Configuring basic CFD settings

Enabling CFD

Step
1. Enter system view.
2. Enable CFD.

Configuring the CFD protocol version

Three CFD protocol versions are available: IEEE 802.1ag draft5.2 version, IEEE 802.1ag draft5.2
interim version, and IEEE 802.1ag standard version. Devices in the same MD must use the same
CFD protocol version. Otherwise, they cannot exchange CFD protocol packets.
If an MD is created by using the cfd md command or automatically generated by using the cfd
service-instance maid format command on a device, you cannot switch between the standard
version and draft5.2 version (or draft5.2 interim version). However, you can switch between the
draft5.2 version and draft5.2 interim version. This restriction does not apply to the device without an
MD configured.
To configure the CFD protocol version:
Step
1. Enter system view.
2. Configure the CFD protocol
version.

Configuring service instances

Before configuring the MEPs and MIPs, you must first configure service instances. A service
instance is a set of service access points (SAPs), and belongs to an MA in an MD.
A service instance is indicated by an integer to represent an MA in an MD. The MD and MA define the
level and VLAN attribute of the messages handled by the MPs in a service instance.
A service instance can be one that has an MD name or one that does not have an MD name. The
former applies to any CFD protocol version, and the latter only applies to the IEEE 802.1ag standard
version. You can select either one as needed.
An MD name must be in compliant with the specifications in table 21-19 in IEEE802.1ag-2007.
Configuring a service instance with the MD name
To create a service instance, create the MD and MA for the service instance first.
To configure a service instance:
