Ethernet OAM configuration example
Network requirements
On the network shown in Figure 2 , perform the following operations:
• Enable Ethernet OAM on Router A and Router B to auto-detect link errors between the two routers.
• Monitor the performance of the link between Router A and Router B by collecting statistics about the
error frames received by Router A.

Configuration procedure
1. Configure Router A:
# Configure GigabitEthernet 4/1/2 to operate in passive Ethernet OAM mode and enable
Ethernet OAM for it.
<RouterA> system-view
[RouterA] interface GigabitEthernet 4/1/2
[RouterA-GigabitEthernet4/1/2] oam mode passive
[RouterA-GigabitEthernet4/1/2] oam enable
[RouterA-GigabitEthernet4/1/2] quit
# Set the errored frame detection interval to 20 seconds and set the errored frame event triggering
threshold to 10.
[RouterA] oam errored-frame period 20
[RouterA] oam errored-frame threshold 10
2. Configure Router B:
