window window: Specifies the window size, in the range 0 to 65535 seconds. By default, the window 

size is 10 seconds. 

threshold  threshold: Specifies the alarm threshold, in the range 1 to 4294967295 (2

32

-1) frames. By 

default, the threshold is 20 frames. 

 

Use the alarm oam error-frame command to configure the corresponding window size and alarm 

threshold. 

Use the undo alarm oam error-frame to restore the default window size and alarm threshold. 

The system generates an error frame 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 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.
