Configuration Guide - Reliability
By sending test packets and waiting for a reply, you can test connectivity of the path between
devices and locate faults.
8.10 Associating Ethernet CFM with an Interface
The association between Ethernet CFM and an interface is used to detect faults of an active link
in the LACP static link aggregation group or in the manually-configured 1:1 active/standby link
aggregation group and then trigger the protection switchover.
8.11 Associating EFM OAM with Ethernet CFM
By configuring the association between EFM OAM and Ethernet CFM, you can implement the
bidirectional fault notification.
8.12 Associating Ethernet CFM with VPLS
By associating Ethernet CFM with the VPLS, you can implement end-to-end detection,
advertisement, verification, and location of connectivity faults in the VPLS scenario.
8.13 Associating Ethernet CFM with VLL (by Using Sub-interfaces for QinQ VLAN Tag
Termination)
In the scenario where PEs that send packets with double VLAN tags access a Virtual Leased
Line (VLL), you can 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.
8.14 Associating Ethernet CFM with VPLS (by Using Sub-interfaces for QinQ VLAN Tag
Termination)
In the scenario where PEs that send packets with double VLAN tags access a Virtual Private
LAN Service (VPLS) network, you can configure sub-interfaces for QinQ VLAN tag
termination on AC interfaces of the PEs to bind VSIs and then configure Ethernet CFM on the
PEs.
8.15 Associating Ethernet OAM with MPLS OAM or BFD
By associating Ethernet OAM with MPLS OAM or BFD, you can implement the fault
notification.
8.16 Configuring Ethernet CFM and 1+1 Protection of Multicast VLANs
Ethernet CFM can be used on working VLANs, detect connectivity faults of VLANs, and trigger
protection switchover, which can implement 1+1 multicast VLAN protection.
8.17 Maintaining Ethernet OAM
This section describes how to maintain Ethernet OAM. Detailed operations include deleting
CCM statistics, monitoring Ethernet OAM.
8.18 Configuration Examples
The following sections provide several examples for configuring fast BFD link detection.
Familiarize yourself with the configuration procedures against the networking diagram. Each
configuration example consists of the networking requirements, configuration roadmap,
configuration procedures, and configuration files.
