If the bidirectional association between an EFM OAM session and an interface is configured on
a PE, when GE 0/0/2 that connects PE2 to CE2 goes Down, the OAM management module
sends fault information to the EFM OAM session associated with GE 0/0/2. EFM OAMPDUs
carrying the fault information are sent to the OAM management module on PE1, which triggers
the physical status of GE 0/0/2 to become Down. CE1 can then detect the fault and switch traffic
to a backup path, which ensures reliable service transmission.

4.7.2 Configuring Association Between an EFM OAM Session and
an Interface
One EFM OAM session is associated with only one interface. That is, when an interface is
associated with an EFM OAM session, the interface cannot be associated with another EFM
OAM session. In addition, when an EFM OAM session is associated with a specified interface,
the EFM OAM session cannot be associated with another interface.
