Tasks
functions
Typically, a port blocked by STP cannot receive or send CFD messages except in the following cases:
The port is configured as an outward-facing MEP.
•
The port is configured as a MIP or inward-facing MEP, which can still receive and send CFD
•
messages except CCM messages.

Configuring basic CFD settings

Enabling CFD

Enable CFD on all concerned devices.

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 a same MD must use the same CFD
protocol version. Otherwise, they cannot exchange CFD protocol packets.
To configure the CFD protocol version:

Enter system view
• Configure the CFD protocol
version
If an MD is created by using the cfd md command or generated automatically by using the cfd service-
instance maid format command on a device, you cannot switch between the standard and non-standard
versions (draft5.2 version and 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.

Configuring service instances

Before configuring the MEPs and MIPs, you must first configure service instances. A service instance is a
set of SAPs, and it belongs to an MA in an MD.
