Remarks
Optional
The system generates a dying
gasp alarm when a system
error, a data loading error, or
any other nonreversible errors
occur.
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.
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.
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.
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.
