[RouterB] interface gigabitethernet 2/0/1
[RouterB-GigabitEthernet2/0/1] efm enable
[RouterB-GigabitEthernet2/0/1] quit
# Verify the configuration.
Run the display efm session command. If the EFM OAM protocol on the interface is in the
Detect state, it means that the configuration succeeds. EFM OAM is correctly configured on
Router A and Router B, and GE 2/0/1 and GE 1/0/1 succeed in negotiation and enter the Detect
state. For example, the EFM OAM state on GE 2/0/1 on Router B is displayed as follows:
[RouterB] display efm session interface gigabitethernet 2/0/1
Interface

GigabitEthernet2/0/1
Step 2 Configure EFM OAM remote loopback.
# Enable remote loopback on Router B.
[RouterB] interface gigabitethernet 2/0/1
[RouterB-GigabitEthernet2/0/1] efm loopback start
[RouterB-GigabitEthernet2/0/1] quit
# Verify the configuration.
Run the display efm session command on Router B. If the EFM OAM protocol on GE 2/0/1 is
in the loopback (control) state, that is, GE 2/0/1 initiates remote loopback, it means that the
configuration succeeds. The displayed information is as follows:
[RouterB] display efm session interface gigabitethernet2/0/1
Interface
----------------------------------------------------------------------
GigabitEthernet2/0/1
Run the display efm session command on Router A. If the EFM OAM protocol on GE 1/0/1 is
in the loopback (be controlled) state, that is, GE 1/0/1 responds to remote loopback, it means
that the configuration succeeds. The displayed information is as follows:
[RouterA] display efm session interface gigabitethernet1/0/1
Interface
----------------------------------------------------------------------
GigabitEthernet1/0/1
Run the display efm session command on RouterB. If the Loopback IgnoreRequest is no, that
is the GE1/0/1 responds to the remote loopback. The displayed information is as follows:
[RouterB] display efm session interface gigabitethernet2/0/1
