[SwitchA] interface ethernet 0/0/1
[SwitchA-Ethernet0/0/1] efm mode passive
[SwitchA-Ethernet0/0/1] bpdu enable
Step 3 Enable EFM OAM on Eth 0/0/1 of Switch B and Eth 0/0/1 of Switch A.
# Enable EFM OAM on Eth 0/0/1 of Switch A.
[SwitchA-Ethernet0/0/1] efm enable
[SwitchA-Ethernet0/0/1] quit
# Enable EFM OAM of Eth 0/0/1 on Switch B.
[SwitchB] interface ethernet 0/0/1
[SwitchB-Ethernet0/0/1] efm enable
[SwitchB-Ethernet0/0/1] bpdu enable
Step 4 Configure Eth 0/0/1 of Switch B to detect the errored frames, errored codes, and errored frame
seconds.
# Configure Eth 0/0/1 of Switch B to detect the errored frames.
[SwitchB-Ethernet0/0/1] efm error-frame period 5
[SwitchB-Ethernet0/0/1] efm error-frame threshold 5
[SwitchB-Ethernet0/0/1] efm error-frame notification enable
# Configure Eth 0/0/1 of Switch B to detect the errored codes.
[SwitchB-Ethernet0/0/1] efm error-code period 5
[SwitchB-Ethernet0/0/1] efm error-code threshold 5
[SwitchB-Ethernet0/0/1] efm error-code notification enable
# Configure n Eth 0/0/1 of Switch B to detect the errored frames seconds.
[SwitchB-Ethernet0/0/1] efm error-frame-second period 120
[SwitchB-Ethernet0/0/1] efm error-frame-second threshold 5
[SwitchB-Ethernet0/0/1] efm error-frame-second notification enable
[SwitchB-Ethernet0/0/1] quit
Step 5 Verify the configuration.
# If EFM OAM is configured correctly on Switch A and Switch B, Eth 0/0/1 and Eth 0/0/1 start
the handshake after negotiation. Run the display efm session command on Switch A or Switch
B, and you can find that the EFM OAM protocol is in detect state.

# Run the display efm command on Switch B. If the function of detecting errored frames, errored
codes, and errored frame seconds on Eth 0/0/1 is configured corrected, the following information
is displayed:
