information:
Task |
Command |
Remarks |
Display key parameters of transceiver modules. |
display transceiver interface [ interface-type interface-number ] |
Available for all transceiver modules. |
Diagnosing transceiver modules
The router provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:
· Check the alarms on the transceiver module to identify the fault source.
· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.
To diagnose a transceiver module:
Task |
Command |
Remarks |

display transceiver alarm interface [ interface-type interface-number ] |
Available for all transceiver modules. |
For more information about transceiver module-rated commands, see the command references for the router.
Saving the running configuration
IMPORTANT: You must save the running configuration to a .cfg configuration file. |
You can use one of the following methods to save the running configuration:
· Fast mode—Use the save command without the safely keyword. In this mode, the router directly overwrites the target next-startup configuration file. If a reboot or power failure occurs during this process, the next-startup configuration file is lost. You must specify a new startup configuration file after the router reboots.
· Safe mode—Use the save command with the safely keyword. Safe mode is slower than fast mode, but more secure. In safe mode, the system saves the configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot or power failure occurs during the save operation, the next-startup configuration file is still retained. Use the safe mode if the power source is not reliable or you are remotely configuring the router.
To save the running configuration:
Task |
Command |
Remarks |
Save the running configuration to a configuration file, without specifying the file as a next-startup configuration file. |
save file-url [ all | slot slot-number ] |
Use either approach. Available in user view. |
Save the running configuration to a configuration file in the root directory of the storage medium, and specify the file as a next-startup configuration file. |
save [ safely ] |
Rebooting the router or a module
CAUTION: · If the main system software image file does not exist, do not use the reboot command to reboot the router. Specify the main system software image file first, and then reboot the router. · The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the router prompts "REBOOT IN ONE MINUTE" and reboots in one minute. · If you are performing file operations when the router is to be rebooted, the system does not execute the reboot command for security. |
To reboot the router or a module, use one of the following methods:
· Reboot the router at the CLI.
¡ Reboot the router immediately by using the reboot command.
¡ Schedule a reboot to occur at a specific time or date or after a delay by using the schedule reboot command.
· Power off and then power on the router. This method cuts off the power of the router forcibly, which might cause data loss and hardware damage. It is the least-preferred method.
To reboot a module or the router immediately:
Task |
Command |
Remarks |
Reboot a module or the router immediately. |
reboot [ slot slot-number ] |
If you do not specify the slot slot-number option, the command reboots the router (including the RFUs and interface modules). Available in user view. |
To schedule a reboot:
