Configuration procedure

Configure Device A:

# Configure Ten-GigabitEthernet 1/0/1 to operate in active Ethernet OAM mode, and enable Ethernet OAM for it.

<DeviceA> system-view
[DeviceA] interface ten-gigabitethernet 1/0/1
[DeviceA-Ten-GigabitEthernet1/0/1] oam mode active
[DeviceA-Ten-GigabitEthernet1/0/1] oam enable

# Set the errored frame event detection window to 20000 milliseconds, and set the errored frame event triggering threshold to 10.

[DeviceA-Ten-GigabitEthernet1/0/1] oam errored-frame window 200
[DeviceA-Ten-GigabitEthernet1/0/1] oam errored-frame threshold 10
[DeviceA-Ten-GigabitEthernet1/0/1] quit

Configure Device B:

# Configure Ten-GigabitEthernet 1/0/1 to operate in passive Ethernet OAM mode (the default), and enable Ethernet OAM for it.

<DeviceB> system-view
[DeviceB] interface ten-gigabitethernet 1/0/1
[DeviceB-Ten-GigabitEthernet1/0/1] oam mode passive
[DeviceB-Ten-GigabitEthernet1/0/1] oam enable
[DeviceB-Ten-GigabitEthernet1/0/1] quit

Verify the configuration:

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
-----------[Ten-GigabitEthernet1/0/1] -----------
 Local link status   : UP
 Event statistics
   Link fault        : Not occurred
   Dying gasp        : Not occurred
   Critical event    : Not occurred

The output shows that no critical link event occurred on the link between Device A and Device B.

Use the display oam link-event command to display the statistics of Ethernet OAM link events. For example:

# Display Ethernet OAM link event statistics of the local end of Device A.

[DeviceA] display oam link-event local
------------ [Ten-GigabitEthernet1/0/1] -----------
 Link status: UP
 OAM local errored frame event
   Event time stamp        : 5789 x 100 milliseconds
   Errored frame window    : 200 x 100 milliseconds
   Errored frame threshold : 10 error frames
   Errored frame           : 13 error frames
   Error running total     : 350 error frames
   Event running total     : 17 events

The output shows the following:

350 errors occurred after Ethernet OAM is enabled on Device A.
17 errors were caused by error frames.
The link is unstable.
