Enable the ONU over limitation 
alarm function 

Optional 
The system generates an ONU 
over limitation alarm when the 
total number of ONUs 
connected with the OLT 
exceeds the limit. 
By default, this function is 
enabled. 

 

Follow these steps to configure alarms on an ONU port: 

Enter system view 

 

— 

Enter ONU port view 

 onu 

 

— 

Enable the error symbol period 
alarm function 

 

Optional 
The system generates an error 
symbol period alarm when the 
number of error frames in a 
specific period (that is, the 
window size) exceeds the 
corresponding predefined 
threshold. 
By default, this function is 
enabled. 

Enable the error frame period 
alarm function 

Optional 
The system generates an error 
frame period alarm when the 
number of error frames in a 
specific period (that is, the 
window size) exceeds the 
corresponding predefined 
threshold. 
By default, this function is 
enabled. 

Configure the window size and 
threshold for error frame period 
alarms 

 { window 

 | threshold threshold } 

* 

Optional 
When the alarm threshold is set 
to 0, a lot of alarms are 
generated immediately. Since 
alarm events are carried in the 
OAM packets, a lot of OAM 
packets are generated. In this 
case, OAM packets may be 
lost. 
By default, the window size is 1 
second, and the alarm 
threshold is 20 frames.
