To do... Use the command... Remarks
Configure the window size and
thresholds for error symbol
period alarms
alarm oam
error-symbol-period
{
window-high windowhigh

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.
Enable the remote stable alarm
function
alarm remote-stable enable
Optional
The system generates a
remote stable alarm when an
ONU misuse occurs in the
system, for example, when an
OAM 2.0 ONU and an OAM 3.3
ONU are mixed in the same
system. (All ONUs in the same
system must adopt the same
OAM version). This alarm is
generated at the ONU side and
will be reported to the OLT.
By default, this function is
enabled.
Enable the OAM
vendor-specific alarm function
alarm oam-vendor-specific
enable
Optional
This alarm is customized by
vendors.
By default, this function is
enabled.
