If the bidirectional association between Ethernet CFM and an interface is configured on PE2,
the OAM management module sends fault information to Ethernet CFM associated with GE
0/0/2 when GE 0/0/2 goes Down on PE2 connected to CE2. Ethernet CFM messages carrying
fault information are sent to the OAM module on PE1, which triggers the physical status of
GE 0/0/2 on PE1 to become Down. CE1 can then detect the fault and switch traffic to a backup
path, which ensures reliable service transmission.
Pre-configuration Tasks
Before configuring the association between Ethernet CFM and an interface (in the OAM
management view), complete the following task:

4.13.2 Configuring Association Between Ethernet CFM and an
Interface
Ethernet CFM can be associated with only one interface. When Ethernet CFM is associated with
an interface, it cannot be associated with another interface. In addition, the interface cannot be
associated with Ethernet CFM on another device.
