Use the display oam configuration command to display the Ethernet OAM configuration. For
example:
# Display the Ethernet OAM information on Switch A.
[SwitchA] display oam configuration
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
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.
# Display the statistics of Ethernet OAM critical link events on all the ports of Switch A.
[SwitchA] display oam critical-event
Port : GigabitEthernet4/0/1
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 Switch A and Switch B.
# Display Ethernet OAM link event statistics of the remote end of Switch B.
[SwitchB] display oam link-event remote
Port :GigabitEthernet4/0/1
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 is enabled on Switch A, 17 of which
are caused by error frames. The link is instable.
