# Configure Switch B.
[SwitchB] interface xgigabitethernet 0/0/1
[SwitchB-XGigabitEthernet0/0/1] efm enable
[SwitchB-XGigabitEthernet0/0/1] quit
[SwitchB] interface xgigabitethernet 0/0/2
[SwitchB-XGigabitEthernet0/0/2] bpdu enable
[SwitchB-XGigabitEthernet0/0/2] efm enable
[SwitchB-XGigabitEthernet0/0/2] quit
# Configure Switch C.
[SwitchC] interface xgigabitethernet 0/0/2
[SwitchC-XGigabitEthernet0/0/2] efm enable
[SwitchC-XGigabitEthernet0/0/2] quit
Run the display efm session all command to check the EFM OAM status, and you can find that
EFM OAM is in detect state. Take the display on Switch B as an example.

Step 4 Configure association between EFM OAM modules.
[SwitchB] oam-mgr
[SwitchB-oam-mgr] oam-bind efm interface xgigabitethernet 0/0/1 efm interface
xgigabitethernet 0/0/2
In the OAM management view, run the display this command to check association. You can
find that there are two unidirectional association configuration records, whose directions are
mutually reverse.
[SwitchB-oam-mgr] display this
#
oam-mgr
oam-bind ingress efm interface XGigabitEthernet0/0/1 egress efm interface
XGigabitEthernet0/0/2
oam-bind ingress efm interface XGigabitEthernet0/0/2 egress efm interface
XGigabitEthernet0/0/1
#
Step 5 Verify the configuration.
# On SwitchC, enable the function of sending debugging information to a terminal.
<SwitchC> terminal logging
<SwitchC> terminal monitor
# Shut down XGE 0/0/1 on SwitchA and simulate link faults.
[SwitchA] interface xgigabitethernet 0/0/1
[SwitchA-XGigabitEthernet0/0/1] shutdown
# Fault messages between SwitchA and SwitchB are transmitted to SwitchC through the
association mechanism. Then alarms are generated on SwitchC.
