Configuration of the link event window/threshold :
--------------------------------------------------------------------------
Errored-symbol Event period(in seconds) : 1
Errored-symbol Event threshold : 1
Errored-frame Event period(in seconds) : 20
Errored-frame Event threshold : 10
Errored-frame-period Event period(in ms) : 1000
Errored-frame-period Event threshold : 1
Errored-frame-seconds Event period(in seconds) : 60
Errored-frame-seconds Event threshold : 1
According to the above output information, the detection period of errored frame events is 20 seconds,
the detection threshold is 10 seconds, and all the other parameters use the default values.
You can use the display oam critical-event command to display the statistics of Ethernet OAM
critical link events. For example:
# Display the statistics of Ethernet OAM critical link events on all the ports of Device A.
[DeviceA] display oam critical-event
Port : GigabitEthernet2/0/1
Link Status : Up
Event statistic :
-------------------------------------------------------------------------
Link Fault :0 Dying Gasp : 0 Critical Event : 0
According to the above output information, no critical link event occurred on the link between Device A
and Device B.
You can use the display oam link-event command to display the statistics of Ethernet OAM link error
events. For example:
# Display Ethernet OAM link event statistics of the remote end of Device B.
[DeviceB] display oam link-event remote
Port :GigabitEthernet2/0/1
Link Status :Up
OAMRemoteErrFrameEvent : (ms = milliseconds)
---------------------------------------------------------------------
Event Time Stamp : 5789 Errored FrameWindow : 10(100ms)
Errored Frame Threshold : 1 Errored Frame : 3
Error Running Total : 35 Event Running Total : 17
The above information indicates that 35 errors occurred since Ethernet OAM is enabled on Device A,
17 of which are caused by error frames. The link is instable.
