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-summa
ry 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-summa
ry
{
window window
|
threshold threshold
}
*
Optional
By default, the window size is
600 (in unit of 100 ms), and the
alarm threshold is 1 second.
Enable the error symbol period
alarm function
alarm oam
error-symbol-period enable
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.
