Configuring Ethernet Cfm On Pes On A Vll - Huawei NetEngine80E Configuration Manual - Reliability

HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
PE1 and PE2 are connected through a VLL. PEs receive packets with double VLAN tags. To
check connectivity between PEs, you need to configure sub-interfaces for QinQ VLAN tag
termination on AC interfaces of the PEs to bind L2VCs and then configure Ethernet CFM on
the PEs.
Pre-configuration Tasks
Before associating Ethernet CFM with VLL by using sub-interfaces for QinQ VLAN tag
termination, complete the following tasks:

8.13.2 Configuring Ethernet CFM on PEs on a VLL

Ethernet CFM provides end-to-end connectivity detection, fault notification, fault verification,
and fault location. Providing the preceding functions, Ethernet CFM can be used to detect the
connectivity of the entire network and locate faults. This helps improve the reliability of the
network.
Context
Do as follows on the PEs:

For details, refer to the chapter "VLL Configuration" in the HUAWEI NetEngine80E/40E
Router Configuration Guide - VPN.
Configuring sub-interfaces for QinQ VLAN tag termination to access the VLL
For details, refer to the chapter "QinQ Configuration" in the HUAWEI NetEngine80E/
40E Router Configuration Guide - LAN Access and MAN Access.
8.6 Configuring Basic Ethernet CFM
Data
Destination address and VC ID of an L2VC
Name of an interface to which an L2VC is bound
Names of MDs and MAs
ID of a MEP, name of the interface on which the MEP resides, and type of the MEP
(Optional) ID of an RMEP and MAC address of the interface where the RMEP resides
Interval for MEPs sending CCMs in an MA
NOTE
l When performing 802.1ag MAC trace between PEs, you cannot specify the outbound interface for
sending trace packets.
l The current MA must be associated with an L2VC, and the type of the MEP must be inward-facing.
