Enable the port bit error rate alarm
function
alarm port bit-error-rate enable
Optional
When both the total number of
error bits and bit error rate of the
data transferred between the OLT
and ONUs exceed the alarm
thresholds, a port bit error rate
alarm occurs.
By default, this function is enabled.
Enable the device fatal error alarm
function
alarm device-fatal-error enable
Optional
By default, this function is enabled.
Enable the frame error rate alarm
function
alarm frame-error-rate enable
Optional
When the total number of error
frames or the error frame rate of
the data transferred between the
OLT and ONUs exceeds the alarm
threshold, a frame error rate alarm
occurs.
By default, this function is enabled.
Configure the monitor direction
and threshold for frame error rate
alarms
alarm frame-error-rate
{ direction { uplink | downlink |
up-down-link } | threshold
threshold } *
Optional
By default, the monitor direction is
up-down-link , and the threshold
of frame error rate alarms is 1 (the
unit is 10 -9 ).
Enable the LLID mismatch frame
alarm function
alarm llid-mismatch enable
Optional
The system generates an LLID
mismatch frame alarm when the
time slots are used in disorder, that
is, an ONU uses another ONU's
time slot to forward data.
By default, this function is
disabled.
Configure the threshold for LLID
mismatch frame alarms
alarm llid-mismatch threshold
threshold
Optional
By default, the threshold of LLID
mismatch alarms is 5000 frames.
