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 : GigabitEthernet1/0/1
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.
# 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 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.
