[SwitchA-Ethernet0/0/1] efm enable
[SwitchA-Ethernet0/0/1] quit
# Enable EFM OAM on Eth 0/0/1 of Switch B.
[SwitchB] interface ethernet 0/0/1
[SwitchB-Ethernet0/0/1] bpdu enable
[SwitchB-Ethernet0/0/1] efm enable
[SwitchB-Ethernet0/0/1] quit
# 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.
[SwitchB] display efm session interface ethernet 0/0/1

Step 2 Enable EFM OAM remote loopback.
# Enable EFM OAM remote loopback on Switch B.
[SwitchB] interface ethernet 0/0/1
[SwitchB-Ethernet0/0/1] efm loopback start
[SwitchB-Ethernet0/0/1] quit
# Verify the configuration.
Run the display efm session command on Switch B. If the EFM OAM protocol on Eth 0/0/1 is
in Loopback (control) state, that is, Eth 0/0/1 initiates remote loopback, the configuration is
successful. The displayed information is as follows:
[SwitchB] display efm session interface ethernet 0/0/1
Interface
----------------------------------------------------------------------
Ethernet0/0/1
Run the display efm session command on Switch A. If the EFM OAM protocol on Eth 0/0/1 is
in Loopback (be controlled) state, that is, Eth 0/0/1 responds to remote loopback, it indicates
that the configuration is successful. The displayed information is as follows:
[SwitchA] display efm session interface ethernet 0/0/1
Interface
----------------------------------------------------------------------
Ethernet0/0/1
Step 3 Send test packets from Switch B to Switch A.
[SwitchB] test-packet start interface ethernet 0/0/1
Please wait..............
Info: The test is completed.
Step 4 Check the returned test packets on Switch B.
[SwitchB] display test-packet result
