debug: Displays the types of debugging information allowed to be output by the ONU on the OLT.  

log: Displays the log information generated by the ONU on the OLT.  

trap: Displays the trap information generated by the OLT on the ONU.  

severity: Severity level of the information that the ONU reports to the OLT. The severity levels include (in 

the descending order of priority):  

emergencies, alerts, critical, errors, warnings, notifications, information, and debugging.  

Use the onu-event  { debug | log | trap } enable level command to specify the ONU to report log, 

debugging, or trap information to the OLT.  

Use the undo onu-event { debug | log | trap } command to restore the default.  

By default, an ONU reports no information to the OLT.  

Note that: because a large number of ONUs are attached to an OLT, enabling ONUs to report 

information to the OLT may generate a large amount of traffic and thus cause congestion. Therefore, 

you are recommended to select the reported information types as required.  

# Configure the OLT attached to ONU 3/0/1:1 to report log information with severity levels higher than 

errors.
