Example
Run the
display cfm remote-mep
command. If the "Trigger If-down" field for the RMEP is
displayed as "enable", it means that the configuration succeeds.

4.13 Configuring Association Between Ethernet CFM and an
Interface (Triggering the Physical Status of the Interface
Associated with Ethernet CFM to Become Down)
After the association between Ethernet CFM and an interface is configured in the OAM
management view, local Ethernet CFM can detect a fault and then notify the OAM management
module of the fault. This triggers the physical status of the interface associated with Ethernet
CFM to become Down. In addition, when the physical status of an interface becomes Down, the
OAM management module notifies Ethernet CFM of the fault, and Ethernet CFM sends Ethernet
CFM messages carrying fault information to the remote device.
4.13.1 Establishing the Configuration Task
Before configuring the association between Ethernet CFM and an interface, you must enable
Ethernet CFM globally on each device and enable EFM in the interface view of each outgoing
interface.
Applicable Environment
, Ethernet CFM is enabled on PE1 and PE2. When a fault occurs on a
link between PEs, a CE needs to detect the fault to ensure reliable service transmission. In this
case, the associations between Ethernet CFM and interfaces need to be configured. Take PE2
as an example. When detecting a link fault, Ethernet CFM notifies the OAM management
module of the fault on PE2. This triggers the physical status of GE 1/0/2 associated with Ethernet
CFM to become Down. CE2 can then detect the fault and switch traffic to a backup path, which
ensures reliable service transmission.
