To do... Use the command... Remarks
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.
Configure the window size and
thresholds for error symbol period
alarms
alarm oam error-symbol-period
{ window-high windowhigh |
window-low windowlow |
threshold-high thresholdhigh |
threshold-low thresholdlow } *
Optional
When both the upper limit and the
lower limit of the alarm threshold
are 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.
The window size and threshold
values specified in this command
comprise two parts, a significant
part and an insignificant part, both
16 bits in length.
By default, the window size is 1
second, and the alarm threshold is
20 bytes.
Enable the local link fault alarm
function
alarm oam local-link-fault
enable
Optional
The system generates a local link
fault alarm when the inbound
direction of the local data terminal
becomes faulty.
Enable the registration error alarm
function
alarm registration-error enable
Optional
The system generates a
registration error alarm when an
error occurs during the registration
of an ONU.
By default, this function is enabled.
