Typically, a port blocked by the spanning tree feature 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.
For more information about the spanning tree feature, see Layer 2—LAN Switching Configuration Guide.
Configuring basic CFD settings
Enabling CFD
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable CFD. cfd enable By default, CFD is disabled.
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.
The MD and MA define the level attribute and VLAN attribute of the messages handled by the MPs in a
service instance. The MPs of the MA that has no VLAN attribute do not belong to any VLAN.
Follow these steps in strict order to configure a service instance with the MD name:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an MD.
cfd md md-name [ index
index-value ] level level-value
By default, no MD is created.
