[Sysname] interface onu 3/0/1:1 
[Sysname-Onu3/0/1:1] alarm oam error-symbol-period enable 
alarm oam error-frame-period 
Syntax 
alarm oam error-frame-period { window window | threshold threshold } * 
undo alarm oam error-frame-period { window | threshold } 
View 
OLT port view, ONU port view, FTTH view 
Default Level 
2: System level 
Parameters 
window window: Specifies the window size, in the range 0 to 4294967295 (2
32
-1) seconds. By default, 
the window size is 1 second. 
threshold  threshold: Specifies the alarm threshold, in the range 1 to 4294967295 (2
32
-1) frames. By 
default, the threshold is 20 frames.
 
Description 
Use the alarm oam error-frame-period command to configure the corresponding window size and 
alarm threshold. 
Use the undo alarm oam error-frame-period command to restore the default window size and alarm 
threshold. 
The system generates an error frame period alarm when the number of error frames in a specific time 
period (that is, the window size) exceeds the corresponding predefined threshold. 
Related commands: alarm oam error-frame-period enable.  
 
 
 
When the alarm threshold is set to 0, large amount of alarms are generated immediately. Since 
alarm events are carried in the OAM packets, large amount of OAM packets are generated. In this 
case, OAM packets may be lost. 
 
The commands here take effect only for OAM 2.0 and above.  
 
Examples 
# Set the window size and alarm threshold for error frame period to 2 seconds and 30 frames on ONU 
1/0/1:1.
