–
An Ethernet CFM module sends a fault notification message to an EFM OAM module.
–
An EFM OAM module a fault notification message to an Ethernet CFM module.
–
An Ethernet CFM module and an EFM OAM module report faults to each other.
l
Association between Ethernet CFM modules
When the Ethernet CFM module detects a fault in an MA, the OAM management module
reports the fault to the bound MA at the other side. The fault report mode can be the
following:
–
An Ethernet CFM module at one side sends a fault notification message to an Ethernet
CFM module at the other side.
–
Ethernet CFM modules at both sides report faults to each other.
4.3 Configuring Basic EFM OAM
By configuring basic EFM OAM functions, you can detect connectivity of the direct link between
devices.
4.3.1 Establishing the Configuration Task
Before configuring basic EFM OAM functions, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
Applicable Environment
, you can perform the configuration task to detect the connectivity
between two directly connected devices.
