NOTE:
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

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.

Optional
By default, CFD uses the standard
version of IEEE 802.1ag.
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 it belongs to an MA in an MD.
