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
Configuration of the timer :
--------------------------------------------------------------------------
Hello timer(in ms) : 1000
Keepalive timer(in ms) : 5000
The output shows that 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 : GigabitEthernet1/0/1
Link Status : Up
Event statistic :
-------------------------------------------------------------------------
Link Fault :0 Dying Gasp : 0 Critical Event : 0
The output shows that 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 :GigabitEthernet1/0/1
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 output shows that 35 errors occurred since Ethernet OAM was enabled on Device A, 17 of which are
caused by error frames. The link is unstable.
