To do... Use the command... Remarks
Configure the threshold of LLID
mismatch frame alarms
alarm llid-mismatch threshold
threshold
Optional
5000 frames by default
Enable the local stable alarm
function
alarm local-stable enable
Optional
The system generates a local
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). A local stable alarm
is generated by the OLT side.
By default, this function is enabled.
Enable the critical event alarm
function
alarm oam critical-event enable
Optional
The system generates a critical
event alarm when one of the
following critical events occurs:
local link fault and dying gasp.
Enable the dying gasp alarm
function
alarm oam dying-gasp enable
Optional
The system generates a dying
gasp alarm when a system error, a
data loading error or any other
nonreversible error occurs.
Enable the error frame period
alarm function alarm oam error-frame-period
enable
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.
Configure the window size and
threshold for error frame period
alarms
alarm oam error-frame-period
{ 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 1
second, and the alarm threshold is
20 frames.
