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.
