Errored-frame Event threshold
Errored-frame-period Event period(in ms)
Errored-frame-period Event threshold
Errored-frame-seconds Event period(in seconds)
Errored-frame-seconds Event threshold
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 link-event command to display the statistics about Ethernet OAM link
events and use the display oam critical-event command to display the Ethernet OAM configuration
information. 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
According to the above output information, no critical link event occurred on the link between Device A
and Device B.
# 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)

Error Running Total
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.
