To do... Use the command... Remarks
Enable the error frame alarm
function
alarm oam error-frame enable
Optional
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.
By default, this function is enabled.
Configure the window size and
threshold for error frame alarms
alarm oam error-frame { window
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 10
seconds, and the alarm threshold
is 20 frames.
Enable the error frame seconds
summary alarm function
alarm oam
error-frame-seconds-summary
enable
Optional
The system generates an error
frame seconds summary alarm
when the number of error frame
seconds (in an error frame second,
at least one error frame occurs) in
a specific time period (for example,
1 minute) exceeds the
corresponding predefined
threshold.
By default, this function is enabled.
Configure the window size and
threshold for error frame seconds
summary alarms
alarm oam
error-frame-seconds-summary
{ window window | threshold
threshold } *
Optional
By default, the window size is 600
(in unit of 100 ms), and the alarm
threshold is 1 second.
