4.7 Configuring Association Between an EFM OAM Session
and an Interface (Triggering the Physical Status of the
Interface Associated with the EFM OAM Session to Become
Down)
After the association between an EFM OAM session and an interface is configured in the OAM
management view, the local EFM OAM session detects a fault and then notifies the OAM
management module of the fault. This triggers the physical status of the interface associated
with the EFM OAM session to become Down. In addition, when the physical status of an
interface becomes Down, the OAM management module notifies the EFM OAM session of the
fault. The EFM OAM session can then send fault information to the remote device.

4.7.1 Establishing the Configuration Task

Before configuring the association between an EFM OAM session and an interface, you must
enable EFM OAM globally on each device and enable EFM in the interface view of each
outgoing interface.
Applicable Environment
As shown in
between PEs, a CE needs to detect the fault to ensure reliable service transmission. In this case,
the associations between EFM OAM sessions and interfaces can be configured. Take PE2 as an
example. When an EFM OAM session detects a link fault, the EFM OAM session on PE2 notifies
the OAM management module of the fault. This triggers the physical status of GE 0/0/2
associated with the EFM OAM session to become Down. CE2 can then detect the fault and
switch traffic to a backup path, which ensures reliable service transmission.
