4.16 Configuring Association Between Ethernet CFM and
SEP
This section describes how to configure association between Ethernet CFM and SEP.

4.16.1 Establishing the Configuration Task

Applicable Environment
Association between Ethernet CFM and SEP is configured on edge devices of the SEP segment.
When Ethernet CFM detects a fault on the upper-layer network, the edge device encapsulates a
fault message into a CFM protocol packet and sends it to the OAM management module. In
addition, the edge device triggers the physical status of the interface on the edge device bound
to Ethernet CFM to go Down.
When the interface on the edge device bound to Ethernet CFM becomes Down, the peer device
(on the SEP segment) of the edge device needs to send FLUSH-FDB packets to report the
topology change to other nodes on the SEP segment. After the nodes on the SEP segment receive
FLUSH-FDB packets, the blocking interface on the SEP segment needs to enter the forwarding
state and send FLUSH-FDB packets to trigger the updating of MAC address tables and ARP
tables of nodes on the SEP segment. In this manner, the lower-level network can detect faults
on the upper-level network and the reliability of service transmission is improved.
