4.18.5 Example for Configuring Association Between an EFM OAM
Module and an Interface
If association between an EFM OAM module and an interface is configured on a device, when
the EFM OAM module detects a fault, the EFM OAM module on the local device sends a fault
notification message to the OAM management module and triggers the physical status of the
interface bound to the EFM OAM module to go Down. When the physical status of the interface
becomes Down, the OAM management module sends a fault notification message to the EFM
OAM module. Then the EFM OAM module sends the fault notification message to the remote
device.
Networking Requirements
As shown in
Eth 0/0/2 on Switch B becomes Down, the EFM OAM module reports the fault to Eth 0/0/1 on
Switch C through the association mechanism. Then Eth 0/0/1 is triggered to go Down.
