8.2.7 Associating EFM OAM with Ethernet CFM
By configuring the association between EFM OAM and Ethernet CFM, you can implement the
bidirectional fault notification.
Before You Start
Before configuring the association between EFM OAM and Ethernet CFM, familiarize yourself
with the usage scenario, complete the pre-configuration tasks, and obtain the required data.
Applicable Environment
IEEE 802.3ah is designed for the last mile of the Ethernet to detect the direct link between a CE
and a PE. IEEE 802.1ag is designed for a group of services or some specific network devices to
detect faults on the network. It functions between the following devices:
l
CE and CE
l
PE and PE
l
CE and PE
As shown in
, EFM OAM or Ethernet CFM runs between CE1 and PE1, and between
CE2 and PE2; Ethernet CFM runs between PE1 and PE2. Configure the association between
Ethernet OAMs. When a fault occurs on the link between CE1 and PE1, Ethernet CFM sends
alarms of the fault to CE2.
